Coinbase Tutorial. A Definitive Guide for Newcomers.
Coinbase Tutorial. A Definitive Guide for Newcomers.
As cryptocurrencies become more abundant throughout our society, more information must be prevalent to educate the newcomers into the world of cryptocurrency and blockchain technology. If you’re new to cryptocurrencies, then you’ve come to the right place as Coinbase is one of the simplest cryptocurrency trading platforms to get started on. Once you understand Coinbase, more advanced trading platforms such as Binance won’t seem as intimidating.
What is Coinbase?
Coinbase is a cryptocurrency trading platform which allows you to buy and sell five different cryptocurrencies: Bitcoin, Bitcoin Cash, Ethereum, Ethereum Classic, and Litecoin. Note that there are over thousands of different cryptocurrencies but these four are what Coinbase specializes in.
Making a Coinbase account
Creating a Coinbase account is very simple but there’s much more to it compared to something like creating a Reddit account. Be sure to have either your driver’s license, passport, or identification card at hand as you’ll be asked to provide this information via upload. Coinbase currently has a sign-up promotion going on. If you haven't signed up yet, sign up using this link and you'll receive $10 free in bitcoin (after you spend $100).
Why does Coinbase need to see my ID?
Coinbase needs to be able to verify your identify because they are a regulated financial service company operating in the US. As they state on their website:
As a regulated financial service company operating in the US we are periodically required to identify users on our platform. This ensures we remain in compliance with KYC/AML laws in the jurisdictions in which we operate, something that is necessary for us to be able to continue to offer digital currency exchange services to our customers.
Once you’ve created your account, you’ll have to wait until you get approved before you’re allowed to start buying and trading on the platform. This can take upwards of 7 days till approval. Coinbase will also make two distinct small charges towards your bank account. You will need to find these charges and register them into Coinbase as a part of the approval process. The time in which it’ll take to get approved will vary person to person, just be patient and you eventually will get approved. In the mean-time I highly recommend taking some extra steps done to ensure the security, and longevity of your account.
Securing Your Coinbase Account
Two Factor Authentication
Upon signing into your Coinbase account, you’ll be sent a text message containing a code in which you will have to input allowing you to access your account. This is a security measure done to ensure it is specifically you trying to access your account, it’s important to note that a hacker could still compromise your account through a social engineering attack with what is known as a phone porting attack. This attack is done after obtaining your phone number and various other personal information, the hacker will then call up your phone carrier impersonating you, and then attempt to port your number over to a new device. Once a hacker has access to your text messages, they can then access your account with your SMS two-factor authentication code. If you’d like to see a real example of how this can play out, Cody Brown shares his example of how he lost $8k worth of bitcoin to this attack. Anyways, the best way to prevent this is through the use of an authenticator. The most common being Google Authenticator. I don’t want to get into too much technical details as to how authenticators work. Think of it as a digital key, stored on a device that changes every 30 seconds. In order to enable authenticator for Coinbase, go to Settings > Security and Enable Authenticator as shown here. After that a prompt will appear along with a QR code and a secret code (comprised of a random string of 16 letters & numbers). You will need to open up your Google Authenticator app and scan in your QR code. You will also need to write down your secret code and keep it in a safe place such as a safe and/or security deposit box. Once enabled, any time you wish to access your Coinbase account or make trades/transfers, you will need access to the 6-digit code provided by your authenticator. IMPORTANT: If you lose access to the device you’ve enacted authenticator on, you ABSOLUTELY WILL NOT be able to recover your account UNLESS you have that 16 digit secret code. This is a serious matter that should be taken with serious caution. It is important you take preventative security measures to ensure the security of your cryptocurrency. I highly recommend calling your bank and opening a security deposit box. This will mostly likely cost a yearly fee but the peace of mind alone is worth it IMO.
I’d like to briefly touch on phishing schemes. Phishing is the act of attempting to obtain personal information through the use of social engineering. Common phishing schemes/methods include: fraudulent e-mails in which the sender tries to impersonate an entity of authority (we’ve all received these sketchy e-mails before) and websites registered under the misspelling of a popular domain. In the world of crypto, it is essential to be attentive to schemes like these as it is much easier to fall victim than you may think. The anonymity of crypto alone makes it very appealing to hackers & scammers. You should always be on the lookout for fraudulent schemes. Some preventative actions you may want to consider taking:
Creating a bookmarks folder of all the popular crypto-related sites you visit
Creating email inbox rules to distinguish trusted entities.
As a safety precaution, ensure you have authenticator enabled throughout all your crypto-related accounts with the security keys kept in a safety deposit box.
Use a hardware wallet to store your cryptocurrency instead of keeping them on exchanges (I’ll touch more on this later)
Funding Your Coinbase Account
Congratulations, your Coinbase account got approved! You can now start funding your account… or so you thought. Upon your first cryptocurrency purchase with Coinbase, it is very likely your bank will automatically flag the purchase as fraudulent. If this happens to you (which it most likely will), you will need to call up your bank and let them know to let the purchase go through. Once you’ve taken care of that, buying and selling cryptocurrency is relatively self-explanatory. Just go to Buy/Sell in the menu and choose which currency you’d like to buy/sell as shown below. https://imgur.com/isNuaSJ
Coinbase has weekly limits as to how much cryptocurrency you may purchase. Your limits will not start out this high but increase with proper verification and the longer you have an account. Weekly Buy Limits
Bank Account: $25,000
Credit/Debit Card: $7,500
Weekly Sell Limits
Credit/Debit Card and bank account purchases are both instantaneous, however, for bank account purchases, it'll take 5-7 business days for you to see the charge in your account. For information see:
There’s three distinct fee’s you will encounter with Coinbase.
Conversion & Exchange Fees: These are fees you’ll encounter through the buying, selling or exchanging of crypto. A fee is charged when you convert fiat to crypto.
Transfer Fees: A fee is charged if you’re transferring crypto to a different wallet (IE: Crypto Binance). Note that if this wallet happens to be another Coinbase wallet, there is no fee.
Mining Fees: These's are inherent fee's you'll encounter with any sort of crypto transaction. Mining fee's will also change depending on which cryptocurrency you are purchasing. I don't want to delve to much into the technical aspects as to why this is (as it can get very technical). I'll have to save this for a later post.
Note that the Bitcoin network is notorious for insanely high fee's. Purchase and transaction fee's upwards of $50+ are not uncommon during periods of high network congestion. Using Bitcoin to purchase something like a cup of coffee is completely trivial, and as we advance forward into the space, it's becoming more apparent that Bitcoin's main use case will be that of a digital gold rather than a global payment network.
Lowest Possible Fee With Coinbase
If you're going to be making large crypto purchases through Coinbase, ideally you'd want to get the lowest fee possible. I have found that the best way to do this is by your linking a bank account rather then by purchasing through debit/credit card. See photo.
Funding via bank account: 1.46% fee
Funding via debit/credit card: 3.83% fee
See photo. As you can see, both allow instantaneous availability of funds. However, it'll take 5-7 business days for the bank account transfer charge to appear in your account. Note: The fee you receive will also depend on how large of an amount you are purchasing. Expect fees to be a bit higher for smaller purchasing amounts and lower for larger amounts.
It's important to know that fees will change depending on what country you're from and what cryptocurrency you happen to be purchasing. For more information on Coinbase fees I highly recommend visiting their fee disclosure page.
Avoiding Coinbase Transfer Fees Using GDAX
There is a bit of loophole to avoid Coinbase transfer fees. This is done through Coinbase’s advanced trading platform known as GDAX. It looks intimidating, but it’s a lot easier to use than they make it seem. Luckily, as Coinbase user, you technically already have a GDAX account. Simply follow the sign-up steps for GDAX, and you’ll find your information pre-populated. No need for long wait-times for verification etc. To mitigate Coinbase transfer fees, send your money: Coinbase - GDAX - wallet of your choice
Sending & Receiving Cryptocurrency
Sending and receiving crypto with Coinbase is super easy…
Go to Accounts in the menu, look for the currency you’d like to send, then click Send. A prompt will come up instructing you to put in the recipients address and the amount you’d like to send. Ethereum example.
Go to Accounts in the menu, look for the currency you’d like to receive, then click Receive. A QR code and random string of numbers will appear. That random string of letters & numbers is your wallet address. This string is what you’d give to someone if you were looking to receive crypto. Your wallet address is also crypto specific. This means that if you try to send Litecoin to your Bitcoin wallet address, the transaction will fail. Random LPT: If you’re ever needing to transfer a large amount of crypto to another wallet, I recommend sending a test amount which is basically just a small amount of crypto. If said small amount appears in the wallet, you know you have the correct address. If not… you may need to just wait a bit longer and hopefully it will appear, or you’ve sent it to the wrong wallet address.
Securing Your Cryptocurrency
There are many ways you could go about securing your cryptocurrency. I’m going to discuss two.
The Vault is a feature Coinbase offers free of charge to safeguard your funds by adding multiple layers of security. With the vault, there is a designated time frame for withdrawals. This helps to safeguard against hackers getting into and emptying your account. Additionally, you can have other people (or email addresses) needed to confirm these withdrawals for an added layer of security. Warning: The vault is a feature you should use if you are planning on holding your cryptocurrency for a longer period of time. It is not recommended if you are looking to turn quick profits through buying and selling often due to the 3 day waiting period for withdrawals.
Ledger Nano S
The Ledger Nano S is a cryptocurrency hardware wallet. It allows you to store your cryptocurrency in physical device akin to that of a USB drive. You would then ideally keep this in a safe at home. This is my personal preferred method of storing cryptocurrency because I don’t have to worry about hackers potentially gaining access to my cryptocurrency online, rather, that security falls into my own hand. I just have to make sure I don’t lose or damage my Ledger, and even if I managed to do that, there is a 16 word recovery phrase provided by the Ledger in the event of a lost, damaged, or stolen Ledger. As long as you have the recovery phrase, you can recover all your cryptocurrency. So after purchasing crypto through Coinbase, instead of leaving my digital goods on the exchange, I transfer it to cold storage (which is another word for hardware wallet IE: Ledger Nano S).
My Primary use of Coinbase
I primarily use Coinbase as an easy access point into the crypto world. Coinbase makes it very easy to purchase the largest of cryptocurrencys and once you have access to these, you can start purchasing more niche cryptocurrencies such as Ripple, EOS, IOTA, NEO, etc... You would do this through the use of much larger exchange such as Binance. You cannot directly convert fiat to crypto with Binance yet. So in order to fund a Binance account, you need to convert your fiat to crypto through an exchange that allows you to do so, (this is where Coinbase comes into play) send that crypto to your Binance account, then make a purchase. The way I go about doing this is:
1st I purchase Ethereum through Coinbase. I purchase Ethereum instead of Bitcoin, because as I mentioned before, Bitcoin is notorious for insanely mining and transaction fees. Ethereum has much lower fees.
2nd I send said Ethereum to my Binance account
3rd Once I receive that Ethereum on my Binance account, I make my niche cryptocurrency purchase through the Binance exchange.
I have a step-by-step guide that details out this process. You can view it here. PHEWWWW. That was a lot of words... Anyways, I hope this was beneficial to you crypto newbies out there. I plan on making more tutorials like this in the future :) If you have any questions, just leave them in the comments sections down below. I’m sure either myself or the community would be able to respond.
Crypto Wallet Guide Humans have come a long way from the barter trading (trading goods without using the money) to gold, then later to paper currency and now we have arrived in the age of digital currency. There are more than 2000 cryptocurrencies in the world with a market capitalization of around $175 billion, it is necessary to know about them. Where these currencies are stored? How does the crypto wallet work? If You are still reading this, it says you are a beginner and want to explore the crypto world. To understand the crypto concept, first, know about the crypto wallets. What Is Cryptocurrency Wallet? A cryptocurrency wallet is a software program used to store, send, receive private and public keys and can be used to track ownership. It enables you to send and receive digital coins through blockchain. Wallets are a necessary factor for investing and owning cryptocurrencies of any sort. However, Some wallets are built for a single cryptocurrency( bitcoin and coins forked from bitcoin like bitcoin cash), some can be used for more than one coin(multi cryptocurrency wallet), some wallets you’ll manage yourself, and some will be custodial. What Are Public & Private Keys? A public key is a unique identifier for a person and a private key is like a password similar to an ATM pin. A sender will require the public key of the receiver to send him the cryptocurrency and the receiver will be able to access and use these cryptocurrencies by using the private key. A private key must be protected in order to avoid fraudulent activities such as hacking, stealing of cryptocurrencies, etc. A public key can be extracted from a private key, but a private key can never be extracted from a public key. A private key should always be kept safe. Exposing it would be vulnerable for various hacks and stealing of the coins by with whom you have shared. sending them to another wallet which they control. Example of a private key: N2nGYRCBbs6ZRs8w5LHam4r85ikxBzhRNgpNJjqk7D5vrpuaVJB Example of a public key: 958ikZuaAbGkzXuFL9sfGHYj9ethop8qMh How Does a Cryptocurrency Wallet Work? Cryptocurrency wallets work like the safety deposit boxes. Unlike traditional pocket wallets, where they don’t store digital currency. The crypto wallets store your private and public keys and interface with multiple blockchains. Thus, users can track their balance, send money and conduct other operations. Moreover, currencies don’t get stored in any single place. Also, it is advised not to store the cryptocurrencies on the wallet offered by the particular exchange, because the exchange will own your private key. So better you transfer it to your own crypto wallet to have control over the cryptocurrencies owned by you. A wallet address is the same as a bank account number. Providing your bank account number to other people, as they need it to transfer your funds. For example: This is like your friend transferring you money, so he needs your bank account number. In the world of cryptocurrency, if anyone wants to transfer you crypto coins, you should provide him with your wallet address. Similar, like in the real world, however, no two wallets can have the same address, which means that there is no risk of your fund being to transfer to others address. Moreover, there is no limit to the 5number of wallet addresses you create. Different Types of Crypto Wallets There are multiple types of wallets that provide different ways to store and access your digital currency. Hot Wallets vs Cold Wallets you might come across frequently with the terms “hot wallets” and “cold wallets”. All crypto wallets fall under these two types. In general, whatever is connected to the internet is less secure than something that is not. This is the difference, where “hot” wallets are connected to the internet and “cold” wallets” are not. Online, desktop and mobile wallets are hot wallets, while hardware and paper wallets are cold wallets. 1). Software Wallet: There are three forms of software wallets: Desktop wallets: These are installed on a laptop or a PC, and can be accessed from a single computer. Although they provide high security, if the computer is attacked by the virus, there is a chance of losing your wallet. Online wallets: These wallets run on the cloud and can be accessed from any device. Here, your keys are stored online. Mobile wallets: These wallets that run on an application in a smartphone; they are simpler than the desktop wallets and can be used anywhere. 2). Full Node Wallet: Here you can control your private keys and provide a full copy of the blockchain. Essentially every coin has an official wallet of this type and that can be found on the official GitHub of the site. “Official” means endorsed by the developers who created the coin.” Many cryptos are decentralized, so there is no real official anything. 3). Coin-Specific: A wallet which works only with a specific coin. 4). Network-Specific: A wallet which can hold multiple tokens on a single network. 5). Hardware Wallet: These type of hardware are specifically built to hold cryptocurrency and keep it safe. This includes USB devices. Moreover, these devices can go online to make transactions and get data and then can be taken offline for transportation and security. 6). Paper Wallet: This type of wallet lets you to both send and receive digital currency using a paper wallet. You can take a print of your QR code for both a private and public key. With this feature, you can completely avoid storing digital information about your currency by using a paper wallet. 7). Custodial Wallet: In Custodial wallet, you can’t control your keys directly. Most exchange wallets are custodial wallets. 8). Multisignature Wallet: It requires multiple parties to sign a transaction for any digital money to be spent. Multisignature wallets are designed to have more layer of security. How To Choose a Wallet? Here are some ideas on how to choose the best wallet for you.Hardware and paper wallets are the best to secure funds. Also, We always suggest official or officially endorsed wallet for any given coin. Ledger Nano S: Multi-currency support, Built-in Display, Easy to operate, Security, Backup and restoration. Ledger Blue: Malware proof, Multiple currencies, Secure elements. Jaxx: Exclusive design, Easy to use, Personalized key, available on multiple OS. Edge wallets: Security, Multi-Currency Support, Easy to use. Exodus : Multi-currencies, Complete security, Great design, Multi-currencies. Coinpayment: Bit-go integrated, Online store acceptable, vault, multi-coin wallet. Most top performing wallets are (Binance, Coinbase, etc.) and they have exchanges too that offers for easy and quick trading between Bitcoin and other crypto or bitcoin and fiat currencies. Online wallets are prone to security hack and therefore should be used as little as possible. It will be safe to divide your funds among the different types of wallets. How to Register in a Wallet? If you are a newbie to the crypto world, then read these points before proceeding: Download the official wallet from the website. Register for a custodial wallet service ‘Coinbase’ or non-custodial wallet service like ‘Blockchain’ Wallet (which handles both wallet and exchange with one account). Purchase a hardware wallet like TREZOR for storage. Use a universal software wallet or any other wallet that meet your needs like the ones mentioned above. Coinbase and TREZOR are one of the good major choices, since, they have guides and can be kept safe with the best execution, and also, don’t need to download the full blockchain for a coin.

Cryptocurrency Terms And Definitions - Common Crypto Words To Know
The blockchain community is not left out when it comes to the use of jargon and phrases. The use of words that look strange to those who are not involved in crypto is totally inevitable. It’s definitely going to be difficult for anyone not in this space to understand words like “ERC20, ICO or gas. So in order to help such people out, we have made a list of the most common cryptocurrency terms and definitions. Please sit back and enjoy your ride. Cryptocurrency Terms And Definitions One can categorize these terms into various parts. First of all, we will deal with general cryptocurrency terms and definitions. Blockchain Blockchains are distributed ledgers which are secured by cryptography. Everyone has access to read the information on every blockchain which means they are essentially public databases but the data update can only be done by the data owners. In the case of blockchains, data doesn’t remain on a single centralized server, they are copied across hundreds of thousands of computers worldwide. Projects such as Ethereum, Vechain, EOS etc. fall under this class of technology. Mining: The means of trying to ‘solve’ the next available block. One needs huge amounts of computer processing power to carry this out effectively. There is always a reward for doing this. Mining rig: A specially designed computer that processes proof-of-work blockchains such as Ethereum. They consist of multiple high-end graphic processors (GPUs) so as to maximize their processing power. Node: This is a computer that has a copy of the blockchain and is working to keep it in a good shape. PoW: The full meaning of this is Proof-of-work. The Ethereum network currently makes use of this algorithm. PoS: Its full meaning is Proof-of-stake. It is the proposed future algorithm for Ethereum. Those that own ETH will be able to lock up all or a portion of their ether for a given amount of time in order to ‘vote’ and generate network consensus instead of mining in its current form. Stakeholders will get rewards in form of ETH by doing so. Fork: This takes places when a certain blockchain splits into two different chains. This usually happens in the crypto space when new ‘governance rules’ are infused into the blockchain’s code. Software wallet: A crypto-currency storage that exists purely on a computer as software files. You can generate these kinds of wallets for free from diverse sources. MyEtherWallet (MEW) is one of the most popular sources around. Hardware wallet: A device that one can securely keep cryptocurrency. People often say that these wallets are the most secure way to store cryptocurrency. Examples of the most common hardware wallet models around are Ledger Nano S and Trezor. Cold storage: This is a way of moving your cryptocurrency from an online wallet to an offline one, as a means of safekeeping them from hack. There are a lot of ways to carry this out. Some methods that are commonly used include: · Using a hardware wallet to store your cryptocurrency. · By printing out the QR code of a software wallet and keeping it somewhere which is safe. · You can also move the files of a software wallet onto an external storage device such as USB drive and keeping it somewhere safe. Trading Related Cryptocurrency Terms And Definitions Exchange: These are websites where people trade (buy and sell) their cryptocurrencies. Some of the popular crypto exchanges we have around include Binance, Poloniex, Bittrex etc. Market order / market buy / market sell: A sale or purchase which is made on an exchange at the current price. A market buy acquires the cheapest Bitcoin available on the order book while a market sell fills up the most high-priced buy order on the books. Limit order / limit buy / limit sell: These are orders which are placed by traders to buy or sell a cryptocurrency when the price reaches a certain amount. They are pretty much like ‘for-sale’ signs you see on goods. Sell wall / buy wall: Cryptocurrency traders are able to see the current limit buy and sell points using a depth chart. The chart’s graphical representation is very much like a wall. FIAT: Refer to a government-issued currency. An example is the US dollar. Whale: A person who owns huge amounts of cryptocurrency. Margin trading: This is an act of increasing the intensity of a trade by using your existing coins. It is very risky for an inexperienced trader to partake in this. Stay safe!! Going long: This is a margin trade that gives profit if the price goes up. Going short: It is a margin trade that gives profit if the price goes down. Bullish: Being optimistic that the price of cryptocurrency is going to increase. Bearish: This is an expectation that the price of cryptocurrency is going to decrease. ATH: This simply means All-Time-High. This is the highest point that has been reached by a particular coin or token. Take for instance, Bitcoin’s ATH is about $20,000 and this was achieved around December 2017 and January 2018. Altcoin: A word used to qualify other cryptocurrencies which is not Bitcoin. Examples of altcoins are Ripple, NEO, EOS, Vechain, Electroneum etc. Tokens: These are ‘currency’ of projects which are hosted on the ethereum network. They raise money by issuing their own tokens to the general public. Tokens have a significant use in the project's ecosystem. Examples of tokens are Enjin Coin (ENJ), Zilliqa (ZIL), OmiseGO (OMG), Augur (REP) etc. ICO: The full meaning is Initial Coin Offering. This is synonymous to an IPO in the non-crypto world. Startups give out their own token in exchange for Bitcoin or ether. Shilling / pumping: An act of advertising another cryptocurrency. It is mostly done in a way that tricks as many people as possible into believing that a coin or token will get to a higher price in the future. Market Cap: This is the total value of a cryptocurrency. To calculate this, one has to multiply the total supply of coins by the current market price. You can get a run-down of several cryptocurrency projects on Coinmarketcap. Stable coin: This is a cryptocurrency which has an extremely low volatility. You can use a stable coin to trade against the overall crypto market. Arbitrage: A situation where a trader takes advantage of a difference in the price of the same coin / token on two different exchanges. FOMO: Simply means Fear Of Missing Out. That overwhelming feeling that one needs to get on board when there is a massive rise in the price of a commodity. This is also applicable in the crypto space. FUD: Fear, Uncertainty, and Doubt. It is a baseless negativity which is spread intentionally by someone or a group of people who want the price of cryptocurrency to decrease. FUDster: A person who spreads FUD. Pump And Dump: This happens when an altcoin gets a ton of attention, leading to a massive increase in price, and likewise followed by a big price crash of that altcoin. ROI: Return on Investment. The percentage profit a trader makes on an initial investment (i.e. A 100% ROI simply indicates that a trader doubled his money). TA: Trend Analysis or Technical Analysis. A way of examining current coin charts so as to make predictions for the next market movement. Next, we will be moving on to crytocurrency terms and definitions that are ethereum related. Dapp: Decentralized Application. It is an application that uses a decentralized peer-to-peer network like Ethereum smart contract as its back-end code. Bagholder: A person who still holds on to a particular altcoin despite having a pump and dump crash. Smart contract: This is a code that is deployed onto the Ethereum blockchain, it often helps with the direct interaction of how money flows from one point to another. The Flippening: A future event showing the capacity of Ethereum’s market cap (or some other cryptocurrency) surpassing Bitcoin’s market cap, making Ethereum the most ‘valuable’ crypto-currency. Gas: It is a measurement of the amount of processing needed by the ethereum network to execute a transaction. More complex transactions like deploying a smart contract onto the network requires more gas than sending ether from one wallet to another which is obviously a simpler operation. Gas price: This is the amount of ether an initiator of a transaction is willing to spend for each gas unit on a transaction. The higher the gas price, then the faster the processing of the transaction. Wei: It is the smallest denomination of ether. Gwei: This is a denomination of ether (ETH). Gwei is the unit for measuring gas prices. 1 Ether = 1,000,000,000 Gwei (109). MEW: MyEtherWallet is a site where users can generate ethereum wallets for free. We also have a handful of cryptocurrency terms and definitions that are memes. See some of them below; Hodl: People use this word when signifying that a person is keeping his coins / tokens for a long period of time. A couple of years back, someone on a Bitcoin forum made a post with a typo HODL in place of HOLD. Ever since then, this term has become one of the most popularly used term in crypto. Mooning: In crypto, this term comes to play when the price of cryptocurrencies move up astronomically. Lambo: This is highly synonymous with crypto. You can't leave out this word when discussing about cryptocurrency terms and definitions. This is the car we’re all goona buy when crypto makes us rich. This is gentlemen: People use this phrase when pointing out positive things that are currently taking place in the cryptosphere. Now that you are conversant with some of the commonly used cryptocurrency terms and definitions, you can now go out there and showcase your new crypto vocabulary to the world.

Find the answer after reading this article. Public/Private Key The public key is the digital code you give to someone that wants to transfer ownership of a unit of cryptocurrency to you; and a private key is what you need to be able to unlock your own wallet to transfer a unit of a cryptocurrency to someone else. The encoding of information within a wallet is done by the private and public keys. That is the main component of the encryption that maintains the security of the wallet. Both keys function in simultaneous encryption systems called symmetric and asymmetric encryption. The former, alternatively known as private key encryption, makes use of the same key for encryption and decryption. The latter, asymmetric encryption, utilizes two keys, the public and private key, wherein a message-sender encrypts the message with the public key, and the recipient decodes it with their private key. The public key uses asymmetric algorithms that convert messages into an unreadable format. A person who possesses a public key can encrypt the message for a specific receiver. Accessing wallets Methods of wallet access vary depending on the type of wallet being used. Various types of currency wallets on an exchange will normally be accessed via the exchange’s entrance portal, normally involving a combination of a username/password and optionally, 2FA (Two factor authentication, which we explain in more detail later). Whereas hardware wallets need to be connected to an internet enabled device, and then have a pin code entered manually by the user in possession of the hardware wallet in order for access to be gained. Phone wallets are accessed through the device on which the wallet application has been downloaded. Ordinarily, a passcode and/or security pattern must be entered before entry is granted, in addition to 2FA for withdrawals. Satoshi Nakamoto built the Satoshi client which evolved into Bitcoin in 2009. This software allowed users to create wallets and send money to other addresses. However, it proved to be a nightmarish user experience, with many transactions being sent to incorrect addresses and private keys being lost. The MtGox (Magic the Gathering Online exchange, named after the original intended use of the exchange) incident, which will be covered in greater detail later, serves as a reminder of the dangers present in the cryptosphere regarding security, and the need to constantly upgrade your defenses against all potential hacks. The resulting loss of 850k BTC is a still unresolved problem, weighing heavily on the victims and the markets at large. This caused a huge push for a constantly evolving and improving focus on security. Exchanges that developed later, and are thus considered more legitimate and secure, such as Gemini and Coinbase, put a much greater emphasis on vigilance as a direct result of the MtGox hacking incident. We also saw the evolution of wallet security into the physical realm with the creation of hardware wallets, most notable among them the Ledger and Trezor wallets. Types of Wallets & Storage Methods The simplest way to sift through the dozens of cryptocurrency storage methods available today, is to divide them up into digital and non-digital, software and hardware wallets. There are also less commonly used methods of storage of private keys, like paper wallets and brain wallets. We will examine them all at least briefly, because in the course of your interaction with cryptocurrencies and Blockchain technology, it is essential to master all the different types of hardware and software wallets. Another distinction must be made between hot wallets and cold wallets. A hot wallet is one that is connected to the internet, and a cold wallet is one that is not. Fun fact: The level below cold storage, deep cold storage has just recently been implemented by the Regal RA DMCC, a subsidiary of an internationally renowned gold trading company licensed in the Middle East. After having been granted a crypto trading license, Regal RA launched their “deep cold” storage solution for traders and investors, which offers the ability to store crypto assets in vaults deep below the Almas Tower in Dubai. This storage method is so secure that at no point is the vault connected to a network or the internet; meaning the owners of the assets can be sure that the private keys are known only to the rightful owners. Lets take a quick look at specific features and functionality of varieties of crypto wallets. Software wallets: wallet applications installed on a laptop, desktop, phone or tablet. Web Wallets: A hot wallet by definition. Web Wallets are accessible through the web browser on your phone or computer. The most important feature to recognize about any kind of web wallet, is that the private keys are held and managed by a trusted third party. MyEtherWallet is the most commonly used non-exchange web wallet, but it can only be used to store Ethereum and ERC-20 tokens. Though the avenue of access to MEW is through the web, it is not strictly speaking a web wallet, though this label will suffice for the time being. The MEW site gives you the ability to create a new wallet so you can store your ETH yourself. All the data is created and stored on your CPU rather than their servers. This makes MEW a hybrid kind of web wallet and desktop wallet. Exchange Wallets: A form of Web Wallet contained within an exchange. An exchange will hold a wallet for each individual variety of cryptocurrency you hold on that exchange. Desktop Wallets: A software program downloaded onto your computer or tablet hard drive that usually holds only one kind of cryptocurrency. The Nano Wallet (Formerly Raiwallet) and Neon wallet for storage of NEO and NEP-5 tokens are notable examples of desktop wallets Phone Wallets: These are apps downloaded onto a mobile phone that function in the same manner as a desktop wallet, but actually can hold many different kinds of cryptocurrency. The Eidoo Wallet for storing Ethereum and its associated tokens and Blockchain Wallet which currently is configured to hold BTC, ETH and Bitcoin Cash, are some of the most widely used examples. Hardware wallets — LedgeTrezoAlternatives Hardware wallets are basically physical pathways and keys to the unique location of your crypto assets on the Blockchain. These are thought to be more secure than any variety of web wallet because the private key is stored within your own hard wallet, an actual physical device. This forcibly removes the risk your online wallet, or your exchange counter party, might be hacked in the same manner as MtGox. In hardware wallet transactions, the wallet’s API creates the transaction when a user requests a payment. An API is a set of functions that facilitates the creation of applications that interact and access features or data of an operating system. The hardware then signs the transaction, and produces a public key, which is given to the network. This means the signing keys never leave the hardware wallet. The user must both enter a personal identification number and physically press buttons on the hardware wallet in order to gain access to their Blockchain wallet address through this method, and do the same to initiate transfers. Paper Wallets Possibly the safest form of cryptocurrency storage in terms of avoiding hacking, Paper Wallets are an offline form of crypto storage that is free to set up, and probably the most secure way for users, from beginners to experts, to hold on to their crypto assets. To say it simply, paper wallets are an offline cold storage method of storing cryptocurrency. This includes actually printing out your public and private keys on a piece of paper, which you then store and save in a secure place. The keys are printed in the form of QR codes which you can scan in the future for all your transactions. The reason why it is so safe is that it gives complete control to you, the user. You do not need to worry about the security or condition of a piece of hardware, nor do you have to worry about hackers on the net, or any other piece of malware. You just need to take care of one piece of paper! Real World Historical Examples of Different Wallet Types Web Wallet: Blockchain.info Brief mechanism & Security Blockchain.info is both a cryptocurrency wallet, supporting Bitcoin, Ethereum and Bitcoin cash, and also a block explorer service. The wallet service provided by blockchain.info has both a Web Wallet, and mobile phone application wallet, both of which involve signing up with an email address, and both have downloadable private keys. Two Factor Authentication is enabled for transfers from the web and mobile wallets, as well as email confirmation (as with most withdrawals from exchanges). Phone Wallet: Eidoo The Eidoo wallet is a multi-currency mobile phone app wallet for storage of Ethereum and ERC-20 tokens. The security level is the standard phone wallet level of email registration, confirmation, password login, and 2 factor authentication used in all transfers out. You may find small volumes of different varieties of cryptocurrencies randomly turning up in your Eidoo wallet address. Certain projects have deals with individual wallets to allow for “airdrops” to take place of a particular token into the wallet, without the consent of the wallet holder. There is no need to be alarmed, and the security of the wallet is not in any way compromised by these airdrops. Neon Wallet The NEON wallet sets the standard for web wallets in terms of security and user-friendly functionality. This wallet is only designed for storing NEO, Gas, and NEP-5 tokens (Ontology, Deep Brain Chain, RPX etc.). As with all single-currency wallets, be forewarned, if you send the wrong cryptocurrency type to a wallet for which it is not designed, you will probably lose your tokens or coins. MyEtherWallet My Ether Wallet, often referred to as MEW, is the most widely used and highly regarded wallet for Ethereum and its related ERC-20 tokens. You can access your MEW account with a hardware wallet, or a different program. Or you can also get access by typing or copying in your private key. However, you should understand this method is the least safe way possible,and therefore is the most likely to result in a hack. Hardware: TrezoLedger Brief History Mechanism and Security A hardware wallet is a physical key to your on-chain wallet location, with the private keys contained within a secure sector of the device. Your private key never leaves your hardware wallet. This is one of the safest possible methods of access to your crypto assets. Many people feel like the hardware wallet strikes the right balance between security, peace of mind, and convenience. Paper Wallet Paper wallets can be generated at various websites, such as https://bitcoinpaperwallet.com/ and https://walletgenerator.net/. They enable wallet holders to store their private keys totally offline, in as secure a manner as is possible. Real World Example — Poor Practices MtGox Hack history effects and security considerations MtGox was the largest cryptocurrency exchange in the world before it was hacked in 2014. They were handling over 70% of BTC transactions before they were forced to liquidate their business. The biggest theft of cryptocurrency in history began when the private keys for the hot wallets were stolen in 2011 from a wallet.dat file, possibly by hacking, possibly by a rogue employee. Over the course of the next 3 years the hot wallets were emptied of approximately 650000 BTC. The hacker only needed wallet.dat file to access and make transfers from the hot wallet, as wallet encryption was only in operation from the time of the Bitcoin 0.4.0 release on Sept 23rd 2011. Even as the wallets were being emptied, the employees at Mt Gox were apparently oblivious to what was taking place. It seems that Mt Gox workers were interpreting these withdrawals as large transfers being made to more secure wallets. The former CEO of the exchange, Mark Karpeles, is currently on trial for embezzlement and faces up to 5 years in prison if found guilty. The Mt Gox hack precipitated the acceleration of security improvements on other exchanges, for wallets, and the architecture of bitcoin itself. As a rule of thumb, no small-to-medium scale crypto holders should use exchange wallets as a long-term storage solution. Investors and experienced traders may do this to take advantage of market fluctuations, but exchange wallets are perhaps the most prone to hacking, and storing assets on exchanges for an extended time is one of the riskiest ways to hold your assets. In a case strikingly similar to the MtGox of 2011–2014, the operators of the BitGrail exchange “discovered” that approximately 17 million XRB ($195 million worth in early 2018) were missing. The operators of the exchange were inexplicably still accepting deposits, long after they knew about the hack. Then they proceeded to block withdrawals from non-EU users. And then they even requested a hard fork of the code to restore the funds. This would have meant the entire XRB Blockchain would have had to accept all transactions from their first “invalid” transaction that were invalid, and rollback the ledger. The BitGrailexchange attempted to open operations in May 2018 but was immediately forced to close by order of the Italian courts. BitGrail did not institute mandatory KYC (Know your customer) procedures for their clients until after the theft had been reported, and allegedly months after the hack was visible. They also did not have 2 factor authentication mandatory for withdrawals. All big, and very costly mistakes. Case Study: Good Practice Binance, the Attempted Hack During the 2017 bull run, China-based exchange Binance quickly rose to the status of biggest altcoin exchange in the world, boasting daily volumes that surged to over $4 billion per day in late December. Unfortunately, this success attracted the attention of some crafty hackers. These hackers purchased domain names that were confusingly similar to “binance.com”. And then they created sufficiently convincing replica websites so they could phish traders for their login information. After obtaining this vital info, the scammers created API keys to place large buy orders for VIAcoin, an obscure, low volume digital currency. Those large buy orders spiked VIA’s price. Within minutes they traded the artificially high-priced VIA for BTC. Then they immediately made withdrawal requests from the hacked BTC wallets to wallets outside of the exchange. Almost a perfect fait accompli! But, Binance’s “automating risk management system” kicked in, as it should, and all withdrawals were temporarily suspended, resulting in a foiled hacking attempt. Software Wallets Web/Desktop/Phone/Exchange Advantages and Limitations As we said before, it is inadvisable to store crypto assets in exchange wallets, and, to a lesser extent, Web Wallets. The specific reason we say that is because you need to deliver your private keys into the hands of another party, and rely on that website or exchange to keep your private key, and thus your assets, safe. The advantages of the less-secure exchange or web wallets, are the speed at which you can transfer assets into another currency, or into another exchange for sale or for arbitrage purposes. Despite the convenience factor, all software wallets will at some point have been connected to the internet or a network. So, you can never be 100% sure that your system has not been infected with malware, or some kind of keylogging software, that will allow a third party to record your passwords or private keys. How well the type of storage method limits your contact with such hazards is a good way to rate the security of said variety of wallet. Of all the software wallets, desktop and mobile wallets are the most secure because you download and store your own private key, preferably on a different system. By taking the responsibility of private key storage you can be sure that only one person has possession of it, and that is you! Thereby greatly increasing the security of your crypto assets. By having their assets in a desktop wallet, traders can guard their private key and enjoy the associated heightened security levels, as well keep their assets just one swift transfer away from an exchange. Hardware Wallets Advantages and Limitations We briefly touched on the features and operation of the two most popular hardware wallets currently on the market, the Ledger and Trezor wallets. Now it will be helpful to take a closer look into the pros and cons of the hardware wallet storage method. With hardware wallets, the private keys are stored within a protected area of the microcontroller, and they are prevented from being exported out of the device in plain text. They are fortified with state-of-the-art cryptography that makes them immune to computer viruses and malware. And much of the time, the software is open source, which allows user validation of the entire performance of the device. The advantages of a hardware wallet over the perhaps more secure paper wallet method of crypto storage is the interactive user experience, and also the fact that the private key must at some stage be downloaded in order to use the paper wallet. The main disadvantage of a hardware wallet is the time-consuming extra steps needed to transfer funds out of this mode of storage to an exchange, which could conceivably result in some traders missing out on profits. But with security being the main concern of the vast majority of holders, investors and traders too, this slight drawback is largely inconsequential in most situations. Paper Wallets Advantages and Limitations Paper wallets are thought by some to be the safest way to store your crypto assets, or more specifically, the best method of guarding the pathways to your assets on the Blockchain. By printing out your private key information, the route to your assets on the Blockchain is stored 100% offline (apart from the act of printing the private key out, the entire process is totally offline). This means that you will not run the risk of being infected with malware or become the victim of keylogging scams. The main drawback of using paper wallets is that you are in effect putting all your eggs in one basket, and if the physical document is destroyed, you will lose access to your crypto assets forever. Key things to keep in mind about your Wallet Security: Recovery Phrases/Private Key Storage/2FA/Email Security Recovery phrases are used to recover the on-chain location for your wallet with your assets for hardware wallets like ledgers and Trezors that have been lost. When you purchase a new ledger for example, you just have to set it up again by entering the recovery phrase into the display and the lost wallets will appear with your assets intact. Private key storage is of paramount importance to maintain the safety of your on-chain assets! This should be done in paper wallet form, or stored offline on a different computer, or USB device, from the one you would typically use to connect to the 2 Factor Authentication (2FA) sometimes known as “two step authentication”. This feature offers an extra security layer when withdrawing funds from cryptocurrency wallets. A specialized app, most commonly Google Authenticator, is synced up to the exchange to provide a constantly changing code. This code must be entered within a short time window to initiate transfers, or to log into an exchange, if it has also been enabled for that purpose. You must always consider the level of fees, or the amount of Gas, that will be needed to carry out the transaction. In times of high network activity Gas prices can be quite high. In fact, in December 2017 network fees became so high that some Bitcoin transactions became absolutely unfeasible. But that was basically due to the anomalous network congestion caused by frantic trading of Bitcoin as it was skyrocketing in value. When copying wallet addresses, double check and triple check that they are correct. If you make a mistake and enter an incorrect address, it is most likely your funds will be irretrievably lost; you will never see those particular assets again. Also check that you haven’t input the address of another one of your wallets that is designed to hold a different variety of cryptocurrency. You would similarly run the very great risk of losing your funds forever. Or, at the very least, if you have sent the wrong crypto to a large exchange wallet, for example on Coinbase, maybe you could eventually get those funds back, but it would still entail a long and unenjoyable wait. How to Monitor Funds There are two ways to monitor you funds and your wallets. The first is by searching for individual wallet addresses on websites specifically designed to let you view all the transactions on a particular Blockchain. The other is to store a copy of your wallet contents on an application that tracks the prices of all cryptocurrencies. Blockchain.info is the block explorer for Bitcoin, and it allows you to track all wallet movements so you can view your holdings and all the historical transactions within the wallet. The Ethereum blockchain’s block explorer is called Ether scanner, and it functions in the same way. There is a rival to Ether scanner produced by the Jibrel Network, called JSearch which will be released soon. JSearch will aim to offer a more streamlined and faster search method for Ethereum blockchain transactions. There are many different kinds of block explorer for each individual crypto currency, including nanoexplorer.io for Nano (formerly Rai Blocks) and Neotracker for NEO. If you simply want to view the value of your portfolio, the Delta and Blockfolio apps allow you to easily do that. But they are not actually linked to your specific wallet address, they just show price movements and total value of the coins you want to monitor. That’s not all! You can learn how to transfer and monitor the funds in and out of your wallet by clicking on the link. To be continued!

Ripple wallet ledger app on windows 7(32bit) still not working!!!!
I had to sign up to reddit just for this one. Had the ledger nano s for a month and a half now and still can't get the ripple wallet to work. Its the app on windows that is failing not the app on the nano. Have uninstalled both apps numerous times, you uninstalled the app on windows loads, reinstalled the latest x86 updated app from github (20th december 2017) still no luck. I use to get the app to blank screen on me for the first week, which at the time seemed like progress but for the last few weeks it's just decides to open 3 instances of itself as displayed on the task manager, hogging up the cpu to 90% with no gui and then disappear. If you're gonna clone yourself at least stick around for a bit! this one doesn't work for me on windows 7 =setup_ledger_wallet_ripple_win_x86_1.0.3 neither does this one setup_ledger_wallet_ripple_win_x86 both the latest updated versions for windows. Funny thing is ripple is the most centralized decentralized crypto there is and its messing me around just like a bank or solicitor would. the irony! I thought ripple would be on point, not lagging behind the bitcoin,ethereum and stratis ledger wallet apps! its got nothing to do with turning browser support off,chrome open(or any other app including bitdefender=don't have it or antivirus/firewall as I have none or have it switched it off), usb cable,firmware(coz i've got the latest version). I've tried many, many times with basic system apps running , nothing else. The gui should load regardless right?I've been looking up this problem up for weeks and am thinking i'll have to get my xrps off binance and go down the cold storage usb toast wallet again. to be fair the nano ledger is just a special edition usb with a couple of "unhackable manual" click buttons. anyhow. any help much and really appreciated!
"1) I can backup my wallet by exporting a wallet.dat file. Do I have to do this everytime I receive more BBP? Or just whenever I add a new key? 2) How do I add new keys? 3) Can I generate and see the private key so that I can write it down/print it and store it somewhere safe?" -znffal 1) think of your wallet.dat file as your passbook in a passbook savings account. You have to have that .dat file to be able to access (and prove you SHOULD have access) to the BBP stored in your account addresses. Exporting it once is all you need. 2) Adding new keys? The passphrase (password) you use is the only "key" you would have in an encrypted wallet (besides the .dat file). If you mean new addresses, you can get those by going under File and Sending (or Receving) Addresses and hit "new". 3) Clicking Encrypt Wallet will be where you choose a passphase, I don't know you can see it other than when you enter it. To put a real world example or two. Example One: You don't ever encrypt or backup your wallet. If I borrowed/stole/hacked your computer, I could send all your coins to my wallet (no passphrase). Example Two: You encrypt your wallet with the passphrase "secret" but don't backup the wallet.dat file, then your computer crashes and you lose all your data. Since you didn't have a copy of the wallet.dat file, your coins would be lost. Example Three: You backup your wallet.dat but don't encrypt it. Your computer crashes and all your data is lost, but you re-download the QT program, restore your wallet.dat, all your coins are still in you wallet. But if you lose your USB drive that has the wallet.dat on it, and I find it, I can put your wallet.dat on another computer and send all your coins to my wallet. Example Four: You encrypt your wallet and back up the wallet.dat file. If I hack/borrow your computer, unless I guess your passphrase your coins are safe. If you computer crashes, your can restore your wallet.dat file to another computer and your coins are safe. In short, Encrypt your wallet (passpharse) and then backup (copy) the wallet.dat file to at least two locations." -616westwarmoth "Find your wallet.dat file, copy it to a flash drive or any other secure place. If your computer crashes, you'll always have the wallet.dat and can put it on a new machine. It will have to resync a bit when you do, but you'll never lose your "key" to the wallet. Speaking of keys, you should password protect your wallet and make sure to remember it!" "Yes you must have a copy of the wallet.dat somewhere. So multiple back up copies are a good idea. If you lose the wallet.dat file the coins will be in limbo but there will be no way to recreate the file. One thing to remember is it doesn't matter if the wallet.dat file is "current", it can be 10 years old on a flash drive and you can download a new client, put the wallet.dat file into the machine and you'll be good." -616westwarmoth "In addition to this, whenever you reboot the node after more than 24 hours of being synced, we back your wallet.dat up into the "backups" folder. This is useful if you ever accidentally delete your wallet.dat. Also, if you want a paper backup, you can do a 'dumpprivkey accountaddress' command from the RPC." -Rob "wallet is a collection of private keys" "there are other ways to achieve high security. You can make a new wallet, encrypt it with a long password, send coins to it, put it on a flash drive and put it in cold storage, then download the hard drive cleaning program and erase the wallet.dat sectors from your PC. And of course, keep a printed copy of the private key on paper and put it in a safe. Put the usb in the safe also. Burn a cd rom with the wallet.dat file and put it in the safe." -Rob How to safely back up your wallet https://dashpay.atlassian.net/wiki/spaces/DOC/pages/1867878/How+to+safely+back+up+your+wallet Keep Your Crypto #SAFU (CZ's Tips) https://www.binance.com/en/blog/421499824684900429/Keep-Your-Crypto-SAFU-CZs-Tips References: https://bitcointalk.org/index.php?topic=2042657.msg23955128#msg23955128http://forum.biblepay.org/index.php?topic=27.0https://bitcointalk.org/index.php?topic=2388064.msg27797529#msg27797529 To Read: https://en.bitcoin.it/wiki/Wallethttps://en.bitcoin.it/wiki/Storing_bitcoinshttps://bitcoin.org/en/secure-your-wallet NOTE: As of version 126.96.36.199 we have updated to HD wallets, so you should not need to worry about keypools anymore if you have upgraded "Regarding the Sanctuary, you receive payments always to the same address (key), so the keypool is not consumed for those payments. But when you click to generate a new address on the "Receive" tab, one key will be deducted from the keypool. Also, sometimes new addresses are automatically generated and the keypool is consumed, for example when solo mining and finding a block, a new address could be used for the block reward. You can always check your current keypool size by typing "getwalletinfo" in the RPC console and see "keypoolsize" and "keys_left". It's only concerning if they are a low number and you plan to generate new addresses in your wallet. They start from 1000. If the number gets too low, you can just type "keypoolrefill" to refill them back to 1000 and then you should backup the wallet. But from my experience the wallet automatically refills the keypool from time to time (or after certain actions like transactions), because I see that my wallet file keeps getting larger and the "keys_left" returns to 1000. The only issue is if you actively use your wallet on multiple computers (for example cloud mining or simply sometimes using the wallet on your laptop), then one wallet could refill the keypool with new addresses and the other one will not, or they will generate different new addresses. If I understand this correctly, for example, you could receive a payment on a new address generated in one wallet; your old balance will be there on both wallets, but only the one wallet where you generated the new address would show the new payment. Then you should copy the wallet.dat file to other computers, to update them. If you use the wallet on just one computer, you should just backup the wallet from time to time (or when you see it has increased in size). Qt also backups wallet.dat automatically, those can be found in the folder %AppData%\BiblepayCore\backups, you will see that they also have timestamps in their names and possibly different sizes." -inblue https://bitcointalk.org/index.php?topic=2388064.msg27391534#msg27391534
