Provided that you‘ve read the previous two articles in this section you’ll know what a crypto wallet is, how to set one up and send/receive cryptocurrency. In order to buy cryptocurrency - the next logical step - youll need to first create an account with a Cryptocurrency Exchange.
Introducing the Crypto Exchange
Buying cryptocurrency is similar to buying foreign currency for a holiday. It is just an exchange of one currency for another at an agreed rate - e.g Euros for BTC (the currency symbol for bitcoin) - which is why the most common place to buy cryptocurrency is called an Exchange. It may sound confusing when cryptocurrency like bitcoin is talked about as having a price, whereas for dollar, euro etc we are used to talking about an exchange rate.
These two terms - price/exchange rate - are interchangeable and simply reflect the fact that currency values - especially crypto - are constantly changing.We move into why that is in our section on Trading, but for this article,it is simply worth knowing that the price of cryptocurrencies like bitcoin doesnt come from a single source.
The price simply through back the interaction between buyers and sellers on each Exchange, which organically maintain parity with each other. (again explained in detail elsewhere). An above all representation of price can then be reached by aggregating the price from the main exchanges.
Choosing an Exchange
As cryptocurrency is becoming popular, this resulted in increase in the number of exchanges to choose from. You'll find that even the most credible exchanges struggle when demand is particularly intense, so try and plan the process of choosing an exchange, rather than reacting to the next big price rise. To make that decision easier we have summarised the key criteria and main operators, before providing a walk-through of what the first-time buying process will involve:
Given Security the priority most should always be your consideration in choosing an exchange. A quick Google search would, for example, establish if an exchange has ever been hacked, experienced significant downtime or has been subject to any legal sanction. A part from the security of the platform itself, look into how seriously they treat customer security and your personal data.
Especially for newbies in to Cryptocurrency, it is advisable to choose an exchange that is focused specifically on helping you buy for the first time with ease. This means simple layouts and a great mobile experience. Stay away from exchangers targeted at experienced traders. This should be obvious from their home page, where language should be simple and understandable with a clear focus on first-time buyers.
As we will discuss In the next article, exchanges targeted at beginners will boil the buying process down to just a few clicks, just like a normal online purchase process. This removes a lot of the pain of buying crypto, but does compromise on the control you have over the exact price you buy it, and the fees you pay. Some exchanges cater to both newbies and pros with separate products e.g Coinbase and Coinbase Pro. Make sure you are using the basic service as the Pro site will assume a significant level of understanding.
An exchange works as a go-between, matching people who want to buy with people who want to sell; they charge a fee for facilitating the exchange. The size of that fee is calculated as a % of the amount you buy or sell. Therefore as you are trading to make some profits, fees should be a key consideration in your choice if you are intending on making a significant volume of purchases. If you simply want to dip a toe in the water then fees will be less significant.
Choice of cryptocurrencies
When it is your first time buying cryptocurrency , the likelihood is you are buying bitcoin or ethereum. However, Should you, have a specific alt coin (alternative coin) in mind, or think it likely you‘ll want to diversify, make sure to choose an exchange with a broad enough range of cryptocurrencies. The are literally thousands. The process exchanges use in adding differing cryptocurrencies varies greatly, so you’ll find a big difference in the availability. If you want to trade a niche crypto, check its availability in advance.
One of the major factors in your choice should be based on how much the exchange is tailored to your local needs. Is the site translated？ Does it provide relevant local payment options？ Are there country restrictions specific to where you live？
Make sure to use an exchange that is trustworthy Buying cryptocurrency is exciting and empowering, but isnt without risk. . Referrals from friends are a good practice, as is researching on Google, App Stores Social Media and Reddit. Avoid promoted reviews and try to find genuine opinions.
How an Exchange Account works
Even though cryptocurrency itself is decentralised - as explained in our basics of cryptocurrency section - the standard model for exchanges is a centralised one, which is why you‘ll see the acronym CEX - Centralised Exchange. This is a big point of debate within the crypto community because using a CEX is a custodial option - remember ’Not your keys, not your coins.
As part of the process of creating an account with an Exchange you automatically get a web wallet (jump to this article for more information). This is like an online bank account or App where you can check your balance in fiat (Euro/Dollar etc) which hopefully increases over time. Any cryptocurrency held in your new exchange wallet is in the custody of the exchange which is why Security should be a huge consideration in the process of choosing an exchange. Ensure you follow best practice for securing your exchange wallet is also crucially important.
Your cryptocurrency exchange wallet will allow you to do the following, which were discussed in the previous article in this section:
Send your crypto to another person/service
Receive crypto from another person/service
The trading features of your cryptocurrency exchange account will allow you to:
Convert your crypto for other available currencies
Sell & Withdraw
We will all discuss these in our next article.
Centralised vs Decentralised
As mentioned above, the most common model is a Centralised Exchange (CEX). But The main reason for this is that in order for an Exchange to sell cryptocurrency, customers need to deposit regular (fiat) money from a bank, credit card or e-wallet - all centralised and regulated financial services.
Because of this , the majority of exchanges are centralised, regulated businesses, with servers located in specific countries where they abide by the appropriate regulations for financial services. They have visible management teams and 24/7 customer service. In fact youll soon be able to buy shares in Coinbase the same as Facebook or Apple.
As explained earlier, using a CEX also means they custody (look after) your crypto until you decide to move the funds to a non custodial wallet. For those unwilling to compromise there is another option the DEX (Decentralised Exchange). As the name suggests, decentralised exchanges aren‘t located in any one location and don’t follow a traditional account based approach.
Instead DEXs facilitate access to liquidity (buyers & sellers) via applications that themselves are just smart contracts, with no specific geographic location and therefore, can‘t (right now) be subject to any set of regulations around things like KYC. Using a DEX means you are not only responsible for custody of your funds, but there is a lot more you’ll need to understand in order to buy and sell.
Usability and complexity make DEXs inappropriate for beginners but even more importantly a DEX is crypto-to-crypto only. If you are a crypto virgin your first purchase will involve you using a fiat payment method meaning a DEX is out of the question.
Person-to-Person Exchange (P2P)
The standard CEX model takes most of the hard work out of buying crypto as you never actually have any idea of who you are buying from. There is, however, an alternative type of exchange where you can interact directly with a seller (or buyer) of cryptocurrency - called P2P (peer-to-peer).
This approach is a bit like eBay, where you can sort vendors by:
• Price they are willing buy/sell at
• Terms of sale
• Their reputation
• The payment methods accepted
The most popular P2P Exchange is Localbitcoins, available on a country-by-country basis following a regulated, KYC approach. As with the DEX, using a service like Localbitcoins isnt recommended for a first-time buyer simply because the process is too complex.
Aside from being active to choose who you want to buy from, also you will have to be comfortable sending funds to a trader and then navigating an ESCROW process whereby funds are held until you receive your bitcoin. P2P exchanges like Localbitcoins provide a valuable service but should only be considered once youve got some experience under your belt.
Rather lets go through the process of buying from a CEX that is designed for first-time users like you.
