The seven things to consider before choosing a cryptocurrency Exchange

If you decide to choose another cryptocurrency exchange, here are the 7 things you need to consider:

1. Check that the exchange is available where you live

Exchanges are not all open to traders all over the world, so that might be the first thing to consider.

You have to check that you are able to register on any of these platforms.

2. Consider the nature or type of the platform

There are several types of cryptocurrency exchanges:

  • Trading platforms: they connect buyers and sellers and collect a fee from the transactions that are made;
  • Direct person to person trading platforms: they make it possible for people from different countries to exchange currencie

3. What currency does the cryptocurrency exchange accept?

In order to buy the Bitcoins or Altcoins that you desire, you will need to charge your account with some currency. Is it euros, usd, or other cryptocurrencies ? Exchanges do not all accept what we call fiat currencies (eur, usd), some only accept other cryptos (bitcoin, ethereum,..).

4. What mode of payments does the cryptocurrency exchange accept ?

There are a variety of ways you will want to charge your account. Paypal and credit card are usually popular and in high demand. Bank transfers are another common method.

5. How reputable is the exchange you are considering?

Reputation is key. The world of cryptocurrency exchanges is sadly full of scammers or unreputable platforms. Choosing a cryptocurrency exchange that has a good reputation is essential. That reputation will be a combination of different things:

  • how long has the exchange been existing for?
  • who is it backed by, who are its shareholders or promoters?
  • where is it established?

6. The issue of security.

The Bitcoin protocol has never been hacked, but there have been many cases of hacked exchange platforms: MtGox, Bitfinex, … So you need to be aware that 100% security doesn’t exist, that most of the large exchanges are working hard on security, and that what you really need to do is avoid the rather shady scammy platforms. My recommendation: stick to the big names.

7. What kind of storage does the exchange offer?

Once your cryptocurrencies will be on your account, there are different ways they can be stored by the exchange. It is something important to consider because some exchanges offer interesting security features.

Once you have considered all this, you can decide to go through this list of exchanges by, it will give you the highest trading volumes by exchange in the last 24 hours, so depending on the currency you want to trade you can see which exchanges provide the best liquidity.

Have a safe crypto trading !
