Cryptocurrency is becoming more and more popular. New types of digital money appear almost every day, and there are dozens of platforms where you can exchange one cryptocurrency for another, or even for real money.

Some of these platforms are peer-to-peer markets, where users make deals directly with each other, and the terms are individually discussed in each case. The system can be somewhat convenient for one-time operations, but absolutely not suitable for trading, partly because the choice of cryptocurrencies available is usually really poor: most often, it’s just Bitcoin (EXANTE: Bitcoin) and ether (ETH/USD). Therefore, as the market grows, more and more transactions are conducted through dedicated cryptocurrency exchanges.

The main risks for an investor who uses cryptocurrency exchanges are their possible bankruptcy, hacker attacks, and fraud (sometimes on the part of the exchange itself). At the moment, the exchanges do not provide any legal protection, so it’s unlikely you will ever see your money again in each of these cases. That’s why security is probably the most important criterion for choosing an exchange platform.

If you wish to make deals anonymously, you should understand that cryptocurrency exchanges are still subject to the legislation of the countries they are located in. This means that sometimes you will have to disclose your personal data when withdrawing your funds, and in some cases even when buying or selling cryptocurrency. Besides, most governments seek to strengthen the market regulation, creating special rules for trading in cryptocurrencies.

When choosing a stock exchange, one should take into account its trading limits, commissions, security and anonymity issues. Below you will find an overview of the world's top five cryptocurrency exchanges in terms of trading volume.

Five criteria for choosing a cryptocurrency exchange

  • Do not neglect safety. Often when an exchange can offer you beneficial terms, it is precisely because they save on data protection. However, low fees do not justify losing all your money in case the exchange is hacked.
  • Pay attention to the reputation of the exchange. If the exchange is large enough, fraud is less likely to happen. If you are planning to trade on a small exchange, carefully research its users' feedback.
  • Follow the news. If you receive timely information about a major hacker attack or come across comments on Reddit about problems with transactions, it will help to react and withdraw funds from the exchange before it’s too late.
  • Pay attention to jurisdiction. Some countries, such as China, are going to start regulating cryptocurrency exchange, and new rules may not suit you.
  • Decide what and how often you will trade. Exchange fees and withdrawal conditions may vary depending on the transactions volume and currency pairs, so it is worthwhile to determine in advance what you are going to trade and then to look for the exchange that suites you the most.
