What is an exchange?
Cryptocurrency exchange websites and mobile applications allow users to buy, sell or exchange digital currencies for other assets, such as fiat (GBP, EUR, USD, etc.) or other cryptocurrencies.

Main types of cryptocurrency exchanges
There are countless types of cryptocurrency exchanges offering different coin options with higher and lower trading volumes, different platform features, and different security measures. To diversify your trading as much as possible and reduce the risk of account hacking, it is worth holding the currency on two or three different exchanges at the same time.

There are also a number of different models of cryptocurrency exchanges. One of the differences is whether you can use fiat currency to buy the cryptocurrency you trade on the exchange, and whether you can convert your cryptocurrency back to fiat after closing positions.

Best Centralized Cryptocurrency Exchanges
The most famous and largest exchanges, as a rule, are centralized. These include Coinbase, the largest of all cryptocurrency exchanges by number of users; Binance, the largest in terms of trading volume, and Gemini, another major competitor in this space. Centralized exchanges are especially popular with novice crypto investors as they tend to be more intuitive and more likely to offer dedicated 24/7 support through various social channels and chat.

Another factor that makes centralized exchanges suitable for beginners is that they take custodial responsibility for storing your private keys. This is generally much safer than storing data on your personal device, as exchanges spend millions on cybersecurity to keep your personal information intact and safe. A forgotten seed phrase or a missaved address can mean the irretrievable loss of all your holdings, so many newbies find peace of mind by transferring data storage responsibility to a large, reputable, centralized wallet.
