What is a cryptocurrency exchange?

Cryptocurrency exchanges are websites where you can buy, sell or exchange cryptocurrencies for other digital currency or traditional currency like US dollars or Euro. For those that want to trade professionally and have access to fancy trading tools, you will likely need to use an exchange that requires you to verify your ID and open an account. If you just want to make the occasional, straightforward trade, there are also platforms that you can use that do not require an account.
