What Is A Cryptocurrency Exchange?
An exchange is an online service where you can buy and sell various cryptocurrencies.
Their services vary greatly. Some exchanges only support Bitcoin or a handful of the popular coins, whereas others support a range of altcoins.
Please make sure you also read all of the terms and conditions of any exchange you use, and review the fees charged. There are several different models that exchanges use, so it’s important you understand where fees are applied. Experienced users do not typically store their cryptocurrencies on the various exchanges and trading platforms, except for when they’re actively trading. Most use a hardware wallet, read more about wallets here.
