There are several ways to buy and sell cryptocurrency. You can buy or sell cryptocurrency through a crypto exchange, or you can use a peer-to-peer (P2P) trading platform. Crypto exchanges are typically more secure and offer more features than P2P platforms, but they often require more verification to get started. Once you have an account setup on either an exchange or a P2P platform, you can typically buy and sell cryptocurrencies with the click of a button.
