Exchanges
Despite having several disadvantages, exchanges are a one-stop solution when it comes to trading Bitcoins. In the case of selling the cryptocurrency, exchanges act as an intermediary that holds both seller’s and buyer’s funds.

Direct trades
Another way of selling your Bitcoins is via a direct trade with another person. This service is accessible on websites usually associated with exchanges and includes an intermediary facilitating the connection.

Online P2P trading
Peer-to-peer trading marketplaces are a relatively new development in the Bitcoin world. There is no direct exchange of funds taking place. Instead, those websites essentially work as a platform that brings people with different, yet complementary needs together.

Via ATM
Despite looking like traditional cash machines, Bitcoin ATMs are not ATMs in the traditional sense. Instead of connecting to the user’s bank account, they are connected to the Internet in order to be able to facilitate Bitcoin transactions.

Selling Bitcoin in person
In many ways, trading digital currency in person is about as easy as it gets. All you need to do to sell your Bitcoins is scan a QR-code on someone’s phone and receive cash on the spot. If you’re selling to friends or relatives, you only need to set them up with a Bitcoin wallet, send them the necessary amount and collect your cash.
