How to Sell Bitcoin
These days, virtually every method available to buy Bitcoin also offers the option to sell it, with the exception of the Bitcoin ATMs, though some allow the exchange of Bitcoin for cash, but not all. Coinatmradar can help you get to the closest bitcoin ATMs in your area.
The type of exchange you choose to use to sell your bitcoin depends on what kind of support they offer: small investor, trader or institutional support. Some platforms like GDAX and Geminis search for the larger orders coming from institutional investors and traders, while retail customers can sell on the Bitcoin stock such as Coinbase, Kraken, Bitstamp, Poloniex, etc. Every currency has a different interface, and some offer related services such as safe storage. Some of them require a verification to identify all operations, while others are more relaxed when it comes to small amounts.
Another alternative is direct sales. You can register as a seller on platforms like LocalBitcoins, BitQuick, Bittylicious, and BitBargain; interested parties will get in touch with you if they like your price. The transactions are performed through deposit or wires to their bank account, after which it is expected that the transfer of the agreed Bitcoin amount arrives to the specified address.
