You can sell Ripple on several exchanges, the most popular of which include Bitstamp, Kraken, and Gatehub. To sell Ripple, you will need to create a sell order on the exchange by entering the amount of Ripple you wish to sell and your chosen price. The order form will also ask for your wallet address to deposit the exchanged XRP into your account. Alternatively, you can also sell your Ripple for cash by selling it to a friend or family member. Finally, you can also use a peer-to-peer exchange such as LocalBitcoins to sell your ripple for Bitcoin.
