Selling Bitcoin Cash (BCH)
If you wish to sell some or all of the Bitcoin Cash (BCH) in your Bitcoin.com wallet you will need to open an account at one of the many exchanges listed here which accept it. Next, send your Bitcoin Cash to the exchange's deposit address (which you will usually find in the 'deposit' section of your exchange account), sell them on the exchange and then withdraw the fiat currency (Euro, Dollar, etc.) to your bank account.
If you have any questions about selling Bitcoin Cash (BCH) on the exchange's site, then you will need to contact their support team for help.
