How can I reclaim my Bitcoin Cash from my Greenaddress wallet?
Unfortunately, if your wallet/exchange does not support BCC, then you have probably forfeited it i.e. left it to their disposal. The only way to find out would be to message their support and see if it is supported. If it is, you will automatically have a balance of both. There are a few exchanges supporting BCC trade including bitrex.com (or have a look at coinmarketcap.com &rarr;     Bitcoin Cash &rarr;     Markets)
