Are there any exchanges that allow it? I heard Bitfinex does, but also heard that they only allow conversion to USDT (and people were having trouble converting USDT into USD, unless this has been solved?)
BCH has been added to the coinbase but still they not add the features of buying and selling,I hope they wipl add this feature soon.So you can move your BCH to coinbase then sell it for USD.But I think ot is not a good time to sell BCH because the price keeps increasing so you just hold it for few more days to get extra benefit.
