I was wondering what if someone accidentally sends Bitcoin Cash to a Bitcoin address?
I saw a post in twitter from one of the staff I think of Bittrex that they will not do anything if anyone accidentally sent BTC to a BCC wallet and vise versa. So better be careful in sending those funds and double check the address if address is correct. Don't even bother to open a ticket according to the post. Its irreversible for now. I am not sure with other exchange sites.
Not only Bittrex exchange, any exchange have pair BCC are warning be carefully before sending Bitcoin Cash to their Wallet, if user have mistaken, they can't helps this user and this amount will loss all.
