Hive account@blocktrades still new on steemit so am not sure i understand how these things work yet.

I transefered 0.438SBD to blocktrades to be converted to BCH in my coinbase wallet BCH address. The transaction was completed.. As it shows on both my steemit wallet and on my blocktrade account but i cant find any BCH on my coin base account and the SBD is no more on my steemit wallet. Please do something
