You did just right. If you have noticed in your transaction, there has a message for you regarding the fees. It usually is higher than any other market. But the good thing about Blocktrades is that it decreases its fee depending on how much sbd you transacted using blocktrades. Mine was 2.5 something when i started using blocktrades. Now after 5 transactions, the fee is down to .5. Hehehe Hope to have another way to resolve these issues on transactions. One potential solution is Bittrex. I just hope they'll accept new users prettty soon. hehehe
