I just tried to transfer some steem dollars to my new coinbase account for the very first time. I got an address from coinbase, put it in blocktrades, got a memo, transfered the money on steemit, and waited and then got this:
What did I do wrong?
[EDIT]
Fortunately, the money got refunded after a while with a memo "refund by admin" and I could try it again. This time I selected "Steem Dollar" instead of "Steem" and everything went well.
