Hey Steemit, please send help!

I made the mistake of transferring SBD to my coinbase (BTC) wallet. Given that coinbase doesn't accept SBD at the moment, there is no transaction showing up in my wallet. However, the transfer was completed through @blocktrades ... so I'm wondering, what the heck happened? It would be a shame if I lost my money.

Has anyone else done this on accident, yet? I'm at a loss right now.
