Just a quick word of advice, trading Steem at 
I was unlucky enough to be amongst the last users to try to exchange some Steem, of course the transaction failed and they still have not worked out a fix for it!
I have been waiting over a week for my refund, but still nothing. I do think they will send it back as they seem like a serious company, however waiting 6 days for a simple refund is crap!
Best way to trade Steem at the moment is Bittrex and Poloniex.
