This may be of interest to HIVE users wanting to trade their STEEM for HIVE. However purchase of HIVE is mostly on 
However Bittrex doesn't have deposits of STEEM open yet... but you could trade steem on binance for BTC and then transfer over to Bittrex. It's more complicated than it should be, I understand.
Also it would of course be nice to have HIVE also listed on Binance.
But what i'm really looking forward to is the SBD and HBD they have on Bittrex that will be very handy.
