Have started trading some of mine at https://poloniex.com/ . It is now linked from the Transfer option on the STEEM wallet. Of course it is owned and operated by Justin Sun if that bother you. Until recently my HIVE has been traded for XMR on @blocktrades regardless of my thoughts about Dan Nostein. It's only business. 😎
P.S. Have been placing 2500 satoshi orders which seems to spike to that price at least weekly.
Thanks for this - will take a look, below Steem-engine is something am looking at at the moment :) thanks so much for taking the time!
