If you are going to list an item on this site, you should also list it on OpenBazaar as well. I believe OpenBazaar down the road will have integration of Shapeshift or something like to to go altcoins, the devs are not against these things, and in fact I am pretty sure some of them have Steemit blogs right now. I would love to see some Peerhub current sales numbers for Steem users.
