Have you included @blocktrades in any of these talks. I would hope this is something he's thought about or at least looked into. I don't know with regulations if this would be something he would want to take on, but with the ability to trade Steem for other cryptos I just assumed he would add the ability to trade Steem for SMTs.
Also, there are a lot of talented individuals in the community. Maybe it would be easier to set-up a bounty of some sort of the creation of an exchange that could handle this built by the Steem community. Probably hard to start building for something that doesn't exist yet, but think it would be possible to at least start on the foundation.
We haven't talked with @blocktrades yet because I thought they're more like a converting service instead of an exchange so they only list tokens once it's tradable in exchanges and have market value already.
I guess we can do something together with @blocktrades if they have plan to expand their business area.
Thanks for sharing your thought :)
