I couldn't have said this better myself, and I think this should be highlighting the real reason we shouldn't be doing anything funny like reverse conversions.
I keep wanting to say, STEEM doesn't deserve to have SBD be stable yet, but that doesn't sound right haha.
I also doubt that the SBD price is deterring stores from flocking to adopting SBD. And even if they wanted to, stores should just use market prices for accepting currency anyway. Just like how it would be for any other crypto...
