The peg is jus half a peg, what is kind of useless. Now would be the chance to introduce a peg in the opposite direction and make SBD a truly suitable services coin. I'dd propose allowing for a bit of bandwidth between upward and downward pegging and as we already have the $1 downward pegging, adding a $ √2 upward peg.
An other thought is, with the current looming trade wars, is the USD really the most logical fiat currency to peg against. It might be a good idea to look at a different currency, euro or yuan maybe, or better yet, peg it to silver. The most essential thing though, make the peg a double one with a realistic bandwidth between the upward and the downward pegging.
If we ever want to regain the promise of a services based economy, doubly pegged SBD is truly the only way.
Just made this blog on the subject, arguing for a quadrupal peg. Think it's relevant to this discussion.
