As far as building working products and an eco system on Steem, I'd say there is much more benefit to having a stable price (somewhere way above where it is now of course) but not one being pumped and dumped by speculation.
However we badly need a huge marketing drive around forthcoming communities and SMTs as these features look to be revolutionary and far too few people, even in the rarefied world of crypto today, even know they're coming here.
