Steemit wasn't even that successful in the first place, the only ones thriving that community are part of circles jerks and groups of thousanda of followers that even if you are a good author you still won't receive the recognition you want. Hive will be the same as well, the ones who will migrate there already have established their bases and they will continje to thrive. With a small group benefiting from such project I really wouldn't expect much for its price since they are the only ones earning real money in the first place.
