7 day payout vs evergreen payout is a feature , which if appears to be critical can be implemented / cloned from ONO.
In my humble opinion , a stronger signal ( atleast for me) would be if one of these projects starts getting eyeballs/engagements even at 1/2 the levels of steemit , if/when that happens it would be time to seriously look into one of these projects.
Till then , I am holding my chips..
