id be interested to know if it would make a difference to amount of people currently keep their hive on exchanges and what would that mean.
Blurt has a higher interest rate. (think it comes from both authors and curators pie) not quite sure of ROI but made it easier to just delegate stake out to someone who posts and curates there.
Most of the HIVE is sitting on exchanges, we can see that from the pablo reports every day. This would involve powering up that HIVE, which makes it non-liquid and susceptible to that 13 week power-down.
I think @blocktrades indicated that shortening this is not on the agenda, though it's not been a bad move for STEEM.
