And then I wonder why a creator of the system only delegates 250 himself when he has much more? He asks people to delegate as much as possible yet only delegates 250 out of his 599 (not counting the liquid steem he has). If he only had 599 I could maybe understand. But he has 2000 delegated to him.

Well if I would create a system and want to promote it I would delegate practicily everything I could.
