This is good news. It means it's being invested and held long-term in the platform, rather than being cashed out. That's something that some people, I think, miss when I try to explain the system to them and they chalk it out as a pump-and-dump. Steem Power is not liquid and can't simply be traded off. Dan and Ned are in the same boat as everyone else if they were to try to dump all of their stock and sell it for profit. This is encouraging, to see more people investing.
Guess that means I'm on the right track with powering up myself :D
