My personal strategy with STEEM is to go against the tide. So when I see that people have stopped powering down and the market has reversed, that's when I will probably start to power down. That wouldn't be the only factor; the price needs to be bounce back high enough to make powering down of interest to me. But for now, I'll let everyone around me power down and continue to keep and grow my VESTs. I know the Steemit team is in it for the long haul and I think they have a solid vision. They could really use a PR manager though.
