As long as you believe in a project and is developed, the position doesn't really matter. I'm full bullish on getting 10K SP locked in for a LOOOONG time @cyberblock.
If each users starts powering up instead of bringing out each little reward got from spam posts, the STEEM value will naturally rise with positive pressure from low liquidity.
It's been falling for two years though compared to other coins. Did you know that steem use to be in the top ten? lol
