It's nice to see a user with a self built account pointing this out and not just the ones making money via delegation and votes. I have not been around all that long and it is a big learning process.
I have been buying some of my Steem via exchanges to help myself grow faster but every time I look at a bigger players account they are powering down. Doesn't it keep more value in Steemit to delegate to others for money than to power down and sell your steem?
