That would definetly be something you should worry about if i was selling the tokens. but they are just a method of distributing rewards. so like lets say the top holder wanted to withraw his tokens... It's going to be like 70 steem or whatever the highest holder is. Now do you think im going to close shop and powerdown just because of 70 steem? hell no i owe so much thanks to that guy for delegating and putting his trust in me =)
