That's a super legit point and I think it falls under one of my mentioned "reasons not to buy". Although if you think about previously how much Steemit was selling of steem beforehand I would say DAO is a fine alternative.
There's no way I would leave my money at the mercy of Justin. I could, however, imagine taking some of my Steem and reinvest it into let's say BTC or ETH.
Yes DAO for us the only alternative I think! Sell pressure though... lots of sell pressure!
