Except... you still haven't explained *why* they need to buy those coins from the exchanges for $5. Then they will be accused of price manipulation and owning 100% of the coins in existence. Just more fodder for what you are trying to do here.
So the hypothetical $7.5M out of GAW's pocket is the price they pay *not* to look like they are manipulating the coin?
Are you serious? You think they have to buy all 500K coins at the end of POW? Some will go to other exchanges, some will get staked, some will get home wallet staked, some will get cashed.
You don't think GAW has run these models?
