I don't think so because the CME product will based on the prediction and there is no direct buy to the bitcoinmarket. i just like use the bitcoin price as the main pegged of the contract. and there will be no buy to buy into the bitcoin market. It will not give any manipulation to the bitcoin.
Yes, I think that too. That is a future what I have heard of, and thus they should not interact on Bitcoin.
But still, someone very wealthy could predict a price and put all his money to make it happen. Bt that can happens in any market.
