The price of bitcoin doesn't move an inch based on futures gambling, because no bitcoin exchanges hands. And most of these bankers don't even own any bitcoin (and don't care to). The current bitcoin explosion, starting 29th of November 2017, was started by by a flip-tradebot with many bitcoin in possession. What it's doing is draining all the other coins on exchanges, and pumping that value into bitcoin. Rinse and repeat until people pull out of the altcoins and buy bitcoin just to get stuck with it in their wallets because there is an endless backlog of transactions on the Bitcoin network.
