Don't forget to mention the fact that bakkt futures are settled by real btc, all the other were only settled by cash. As more traders are trading on bakkt, as more futures bakkt has to hold in their wallet. so it could have an big effect on the price of btc..
It goes both ways. It'll be very interesting to see what it does after another bubble pop. Most will want to switch to shorting for dollars in that scenario, that's if they were ever interested in physical BTC in the first place.
