That is just futures and if we have seen enough of the futures so far and how they affect the prices of bitcoin I think just futures would be really scary for all of us. Even with bitmex that is basically our own we are still seeing a lot of people betting on bitcoin going down and whales spending millions of dollars into short futures and trying to keep the price as low as miners allow them and try to make as much money from it as possible.
Futures are creating a conondurum which allows rich people to both sell bitcoin (create capital for themselves) and at the same time buy short futures with that same money and make double the income. Whereas if they want to make money by buying long futures they would have to both buy bitcoin to increase the price (costs capital) and buy long futures at the same time (costs capital as well) which means they need to spend double the amount for probably even less profit.
These futures are physically delivered and not leveraged. Which is entirely different than the futures from last December. Here they will actually be receiving Bitcoins, instead of just making bets on the price. Also futures is just the first product, I'm sure it won't take too long for them to introduce actual Bitcoin trading on BAKKT.
