I'm not surprised that BTC dumped after the news. It's just like back in 2017, when CBOE and CME launched BTC started falling all through 2018.
I won't be totally surprised if history repeats itself.
That news had nothing to do with that dump, do you and some others can start reading that almost identical things have been going on for months. You also mix BTC futures back in 2017, their effect was enormous and it pump price to $20k, with huge media FOMO of course. But it was time after halving, now we are in pre-halving time, and Bakkt can only help to boost price.
History repeats itself, there are some patterns that we can follow through Bitcoin history, but 2020 does not fit that pattern. After long crypto winter and recovery, we are now moving towards a new achievements, price should go up, not down.
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..
