Conspiracy theories again, I really can't understand you people. Every time when the price goes down some dark forces are to blaim and it's funny how we don't see such theories when the price goes up.
It's just price correction that is part of volatility process and probably conditions on.the market that lead to this correction. For some longer period of time we had relatively stable price then slight rise and now it droped. And this has also nothing to do with launching of Bakkt, it's just time coincidency.
