An earlier than planned release will catch a lot of traders off guard. They will probably try to play the pump and dump game where they buy the rumor and sell the news. Hopefully this will be released soon to avoid price manipulators from cashing in
There is no buy the rumor sell the news in this case, simply because the market doesn't seem to care about Bakkt.
In the end, most participants currently have bought coins already, or have been forced to hold their bags during this bear market; there is no buying happening that will steer the market higher based on these developments. In other words, we're left with sellers mostly, and as soon as the price climbs back up, they'll help dump the price back down to where it started.
Keep in mind that Bakkt doesn't buy spot coins, which is what people tend to overlook, so there is no reason why the price should go up.
