1. Even if institutional money has been interested in Bitcoin, it wouldn't have waited for Bakkt or similar. It's have gone through via PE or just OTC, and that's probably already happened at least since 2017.
2. Even if people thought Bakkt was big, and these same people had any impact on price, then they've already made their sentiments known last year. Their buys would have been in position, hence, all priced in already
I think we can't make such claims yet
They are a little premature as the real effect will be seen and felt after the platform starts operating for real. As I've written before, it will trade real bitcoins so its impact on price will be direct via supply and demand. In this way, if there is a lot of volume at Bakkt, the influence on Bitcoin's price will be substantial. And due to this, we won't be able to say if it was really overrated as it could actually turn out that we might in fact have been underestimating it
Maybe you will end up being right after all. If that happens, I will be the first to look.forward to increased price pressure when Bakkt dips in every now and then to get Bitcoin to settle.
Just wary that almost every significant event has long been priced in, as can be seen even from the bch split and halving. In theory, Bakkt launch, halving coming up, this should be causing glut in demand.
