Oh I have no doubt they're getting involved because they see it as a threat. Unfortunately, as with many things, there's not much we can do about it...they'll do what they're gonna do.

Someone mentioned in a post I read recently that there was a huge amount of short interest in BTC right around when it was testing the critical support level near $6k and I would be willing to bet a decent amount of that was traders that work for JPM / other investment banks and their ilk.

They move / control much larger markets than crypto (think commodities like gold and oil) so they have enough firepower to move the price of any given crypto around as they please if that's what they truly want to do.
