I think these institutions will not hold BTC for long, as long as they are profitable they will leave, perhaps then there will be a sharp decline.
But think about it, why Elon Musk and others large institutional investors are starting to invest in Bitcoin today instead of doing it last 2017 bull market? There could be some reason about it but why should I care when I am just a small fish in the sea compared to these sharks.
If they do leave out the market then let them be because it will just eventually recover no matter what.This is one of the cons when there are people/instutions/companies
who do baghold much number of coins because of their financial capacity which is really normal or anticipated.
