This has been said for a long time now. Does anybody really believe that there is a thing called as "institutional FOMO". Institutions don't FOMO, they create and guide the conditions that lead it it.
I will also not call it institutional fomo because institutions do not just invest but analyse very well about bitcoin before investing. I believe some institutions are ready to join but their analysts are advising them to wait until people will fomo which will be around next bitcoin halving.
When we talk about institutions, we aren't talking about companies owned by people like Musk, Saylor or Jack who are into Bitcoin because they believe in it. When it comes to wide scale adoption, there is no escaping the "institutions". They will leave no stone unturned to ensure that crypto does not become some sort of safe harbor for the billions of "consumers" on which whole economies depend. As far as capitalists are concerned, Saving is bad for them.
Michael Saylor do not just believe in bitcoin, his company Microstrategy is actually a bitcoin institutional investor, if his company sell all his bitcoin holding today, the price of bitcoin will fall not only abruptly but also significantly. I do not know if Jack Dorsey have any institution investing in bitcoin, I only know of square and the decentralized exchange he is planning to create. Elon Musk, that man is a manipulator, he is not a friend to bitcoin, I do not know yet if he has sold his $1.5 billion bitcoin but he bought it not as an institution, also Tesla dump bitcoin for doge which he manipulated.
More institutions are looking towards 2024, next halving. I guess this but that period, 2024 to 2025 will likely be very bullish and not only retail investors that will contribute but also institutional investors.
