Are you honestly suggesting that at absolutely no point in time, any large institutions which were investing in bitcoin looked at the price charts prior to the last year and realized that bitcoin is prone to big swings in price?
Of course they knew about huge volatility. BUT, Bitcoin was being advertised to institutions as now more stable, DIGITAL GOLD, INFLATION HEDGE, and that the huge crashes were a thing of the past.
That narrative is now dead. It would take a very long time for institutional money to trust Bitcoin as being stable again...
