I honestly think that the Bitcoin volatility is here to stay for a very, very, very long time no matter if pumps or dumps. The crypto market is still small and young, so there is a lot of room for Bitcoin and other cryptocurrencies to grow even further as institutions are starting to buy Bitcoin from all over the world. I also believe that only less than 0.01% of the institutions worldwide are buying it, and there are still a lot of them who are not yet aware but may be gaining interest later on.
What you have posted is correct. But investment from institutions are very susceptible to regulatory action. We all saw what happened to XRP, after the SEC acted against it. The same would happen to Bitcoin if they take a similar stance against that coin as well. For now, everyone is ignoring this risk factor. But it is like the sword of Damocles, always hanging over our head.
