Institutions hold nearly half of the total Bitcoin, but it does not mean that nearly half of the institutions hold Bitcoin!
Currently, well-known investment banks that hold Bitcoin are still rare, and they may hold it on behalf of their clients. For example, JPMorgan Chase holds $1.16 trillion in US stocks, but only holds $760,000 in Bitcoin spot ETFs, which is less than one ten-thousandth of its asset management scale. (The market value of Bitcoin is very high. I personally think that Bitcoin has the potential to double, and the rise and fall is weaker than other cycles)
