According to River statistics, the current Bitcoin distribution looks like this:
Individuals: 13.98 million (66.6%)
Companies: 1.63 million (7.8%)
Funds and ETFs: 1.44 million (6.9%)Governments: 435,000 (2.1%)
Satoshi: 968,000 BTC (4.6%)
Lost Bitcoin (estimate): 1.62 million (7.7%)
Remaining to be mined: 919,000 (4.4%)

Bitcoin is becoming increasingly concentrated in ETFs, making the risk of custodians being hacked more and more serious. There aren't many of them: Coinbase Custody, Fidelity... A hacker could make a lot of money.
Perhaps that's why laws are
being considered in the US, which, if I understand correctly, will further break up the custodian monopoly?
And lead to greater deconcentration of Bitcoin in the ETF space.
