As an individual small investor, you can not buy Bitcoin Spot ETFs directly. You will have to work, sign contract with middle companies to buy Bitcoin Spot ETFs.

Those companies that submitted Bitcoin Spot ETF applications and got approvals, definitely have to follow existing strict laws and regulations in the USA. We know that country is very strict against Money laundering through cryptocurrencies.

Those companies will not allow you to invest to their business privately and you will have to do KYC to join.
