I asked, Guotai Junan International and Futu, the current plan to enter the cryptocurrency space is still through brokerage intermediaries, with Hashkey being used at the bottom layer.

Guotai Junan International requires users to hold a long-term overseas visa.

Futu requires users to have a Hong Kong or overseas ID.

If a cryptocurrency user runs from Binance to register an account with the above, it means they not only need overseas identity documents but also have to deal with the tax system, effectively going back in history.
