The domestic lifting of restrictions still has a long way to go. Currently, one of the possible ways to achieve this is through the "Hong Kong Stock Connect". Although there are already professional investors (over 500000 CNY) who can invest in some Hong Kong stocks and ETFs through the Hong Kong Stock Connect, this is limited to ETFs listed on the main board of the Hong Kong Stock Exchange, with high liquidity and recognized as qualified by the Hong Kong Stock Exchange. If this restriction can be relaxed, it is possible to directly invest in Hong Kong's already compliant Bitcoin and Ethereum spot ETFs. Of course, this window has not yet opened, and it is unknown when it will be opened, but this path is relatively the least resistance. Of course, spot redemption is unlikely to be feasible, which is also part of foreign exchange controls, but making a paper ETF may not necessarily be impossible. In addition, it is compliant for Chinese Mainland residents to open bank and brokerage accounts in Hong Kong, but the trouble is that China's annual foreign exchange quota of $50000 is not allowed to be used for overseas securities investment, futures, insurance and other capital purposes. But in reality, this regulation is not strict, so if Chinese users really want to invest in cryptocurrency ETFs in Hong Kong, there is essentially no difficulty.
