If Chinese Mainland really wants to open BTC, it will do so: one ⃣ It's impossible for you to buy real BTC, you must first issue a national chain. Watch and control, trackable, and require real name authentication. Then issue something similar to CN-BTC to match real BTC 1:1 two ⃣ Corresponding to real BTC being centrally held by the central bank or a bank in Hong Kong three ⃣ The self issued 'national chain' is centralized and complex enough, so complex that you cannot trace how many CN-BTC it has issued or know how many real BTC are being held in custody While the Americans are vigorously promoting cryptocurrency, I don't think the mainland can be completely inactive. But it is also impossible to give up foreign exchange controls because of Bitcoin, and it is likely to be implemented through the method I mentioned.
