That's quite right. They always bring their own version of every tech and ban the westerner version. That's how China deals with the west but it is not like it won't have any impact on bitcoin. It will have its consequences. Millions of (some may even say billions) Chinese people will be forced to use the C-BTC and that's probably create a pressure on the btc prices. In the long term it will be fine... unless the west bans it too.
Maybe you all know that this is already familiar in China. Look at the products around your room, or Chinese imitation products. wouldn't that destroy the original label? So I actually think that what China did at the time of blocking Bitcoin they would most likely copy. After studying several years from mining to finally closing it back down, it would be quite unexpected. They can actually use the time during mining to learn and build their version of Bitcoin. laugh out loud
Didn't cross until now, we ourselves might have noticed. But this is China madness, to dominate any sector of the economy they will chase until they succeed in duplicating. Damn why should we trust China.
We have to learn from the case of the famous product that China duplicated until now.
