Isn't the people of China not allowed to have a cryptocurrency because it is banned and only the government can have bitcoin? I am pretty sure that it won't affect it that much but we maybe it will affect it a little but who knows.
OP don't even mention where he heard such information, so i have some doubt. However, even if true, it's likely they (people of china) can't have control over their coin.
When bitcoin holders in China become an issue where they cannot access bitcoin, then only the Chinese authorities freely control it all. maybe for some Chinese citizens it will be difficult without access to the market and owning bitcoin.
So in my opinion, China is making a decision that really hurts bitcoiner in other countries, because in fact the Chinese government plays a very neat role, namely owning a large number of bitcoins and spreading through millions of wallet. but in essence there is only one complete control.
china makes this drama seem like a public problem, even though they have been manipulating this issue for a long time.
