Why would they be? The PBoC isn't anti-Bitcoin. It's all about capital controls and money leaving the country. Mining is productivity.

I wouldn't be surprised if the PBoC themselves got into the BTC/CNY exchange business. They could limit BTC withdrawals within the current foreign exchange limits, steal the big three's business, and make tons of money.

Why outlaw something profitable and create a black market when you can legalize it, monopolize it, and tax it? Kinda like Justin Trudeau's cannabis biz or what's happened in some US states.
