They are too shady on this. Yes although that they are banning their citizens, companies, financial institutions, banks, etc., from adopting cryptocurrencies because of their mindset that it’s a threat to the digital yuan, yet the government is still holding a lot of BTC. I think secretly they are purchasing more BTC and selling it for profit or so.
But I do believe in the change of heart though. If you look at India and Russia, back then they are set to ban crypto mining and trading and criminalize those who get caught holding or trading it. But right now? They’re regulating it instead which is a good move apart from a high tax rate.
