If you have been in China at some point of your life, you will understand how they do business in that country. So even if they say they do ban crypto or btc, for sure, a lot are still continuing their business.
that sounds like people are just gonna find some way to survive doing their business like mining bitcoin like this despite the regulation, i remember back then when there's a country banning bitcoin and the bitcoin traders there just move out their funds out of the countries.
the world is easy to access right now, people in doing business could definitely try to reside in a country with better law.
but regardless maybe its as he said, china never ban it in the first place but maybe put in a really strict restrictions that of course will cause the margin of profit to be low enough.
after all mining difficult right now is also peaking, recently hit ath of difficulties. which means lesser profit assumming the miners counts stay the same. cmiiw.
Regulations are not the same as in other nations, sure in the USA you could do something that is against the regulations and only be in trouble if you get caught and the worst thing for you could be some fine, you could pay a lot of money as fine, or just bankrupt your company financially and get out of trouble.
In China, that is literally punishable by jail, you can't just say "I don't care what the government says, I will do what I want" in China, that's just not the type of country they are. They are ruled with iron fist and NOBODY in that nation could go against the ruling party, last time a group of people wanted to protest, they literally sent tanks to kill them all, regular citizen protestors were crushed by soldiers. So, it's good that it's back now.
