Hillary Clinton should go to the old age home (74 years) and run the Chess committee there, because her time has past as a good politician.
China only banned mining because Beijing has decided to stop importing thermal coal and to reduce their carbon footprint. This caused energy shortages all over China which also caused Beijing to ban energy usage that are not essential to the economy of the country. They had to do this to protect their manufacturing sector. I reckon if there were no energy shortages, cryptomining would remain allowed.
Another cause of the ban might be because Beijing does not want the cryptospace in any type of presence in China. This is because OTC desks were using the cryptospace to become the facilitators of laundering money from illegal activies and scams.
