A lot of the Chinese crypto engineers (of which there are many) are paid in USDT. This avoids all of the capital controls and knowledge the state has. There is an entire subculture of Chinese who operate their businesses in USDT, mostly digital ones but it has bled into the physical world as well. In Hong Kong duffel bags full of paper currency would be swapped for USDT by various money changers.

A lot of people look at crypto and see what’s on the surface. The easy, instant movement of essentially unlimited money without government oversight and intervention is scaring many authoritarian governments. See the total ban on crypto by the Chinese dictatorship.
