Well, let's not forget that a significant percentage of the "decentralized" bitcoin mining network, operates out of China[0].
Currently BTC.COM[1] and AntPool[2] combined make up 42.5% of the network and both are both owned by Bitmain, a company headquartered in Beijing.
ViaBTC[3] is also a Chinese mining company operating out of Shenzhen and has 10.1%. I'm not going to bother checking the rest since that's already 52.6% of the network controlled by 2 companies under 1 authoritarian regime.
