Not saying it’s right, but it’s consistent with their outlook on politics and government.
Why should China subsidize world bitcoin production with more bad air for them? At least the other stuff they use electricity to produce, like cars, steel, and rubber dog poop, has a tangible value.
They've taken a huge shift to improve their environment. This is initiative is what caused them to stop accepting the world's recycling and causing the massive recycling bubble.
