Considering the fact that the bitcoin mining in China wasn't that big and wasn't using that much electricity and the amount they were using were coming from clean renewable sources that wouldn't have existed otherwise and also comparing it to the entire population of the country with 1.4 billion, this reason doesn't seem to be the right motivation behind the crackdown.
In fact I believe it was a move to push people into using their centralized govcoin that they plan on creating (digital Yuan or something like that).
If to look for one of the most centralized government in the world that loves nothing about anything that is not from their country, then it is China, China has the technology and power to make bitcoin mining possible, everything can run smoothly, and not that miners will not pay for the electricity but just that China can never be happy about what is not from their country that they can not control unlike Yuan and their digital Yuan.
As per the article from coin telegraph, it states that Kazakhstan proposed the increase in electricity rates Kazakhstan specifically for the miners, so it means that the electricity used for households or in the industrial sector (not for mining) will still be available at low rates?
If this is so, then how anyone can distinguish that the electricity used is for the mining purpose or some other usage?
It is about miners in Kazakhstan, other business organizations and households are not affected by this for now.
