Another alternative to banning is to move their mining rigs to more crypto friendly country...
Moving to a new country isn't as easy as it sounds. These people have a life in China, family, children, friends. All that can't be abandoned over night just like that. Not to mention familiarizing yourself with the regulations of the new country, finding an appropriate and cheap location to set up your farm, and physically moving your equipment from point A to point B. All that takes time and money. There is also the language barrier, cultural differences to consider, etc. Of course it's doable when someone forces you into it, but I believe that's not what the Chinese miners want to do.
This is an interesting take. I usually think of the mining outfits as large companies or companies that have made enough to be able to move when forced (like this), but surely there are lots of operations that may just have to shut down because they can't overcome the barriers you listed. Moving across country lines isn't as easy as pick up and physically moving, there are import/export laws and regulations and stipulations that could all make it very difficult, even if you DID speak the language(s) of the new locations.
Thanks for sharing this perspective.
