This will be tough for China to enforce, as Bitcoin has a lot of money tied into it and I have read that a lot of Chinese are investors or miners of coins. I also am still not very informed on how the Digital Yuan will work, so I wont comment on that just yet. This seems like a blanket ban and its hard to say if this is just for Chinese markets, or if you already own coins what the consequences would be. I expect others to follow suit, but its also worth noting that some countries are going the opposite direction with digital coin like El Salvador.
If you've been following what Democrats now want to do and that's be informed of bank transactions in excess of $600, you'll see Bitcoin surge.
Um, no, this is actually something that can be done with a mouse-click. China can block websites as easily as you can. If you can't access the necessary websites, then you can't trade, right? Hell, you can't even see what your titcoins are worth. You can block phone numbers, too, to prevent telephone trades. Technology is wunderbar.
Crypto is nothing more than a fad. It has no more value than the paper we currently print our worthless currency on...
