If you think about it, China had almost no choice but to remove digital currency competitors to enable their own digital coin to become the norm.
Even if other countries will follow suit, they will do so at the expense of losing highly intelligent people who are an asset to their economy (just like China did as most crypto people had to move abroad), blockchain based businesses which are innovative with disruptive potential will also be at risk...
This type of decision is a heavy one to make because it heavily affects the economics of that country, and with crypto expanding more than ever the task will be challenging which is why the regulatory approach seems far more reasonable.
