Nobody is taking China as an example (apart maybe from NK), not in economics, freedom of speech, law or....anything.
So there will be no after effect.
It isn't really the Economics of China, rather the example of Bitcoins volatility due to the ban that may be used as the example.
This itself may play a roll in future decisions perhaps. I'm not sure exactly how, I guess this is why this discussion was started.
Would other countries even care about any of this?
