China may have the 2nd largest nominal GDP and PPP GDP, behind the US, but they are still like what, 90th when it comes to GDP per capita.
I agree and it always made me laugh when people act so threatened at the scenario of China emerging as the dominant world economy. It's long overdue for them and who cares? They have 1B+ humans and so much potential.
Regarding btc, China is still a significant economic impact but the symbolic impact is just as important.
But to answer the OP more directly: No, I really don't give a crap. People really need to look at the big picture and ALL current events. Consider things like Coinbase, Overstock, the number of online retailers accepting varying cryptocurrencies.
If China banned computers would you stop using them? If China banned comic books would I stop reading them? If China banned free speech... oh wait, nevermind. China was supposed to be departing from their 'we are an island' mentality but obviously some habits die hard.
