I think cryptocurrencies will be successful in all countries where people are skeptical about the country's fiat currency's value. This goes for China and the yuan. From my time in China, I can tell you all the government cares about is stability. So long as the government is stable, people who are actually using cryptocurrency will continue to do what they're doing under the radar. The government doesn't want the fuss. The status will stay the same there as, maybe, in the US.
