You have some reliable source, I was looking in google and I get old articles with many speculations, if really China releases the cryptos in the country, that would mean that the bull run of December can still happen, I want to believe that but several years in this medium have made me a little skeptical.
China has biggest population and many people are good in technology. Their are speculations that they are going to released the crypto, yet not totally get into the point. The country usage in buying things is crypto because they practiced for their own good and betterment of the project.
