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.
Unfortunately that even there is a wonderful development like this last year but still the bearish market is still in effect in which Bitcoin price might fall to as low as $3,000. This shows that even chinese people are now freely involved with the crypto market invesyments but still its looks like its not enough to trigger the bullish run. Hopefully the acceptance of ETF products will do.
