I assume that they will release their own cryptocurrency by adopting blockchain technology. China is famous for monopolizing the market but their support in blockchain itself have a good impact in the current prices of bitcoin and many altcoins. If they have their own coin in the market, I assume that they will implement it nationwide to maximize the use of blockchain technology or will try their best to gather more investors outside the country. If it is the latter, then they will soon have the power to manipulate the crypto market to their advantage if they are big enough to do so. It will be important to expect it and plan your investment and trade strategy well.
