The chinese government or central bank is not CHINA.The people of China love bitcoin and cryptocurrencies.
Why it`s so important for the authorities in China to track all transactions?Taxation,money laundering or something else?Total control over the financial system is almost impossible.
They not only want to take control over financial system , they want to take control over everything. This is why they already banned whatsapp,facebook, twitter, gmail,youtube, pinterest , pornhub and so on. (there is less space to complete the list). So bitcoin is no surprise at all.
