There are many countries who are worried about the price volatility of Bitcoin and try to regulate it with harsh tax methods or KYC standards for exchanges but I dont think they will ban bitcoin, simply because they cant ban it completely.
Bitcoin was staging a tulip bubble of the year. 70% of bitcoin is excavated by Chinese every year. Although Bitcoin is a medium of exchange, it is not so much a currency as it is a commodity. The regulatory authorities in mainland China have all along stressed that the economy should take full advantage of the reality and protect the real economy.
