If asked, can the government ban Bitcoin? The answer is yes. In China now Bitcoin trade has been banned for people, in Japan and South Korea who previously agreed to inaugurate Bitcoin as a means of transactions now precisely prohibit Bitcoin. Many countries ban Bitcoin trade and transactions for various reasons, one of them by looking at the shortcomings of Bitcoin itself. A simple example of the government's fear of Bitcoin is that many criminals want to hide their crime money through Bitcoin. Because if they save money in the bank, money from crime can not be traced easily.
