Economist Stephan Livera said in an interview recently that "the official ban is actually beneficial to Bitcoin. If the bank prohibits you from buying Bitcoin with a bank account, this is actually advertising Bitcoin." He explained this point by two reasons. The first reason is the risk and return rate of using cryptocurrency. If the currency is illegally used, this means that the risk of using it is very high; the second reason is that restrictions on the purchase of bitcoin will lead the public to the underground market. The market's demand for bitcoin and other cryptocurrencies will also increase.
