Many countries in various parts of the world, especially Asia, are busy installing their respective rules regarding the use of Bitcoin and other virtual currencies. Different regulations in each country actually lead to polemics. Owners who are not allowed to use Bitcoin in their country, will look for other ways such as crossing to neighboring countries that have more friendly rules. It is considered inefficient.
I think for big countries have said that bitcoin or cryptocurrency can be profitable in financial terms. There is no problem so far, I think, the problem is only with the crypto market, where there are too many negative issues spreading about the crypto market so that there will be new problems in every fall of the market.
