Since many uses bitcoin as the new cashless method. So does it will effect to each own country's economy?
It will and that's gonna be a huge change. Since bitcoin became popular the changes occurred in so many ways. Not only economic but also with the state & government exchange. Since the technology is helping a lot with the progress and success of bitcoin, it is rising in the most positive way people would want it to be and I think it's pretty nice.
It will surely affect the countries' economy. many governments have already understood that there is no need to ban Bitcoin. The best way for them is to tax BTC. Thus, they are going to improve their economy doing it.
