Bitcoin is digital, not virtual. The rules of Bitcoins difficulty adjustment do not simulate physical laws, they are brought into existence because of physical laws. @Gigi
Did you know that billions of people worldwide don't use a bank account? Here are some countries with a high percentage of unbanked adults: - Pakistan: 79% - Egypt: 73% - Nigeria: 55% - Indonesia: 48% - Bangladesh: 47% - El Salvador: 36% These are just a few examples; many more countries have high rates of unbanked individuals. #Bitcoin could offer an alternative for the "underbanked" and "unbanked" worldwide.
