You are right it will be all profit for us and it will help us to make more income, actually the price of bitcoin is almost about the number of users and the number of investors, so if more people will buy bitcoin the more price of bitcoin will get high and it will be more income so it is all our benefit we actually need to help it make more famous and more popular so that more countries will accept it,.
