This depends on the direction which we are to look at. From the past, we will see that no government of America has been able to stand firm for the possible use of Bitcoin or crypto currency, and at his first time, the noise of Bitcoin was coming up, and now he fully made the public use and legalized it and which other countries are now dancing to.
