Its possible but it make take decades before it happen. Bitcoin may increase its value but it will have a hard time to get in the main market around the world. Maybe the whole cryptocurrency can be a good alternaternative for a fiat money but it will never be the main currency I think. Our government will always find ways to protect fiat money, but a least cryptocurrency will be accepted around the world in the future.
Yes that's right. Bitcoin is very good and a big help for our future. It will also lower the rate of poor people in this world. It can also rise our economy.
