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.
In my opinion the future of economy will depend upon cryptocurrency in the future. In the future the whole world will use only bitcoin for their general use and all other currencies will disappear from the market. When we have one usable currency all over the world, buying, purchasing and trading will be easy and the money circulation will never stop. It is the growth of economy.
