I don't think so. It just a daydream.
How you can expect that Bitcoin is going to replace dollar, are you crazy.?? You can't imagine the platform of dollars and its credibility.
So there is no way to replace dollar by Bitcoin.
Yes it is true in others dream maybe dollars will replace bitcoin even bitcoin will be turn into millions or billion it will no longer replace dollars for sure. The platform of dollars is the most powerful money on earth where this is the central currency of all currencies how come that bitcoin will replace it.
