Replacing of dollar won't anytime in the short or later. As the usage of cryptocurrency keeps increasing it might contribute in a large scale to the growth of the economy. Dollar is something beyond the cryptocurrency, it can be of the usage or it can be based of the trust it has gained from its historical value.
