Bitcoin can not end any currency, since bitcoin is as yet very little famous among us. Half of the world doesn't know what actually bitcoins is and those who know about bitcoin accuse it of a scam. Also, how would we purchase bitcoin if the cash gets end?. We won't be able to exchange. For me, dollars or any cash ought not to end. It might make a few issues and hurt the bitcoin itself as well.
Quite plausible, although bitcoin is still a topic that is being covered by countries and is being talked about a lot on social networks but in general, things are still not correct, even many media are exaggerating about bitcoin, and when bitcoin faces a large currency community like the dollar, with support from the United States, it is difficult for bitcoin to have a chance of winning. Ultimately, bitcoin is just the source of digital currency investments, real values are not stable and accurate, it cannot live independently without the currency of the world, keeping the same position as now is better
