In the future, bitcoin will become the world currency. It takes time and of course it will be one of the currencies in the world. There are already many payments that can be made by bitcoin. In the future all countries will accept bitcoin, we hope that. But I think although this - the future will be better than the pictures I saw at the beginning of the topic. Some countries have accepted bitcoin for banking transactions. Bitcoin will not be a national currency. We need to look everywhere for the positive side. If the world ends. Bitcoin will live. Only faith can guarantee bitcoin. Imagine if everyone uses bitcoin as a single currency, it will affect the speed of the transaction will be more crowded and people will hardly receive their bitcoin.
