If everyone around the world gets into cryptocurrency, do you think it will even help in solving or lessen socioeconomic problems? Can it be used to buy goods from other countries? It is fair to say that crypto will help a lot of people but what will it do to one's country? Will it help improve a country's economy?
I don't think it just helps a country to grow well, it will help the whole world grow better thanks to its technology. But to gain trust from countries around the world is not easy. I think it will grow slowly until the world realizes that a smart technology can solve many transactions at a rapid rate.
At that time, you will see a lot of new businesses growing up to be able to serve everyone in the world.
