If you add speed and spread to the public, then the future is cryptocurrency.
More likely, but for sure it takes time. And for me, even cryptocurrency will be widely spread to the public in the future, the traditional way will still not go away, it's still there. That's what I am thinking also in cryptocurrency, it's still like neutral, you can use it or not, you will gonna be decide on it.
Traditional money will always be there because crypto usage can't cover those individuals that are living in remote areas. Many people still prefer to live in isolation or far from civilization. There are also individuals who are living in cities or urban areas that are still unbanked and not connected with the technology, and they prefer that way. Though crypto will increase its adoption but the traditional way, which is fiat, will not disappear anytime soon.
Yep possible. But do you believe in the future that all people will be banked just using cryptocurrency? Like all areas will be having an internet connection and everyone will have the capabilities to use cryptocurrency since internet connection already has for everyone.
I do believe in this but maybe in the next centuries or more centuries? Well, who knows. It's still impossible for now the next few years.
