Economy will simply flourish. GDP will grow a lot. Countries that will regulate crypto to much will not see this GDP growth and cry latter.
Oh wow, care to elaborate this opinion?
How crypto will positively affect GDP growth?
Most people on the world have no access to banks. and this banks will be automated. Those that have they get paid weeks or months after deal is done. With Bitcoin you can use your coins the same hour. All digital asset will get tokenised to prevent piracy. Much more that I could not think of.
I think we should all think of this stuff when there are already company that is paying their workers with bitcoin because the idea is not really possible. It's like suggesting the government to be fully decentralized, and that would be a fool idea if you let your people out of your control. Moreover, it will be hard to sustain the financial capability of a nation when something like this happened.
And having that kind of society is risky as there are more prone to hacking, that idea just makes the hacking more interesting for many people.
