You think there will be no more coins? 😒
Hopefully it won't go that way, but as legal tender... I think it is very possible. After all, we are writing on a platform powered by cryptocurrency 😂 Even governments are now looking at CDC's (centralized digital currencies), basically government issued blockchiain national currencies. China have already trialed this with the digital yen.
Essentially government issued digital currencies allow for much easier tracking and movement of money... it is no wonder the governments of the world are looking at them very seriously lol Once they've transitioned to these types of issue of value, there is no point in wasting resources on coins or paper money.
That's the crux of it, I think. In the U. S., there will be strong popular resistance to going all virtual. We can't even agree on getting rid of the useless penny. Let's hope we are ornery enough (at least in the U. S.) to keep physical cash in our pockets :))
