Agree. Not all nations have the technology to implement the cryptocurrency system in their economy. So I think that the currency of any nation will remain in its finances. If there will be the handling of cryptocurrencies in cities that have better technology infrastructure.
I have seen it in my country. When the banking system implemented mobile payment and not all citizens have access to a smartphone.
the current goal approaching that is to make people in the world use bitcoin or cryptocurrency as another way to make payments. Many limitations of cryptocurrency have to replace fiat, even more so in a crisis like this. although many people use cryptocurrency, most people only see it as a business area.
Fact!
Majority of people here on crypto doesnt really mind too much about its total adoption or its usage but rather they do always look at on the money making opportunity.
This is why everytime i do saw that someone do talks or have a topic about crypto replacing fiat then i do just simply ignore that one.Being optimistic isnt bad but we
should at least be realistic.
