People need to understand that replacement of Fiat will mean a death sentence for the people who are still working things out with the virtual cash inflow.
The thing is , there are too many people living in poverty who cannot even afford the cryptocurrencies , how are we going to leave a sector alone and allow other sector to flourish?
This won't work until and unless people are at least middle class and the cryptocurrencies are not volatile.
Exactly, not every single one of us have capability of getting ourselves our own crypto for not all of us can afford it. And honestly in my opinion you cannot replace fiat, well for now. It will surely afffect the general flow of money and people will be divided and that may cause slowness in transactions. If we're gonna go for innovation then let every one go for it.
