I am very sure that time will happen, the old concept will change with a new concept. the concept offered by cryptocurrencies with its Blockchain technology will greatly help the lives of humans in making transactions and others.
indeed evolution will always play a role in life, with time, of course new things will emerge and be used by humans, leaving behind old habits. but for that I think it takes a long time, because there are many problems that must be faced
that's right, but we also have to see that the current development has no potential to replace fiat. in fact cryptocurrency must be very stable before crypto replaces fiat, moreover there are so many things to think about.
