I believe that crypto-currency has a great future, but, to be honest, it is too early to say that they can replace Fiat. Perhaps in the future we will more often use digital currencies as a method of payment.
That depends on the user's preference. Average users of this forum are those who are cryptocurrency enthusiasts and are willing to use their crypto. But think about the whales who hold crypto for the long term. For them using their coins would seem like a joke, because thats not what they got in for. They are eyeing the long term pump and dump of bitcoin. So the opinion of use is divided among those who want to hodl and those who are willing to spend.Parting with crypto is a tough choice for many. For that I guess fiat is what people prefer.
