How can cryptocurrencies be used in daily life?
I can say that it is an appropriate analogy here to say that the same problem has been experienced in trade between civilizations that discovered money in the past and civilizations that still use barter. While the Lydians offer money in exchange for goods, we cannot say that they are wrong if the other civilization says give me so many cows, what can I do with the money?
However, today we cannot ignore the clarity that crypto money has value. While there is a clear equivalent for a payment I will make in Bitcoin, even by states, this is an agreement that has an equivalent in all currencies after the person who accepts the payment knows how to convert it into cash, use it as an investment or use it.
As long as adaptability and accessibility are improved over time, being a fast payment tool like a physical crypto ATM or POS device can be functional.
