I have been thinking about this a bit since getting involved with crypto and trying to explain to other people where does it come from...
But in the end the simple explenation is just that something has a value because the majority says thats what something is worth...
Fiat currency is worse, thats just value attributed to a currency backed by a huge amount of debt
At least cryptocurrency is honest and so will al these new coins be... Honest...
its more then what we have now
