crypto or bitcoin is functional, in addition to payment it can also be used as a trade with a large profit.
while traditional money can even be traded but the profit is not as big as crypto. so I think it's clear crypto is better than traditional money
Do you only view it from profit amount on trading aspect? You cannot view it on this aspect only, also learn how the difference between crypto (bitcoin) and traditional money on payment tool aspect. In this matter, I think traditional money or fiat is still better because it is accepted in all countries in the world. It is also easier to use since it is physical, not in digital form. Not all places in the world can use digital currency.
Its sad but this is the truth and not all would really be that open nor able to make use incase if there would be some full integration from paper fiat to digital if that's the case because
not all would really be reached on the scope on adoption and also people had already get used to fiat.
Its not bad to be that optimistic about bitcoin or crypto but minding about becoming a mainstream and tending to replace fiat is something that is impossible to happen..
Bitcoin could progress but it would really be just as good as an alternative and wont make it as a mainstream.
