everyone who has charged fiat to an exchange, bought crypto, deposited to a private wallet, send back to an exchange, sold and then cashed out back into fiat knows exactly that there is no cryptocurrency that is either cheap nor fast.
all that transaction times, network fees, exchange fees and charges... and then? one typo, one transposed digit or any other mistake and you are entirely fucked up.
haha, now imagine the entire electronic money transfer of the world done by the eth or btc blockchain. i mean come on, get real.
we would probably have to cover an area of a medium sized country stuffed with power generators and supercomputers just to power and process this hell machinery.
no proof of stake, lightning network or other shitty workarounds that do not solve the initial problem will ever change that.
im totally into cryptos and i surely believe one crypto (that does not yet exist) could eventually replace fiat. but we are far from that, very far.
but to be realistic, there is no practical reason for a resource hungry blockchain.
on the other hand, i dont see a problem when people say a crypto does not offer any real world value. i mean, the times where countries banked an equavalent of their currency on gold or where coins are worth their price with the metal they are made of are LONG over.
Money is a commodity with the sole purpose to exchange other commodities or services, it does not need to have a "physical" value itself.
in future, we (uncle sam) want our money to be:
-Heavily encrypted (quantum computer proof)
-Safe (counterfeiting)
-Traceable (to track any kind of crime,terrorism and more)
-Easy to use
-Easy to maintain
sure, maybe in future there will be a crypto (probably without blockchain, more something like IOTA) that could do all this. but maybe not. we will see. sure is none of the existing coins will replace fiat, ever. not even close.
