Some says crypto can soon replace fiat but how can that be possible ? I mean we must first need fiat in order to buy cryptos . you cant also say that we can mine crypto or we can earn them online because we still need money in order to buy a miner or to buy a gadget with internet access  .

Btc and cryptos were now also easier to use compare to before because many merchants and companies are now open up for supporting crypto payments but i think fiats are still more easier because they are direct .
