Not sure where fairness even needs to come into the equation .. ?
Anyways, the realization of instantaneous and cheap money transfer would be something many people are interested in. Have you seen the wire transfer fees that are charged to purchase and import goods into the USA for entrepreneur shops?
Specific example for you here, bringing a $4000 shipment of electronic cigarette related goods can be done with ease if parties involved were to transact using a cryptocurrency. Less work is needed to be done to perform the transaction. This is an example outside of fairness.
That $4000 purchase usually has ~$100 in fees just for processing the tx, with a CC it's pennies (excluding bank fees ofc, but the necessity to change back into fiat is outside the scope of this point). The reason for the difference is because less of an infrastructure is required to process the transaction, not because it's 'more fair' to pay less or whatever tangent that comes from. Where's the flaw here?
