There is a fee for crypto transaction processing. The fee is the same irrespective of dollar value, so for small transactions, like buying a game, it is more than a cc middleman fee.

Eventually, I think k this is where crypto can work. Something like the digital euro where the transactions are processed by a trusted entity, the European central bank, rather than your local bank through the visa or MasterCard system. If those fees can be low or eliminated, visa and MasterCard are dead.
