Of all methods, cash is the only one that:
* guarantees no fees (assuming no currency change)
* guarantees no MitM interference blocking or slowing the transaction.
* guarantees privacy (you can’t even trust Visa, Mastercard, Amex to not sell your data; they have opt-out pages but that’s actually a trick to get more data from you)
