Sure, the money is there, on the receiver's property. But the receiver might not even notice it's there unless you tell them. Similarly, with such converted addresses, the receiver likely won't even recognize it as a payment to them. | |

The sender unilaterally making unsupported assumptions how they may change the instructions to pay the receiver will certainly lead to conflict, if not outright lost funds.--Imagine you're running a restaurant in the US and when you bring the bill, the customer pays in Euros instead. Would you accept that? | |
