Say that we trust each other, I am visiting you, and I wire you a sum X in the currency of my home country, and you give me a sum Y in the currency of your home country, without any intermediaries.
Are there laws and regulations about the amount of money which can be transferred between countries this way, and where can I read about them?
I assume that services such as https://transferencias.global66.com or the banks take commissions on such transfer, which are justified as they take in charge the risk and trust factors, and that such commissions could be skipped when the two persons involved in the exchange trust each other, but I wonder if there are legal restrictions on such exchanges (and on the amounts being transferred).
