It would depend on how Akira planned on donating the proceeds! If he wanted to donate them to orphanages/soup kitchens/etc then there is a chance they wouldn't even know. If he wanted to stop a kid in the street and hand over some of the coin in person, he will probably be met with a lot of strange, suspicious looks. But over the course of his time in El Minha, if he keeps consistent with his donations, they will start opening up to him more and seeing him as more of an ally than anything! More comfortable around him, more trusting, etc.
