I don't know where you live but that's certainly not true in my country. Even getting $10 for a birthday gift is already a lot, especially if we're talking about children. Your hope makes sense if people use Bitcoin regularly already, so I don't think it will drive adoption that much. I agree that a business can take this angle to offer a competitive proposition. I don't think marketing to encourage people to give birthday gifts will be enough to drive up the volume. It's not like a person always has a close friend who lives abroad. CMIIW.
