The concept of gifting to your offspring has become very corrupted by fiat money psychology. The magic idea of a gift is to think about the person and what you can do for them which will improve their lives and so financial gifts don't require much thought and the value of this gift is less relevant.
Supporting your children is important and so setting aside as much bitcoin as you can for them is good. Giving it to them in a way that does not compromise hardworking ethics and frugal/capital efficiency or make them subservient is the challenge. I think it's more about how you do it, loans, prerequisite learning etc, than about how much. It would be a good thread to work this out
