They key is to not get angry/frustrated if they are not seeing the light. Just keep on adding bitcoin into random conversations here and there and slowly, but surely there will be more discussions about it. You will see. I try to pay my kids in Bitcoin whenever I have chance, but of course, they can't really spend it on stuff they want, so that is a bit challenging. For now, they are happy knowing, they got 100s and 1000s of something :). Rather than 1 cent.
