The best way to gift Bitcoin to coming generations is by introducing them to bitcoin and help them in getting started with bitcoin since thats the most difficult thing new comers faces for bitcoin. I have already handed over my bitcoin keys to my son who is 12 right now in case anything happens to me and he is loving this new technology
If other country are introducing the blockchain at early age by studying it in school will be a good idea, so let's have those future generation to become aware what it is at a young age because there's a lot of kids right now that will create future and we might have a young satoshi with them, so let's teach while they are young .
