It could be a good idea to set aside a small amount for grandchildren. They may benefit from the gain in value more then we will or even our children will. I'm setting some aside anyway whether it's for me later or to pass on.
That is a good idea and I think that I am also going to do that and teach them a bit about Bitcoin if they are interested.
If they are not interested then I will not because I do not want to force them on using it.
you could still do it. primarily people want their children to have a go life and some money. so if you leave them some bitcoins and if they are worth something they will figure it out when the time comes. worst thing would probably be that they immediately convert it to fiat. in that case i guess you could leave them also some money, but the idea behind this whole thing is that the value of bitcoin is expected to go way up.
