No doubts. It could be a good idea to set aside a small amount for grandchildren.
I hope that the development of humanity will step into the future for as many fast that the grandchildren or great-grandchildren will not need anything. While agree that bitcoin savings in the future will give a very huge profits for our descendants.
Well its debatable if bitcoin will rise or fall in near or far future. But it wont hurt to save some for future. But how much is better question. Because if you save small sum for grand children maybe it will be too small amount, I dont think that bitcoin will rise that much so that you can for few bitcoin become rich in future.
Thus still profitable to keep bitcoin until a certain time, namely for the high prices, but already there to be seen, who would get the coin. The main thing that prospects were good.
I believe that Bitcoin will be much more expensive in the future. and it's a good idea to take care of their grandchildren and keep them some Bitcoins.
but so far I have no way to do it. I do not have grandchildren yet
