One of the best gifts that a parent can currently give to their children is leaving an investment for them or teaching them about investment. There have been many topics about how teaching children about investment opportunities especially with bitcoins. From all those discussions, many of the opinions and perspectives are about not forcing your children to learn about bitcoin investment when they are too young.
Leaving bitcoin investments for your kids isn't really a good move. There are other investments "By the books " with very nice ROI. The problem is the risk involved in transferring hodlings. The internet can be a very dangerous place for those that are not properly informed. The only exception where leaving hodlings for your kids plays out safely is if they have proper understanding and interest in both privacy and Decentralisation. Else you may end up hodling for a random scammer or hacker to steal in the end..
For me I instead of leaving a Bank share investment for your kids in this contemporary time, I will rather choose to buy some amount of Bitcoin for them, hold it while they grow up, at least when kid grow to some certain level it not bad to start teaching them finances and money management, since such education is not restricted to 18+ as other things, so I can begin Bitcoin education for my kids even in pre secondary level.
