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..
I think its rather a good idea to leave Bitcoin investment to children, though it is requires that this children should have attained certain ages, at leat, they should have reached adult ages levels to make some decisions. In facts, at eighteen years of age, children should be able to learn about Bitcoin and the investment options. Teaching children below the adult ages(that is, below 18years) is equally not a bad idea provided that this children are interested and are will to learn from their parents.
You can't be concerned except you are convinced, vice versa.
