I'm curious how the OP stored the Bitcoin they bought for the baby, they created a paper wallet? Bought a hardware wallet or any software Bitcoin wallet? It would be more amazing for OP to share how they manage to store the Bitcoin so just in case in the future, other will follow it too.
Just like me, I am planning to do it in the future for my children. Since I saw a lot of people having life insurance to their children while at very young age, so for me, I will do like what OP did.
It seems to me that it is better to create and control investments personally, and then leave this capital to your child as an inheritance. But before that, it is important to teach him how to make savings himself in order to create at least a small capital for investments, and teach him how to safely store investments. That he could repeat all the steps himself, albeit on a smaller scale. After that, I will know that he will be able to do everything right when he receives an inheritance and will multiply it.
