Depending on how old your daughter is you can give her concepts to understand what cryptocurrencies are but if you want a crypto investment for your daughter, you should also remember that there are risks doing that, it is not a 100% solution although it could give you profit.

It is awesome that you are thinking for your daughter's future but for now, it is better to have a stable income for you and your family to have some savings, death is one reason to be worried but there are times that it is not actually worst than that but it is expensive like diseases. Better earn and save what you can right now and as they usually say, invest what you can afford to lose.

Your daughter's future won't depend on how much investment you have for her, it will depend on how well you will raise her, remember that.
