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.
This is something that I advocated for a long time. If you are doing something that is financial education like for your children then you will have kids that will grow up to understand how economy works. If you do not do any of that, then they will grow up to realize what money means after a very long time.
When people understand the value of money after 18+ years old, that is usually not a great way to make money or understand it enough to start making money. All those rich people that come from rich parents managed to make a lot of money because they got help from their parents but also they understood what money meant and were educated about it.
