Why not it seems like a good choice to save for our future even if its not bitcoin Fiat could also be a good way.
Even if we still don't have a kid right now let's try to save for future expenses .
I agree with you. bitcoin is not the only way to invest in the future. I think other tools can also. but it is currently very good bitcoin made as an investment tool. I have no children yet, and if I have a child I will teach him how to invest with bitcoin.
Even now there are a lot of assets that you can put your money, bitcoin is not the only digital currency, there are a lot more other too. Bitcoin has the highest price but it is not the only digital currency that can be traded. There are many alternative coins and also there are new upcoming new currencies.
