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.
