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 have two children and they are still a baby, before me and my husband did'nt know about bitcoin we are lack of financial,we didnt know where to get money to pay our expenses and our salary is not enough to sustained our other expenses.then we found bitcoin and now we have also a savings for the future of our kids ,for their future education or other expenses.we did not know what happens next so now if we have extra incomes lets save for the future of our kids.when my kids grow up i will teach them also about bitcoin to get money and saved.
