Bitcoin is a long term project. Therefore it makes sense to save small parts over a long horizon. Do you save Bitcoins for your (grand) child or children?
For those who do not have (grand) children (yet), would you save Bitcoin for them if you would have (grand) children?
Just build up your wealth, and forget about your descendants.
And after you are rich, you can now thing about giving money to your family, but this should not be your goal. Help yourself first, and then comes the others.
