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?
Its a good idea but you dont now if bitcoin is still have a value at that time, or how much is it no one knows its money you need to decide what is good for you , and for me I will use it now .
