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?
Unless you are very old it does not make sense to save bitcoin for anyone other than yourself, besides you will need to teach them to keep their bitcoin because if you don't they are going to sell it immediately for the cash.
