I'm saving my coins for the future but whether you should or not is up to how much you believe in bitcoin. Nothing is guranteed but I can certainly see the potential bitcoin has but that doesn't mean everyone else will. Maybe just buy a little and what you can afford every month but don't go crazy and invest more than you can afford to lose.
It is not a bad thing for you if you try to save Bitcoins for the future if you want to make some money. It is not guaranteed that you will make money in the future there is always a risk that comes with it.
Saving is very important as in the future we might face an emergency when we need money for the expenses. I don't find saving bitcoin as a form of savings, instead I will consider that as an investment as the price of bitcoins is not stable and who knows in the future bitcoins will be useless, we can never tell therefore only save or invest what you can afford to lose.
