Yes I am saving bitcoin for future purpose and not for fun, because I am not thinking to gamble my bitcoins, if ever I have a bigger holding value. Saving without good purpose ends up to unworthy activity because most of us who has money will be planning what is best for our future specially when we had a family to support for, like a married person having kids.
Even if you are saving for a purpose that is not very serious the truth is that even then saving is very useful since in the case of an emergency you will have some money in hand you can use for the emergency even if that was not the intention behind that money.
