I store my bitcoins to in the future if the price will rise to earn a little money, but for me it's just entertainment because I have too small amount of coins and even if they will grow in price rich I won't. Probably the majority of people does not have more than a few bitcoins.
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.
If you are a worker and depend on bitcoin for the main income. Of course you will not use the advantage on bitcoin just for fun. Of course you will use it for something useful might invest it for the future
