yes i am also agree with you that it is good to save bitcoin instead of investing it anywhere else or using it for shopping etc, because the price of bitcoin is expected to increase more and more, and in near future its price will even cross 1500 USD level.
I can see investing Bitcoin to produce Bitcoin is much better than saving it, though saving Bitcoin is much better than spending it to some shops to buy something when fiat currency can do the job.
Saving money is never for fun purpose since if that is the reason, we can just see our saving be spend on something else, unlike being saved for future purpose, we tend to hold it for very long time so that when we sold it, it will elevate our status of living.
