The price of Bitcoin is never fixed and its price fluctuates so holding it has the potential of profit and that is why holding Bitcoin is profitable most of the time. And everyone has a plan to hold Bitcoin and earn profit from it. But that's not to say that Bitcoin can't be spent.  Money is an invaluable resource in every country and nothing is possible without money.  Money is the key to everything so why do people just keep money without spending it?
Bitcoin is digital currency and using Bitcoin is an easy and safe medium for this digital world. So I don't think spending bitcoins is bad idea. Of course, it is foolish to waste bitcoins on unnecessary activities. Bitcoin is not bad to use but it should be noted that it cannot be used for any evil or unnecessary purpose.
