If will dont store then its worthless because from elementary economics we learnt that for anything to be money then it must "store of value" I.e we should be able to store it and even in the common sense way how will it be interesting if there is no forces of demand and supply playing out on Bitcoin if some people didn't hold and create artificial scarcity then increase its value and do otherwise then decrease it value and that is the beauty of Bitcoin.
It is better to save most of the bitcoins and use a small proportioin of coin. So the circulation will raise the price.
Good thing some newbies think like this and we need more of that to encourage merchants into making business in the bitcoin territory. That will really help a lot when they read this kind of thiughts from new ones.
