These aren't values, but definitions and I'll have to disagree. It's an internet currency. Sure, you may use it as an investment or a store of value or even just to speculate, but the only reason it exists is to be used as a currency. If none saw it like that, it wouldn't have a purpose to be an asset.
People invest in things for their future usage. In this case, they invest so that one will use it as a currency in the future.
But I was also thinking if Bitcoin is used as a currency it can be measured in SATs where by we have 0.0000001 as the lowest and 100 million Satoshi in every Bitcoin. I still believe Bitcoin will get global adoption satoshi's white paper is too real and I smell adoption soon
