Seems many people treat bitcoin like an asset given how much it's gone up over the last year or so. But some academics disagree with that assessment. If it is to be treated as a currency, it will need to stabilize to be of use.

as far as I know bitcoin can be called an asset because bitcoin so far is considered able to accommodate people's treasures in the form of investment, but I can not say that bitcoin is the currency because it does not have an absolute unit of measurement
