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.
For me it can both it is a electronic currency. It can also be an asset if by trading with bitcoin you have earn a profit and you just hold it for future use or investment. Will for me it all depends on how the person actually uses it.
