I still think bitcoin is an asset, and it's hard to call it currency.
Because currency is going to be widely used, and bitcoin is hard to use on a large scale right now, I expect the lightning network to change everything.
This is quite interesting. Bitcoin was created to be a digital currency. Bitcoin becoming an asset depends on the individual and how you value and take it to be. Asset is something that brings profit and bitcoin does so if and only if the price rises to an appreciable amount.
