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.
Because of many things in its nature, bitcoin is still not ready to be used worldwide as a currency or a payment method, so all the guys, who are thinking, that bitcoin soon will overcome the economic system, just does`nt understand what it is actually.
