At the present time, btc has not been recognized by people around the world so it can not be converted into a legal currency and its features are unlikely to become an official currency. I think bitcoin is often regarded as a kind of asset and it allows the user to trade quickly with the anonymity that many people like.
Crypto-currencies still did not come out of the shadows. Most of the population of the planet has not yet studied this phenomenon. Crypto community is very small. It's too early to talk about accepting the bitcoin world.
