I don't just mean bitcoin has benefits, fiat and gold are useless, I mean bitcoin is a multifunctional asset. I'm not a fiat hater like many others because no matter how bad it is the fact that we are still using it every day, and without it we would have a lot of trouble in life. Gold is not profitable with bitcoin, but its safe. I invest in bitcoin, but I am saving gold for my kid's future. All 3 have their own benefits and different use cases.
Fiat currencies and gold are also multifunctional, but well I'd say that I don't like fiat and we still use it just because bitcoin is not widespread in the world enough. Otherwise I'd prefer to get payments and pay in bitcoins or sometimes probably in some other decentralized cryptocurrency but not in fiat. Just because it is not possible in many cases I still use fiat. But if some others would like to use fiat when we all will get an opportunity of not doing so I'll still stand for their right on choice: even if I don't like fiat they should have such option.
