A lot of people seem to think it's that easy, you just replace fiat with Bitcoin, everyone is happy and everything just works. Imagine if the world was run by people who only think 2 moves ahead  Fiat is part and parcel of the modern world same as your blood and veins are part and parcel of your body. You can't just replace your veins with a few plastic tubes and live happily ever after  At least not yet.
