And Bitcoin is proved very successful. But it has inherent risks like anonymity, hacking,51%attack, double spending. Stop imagining bitcoin is perfect. No coins are perfect. I’d say bitcoin means more about possibilities, possibilities of expression of value. Before, I’ve been taken it for granted that the government should control currencies. But now I’d like to take a moment to think of the question:
“What is the nature and origin of money?”
Money is never perfect, most of the time we just have to do our best and make sure that we don't mess up. We may have a "perfect" system in the future, but that is never for sure. Chances are we won't see any sort of perfect system for a long time.
