Three years ago or two years ago, if you asked me what Bitcoin is, Id tell you it is the future of money. It is managed by the network, not by the government. Plus, it is private, anonymous and fast. Its just perfect!
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. Id say bitcoin means more about possibilities, possibilities of expression of value. Before, Ive been taken it for granted that the government should control currencies. But now Id like to take a moment to think of the question:
What is the nature and origin of money?
Bitcoin was never meant to be perfect, it was meant to be good enough that the normal person could use it, contribute to it, and secure some of their wealth outside of their economic system of origin so that they wouldn't be subject to the complete control of banks and at the mercy of governments who wouldn't bail them out.
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.
