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?
by hacked, i only mean btc exchanges and by 51% Attack, i mean hash power is seen as by many the king in the btc world; and by security, Large Bitcoin Collider is working to smash open btc wallets.
