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?
It is definitely not ideal.
For one, the confirmation times are obviously a lot larger than it was like 3 years ago. There are scalability issues and there is obviously a lot of debate going on currently regarding how that issue should be handled.
However, ideal money is completely imaginary. There will never be a currency that is perfect in every aspect, as some aspects of money are actually contradictory to each other and cannot be achieved at the same time.
