Bitcoin is not the biggest bubble in human history. The American dollar is. The last time it was backed up with gold is back in 1971. Now if they need it they just print it.
I and all people that buy Bitcoin give him the value. And this is how it should be and not some fake value like we have with paper money. Some people are whining about high volatility, well we can dump Bitcoin tomorrow and that would be the reality because we said so and not some government people.
