> These posts are entirely the result of authors who didn't buy bitcoins when they were cheap. They want it to fail, and try to find any flaws in it that they can, because if it succeeds then they'll really feel like shit because they missed out.

I see it every day. One of my coworkers used to be into Bitcoin and owned a fair number and then decided to donate them away when they were still a few dollars a pop. These days he can't stop making predictions about how Bitcoin is going to fail and how it's all a bubble and ponzi.

It's unbelievable how some people are unable to deal with their cognitive biases.
