I used to "hate" bitcoin out of ignorance. Like many others, I thought it was a scam, a ponzi, a tulips-like scheme.
Even when I knew a bit more about it, I still hated it cause it felt unfair that some people were getting filthy rich out it just because they were in it first. It did not feel right that a system that many claimed to be a possible "currency of the world" was distributed only to those who knew about it.
