There will always be someone on the other side of the fence compared to where you stand. So long as bitcoin exists, people will hate it. Why? People hate change, people despite what they cannot understand, there is many reasons.
Thats right, people will always hate you if you will try to change something around them or if you want to bring something new between that they dont know anything about, so that is exactly the case with bitcoin, the ones who does not know it and its usage would possibly hate it or hate the ones who are using it.
