People only hate it because they dont have enough data about it or have bad experience with bitcoins and they just are desperate to understand real benefits of bitcoins.
I don't think people hate bitcoins, because at these present days most people of the world still does not know about bitcoin, and people can't hate what they do not know. However I think there are many persons that know about bitcoin and still are distrustful about it.
That is what's holding back investors. They are very aware and knowledgeable about bitcoins but the reason they are not investing is that there is some quite of price fluctuations issue because bitcoin can be very unpredictable at most of the time with it's price, but being a long term investor, I need not to worry about fluctuations.
Yeah, some reason that made bitcoin not so famous because its volatile to get hacked and the value fluctuate. So many people or company not trust to invest on bitcoin because its not stable yet. Just like when bitflixnet get hacked and the price of bitcoin fall, the matter of secure. People need guarantee of security or at least the currency already stable.
