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.
As said, many are not still aware of BTC and its benefits. There is no reason for hating btc. When you get good returns from something, what is the need of hating it. Must be very happy at the returns we get.
You will be very happy of course if you bought Bitcoin at around 200 usd. but if you bought it at its peak (1200 usd) and still holding it, am sure you are still worried on how you will recover you investment

. What ever happen, there is no reason for you to hate Bitcoin, it's just a tool/medium/currency that can be use to get your goal in life, any negative isn't bitcoin's doing but those people who failed to choose the right decision.
