I can not see some one hating bitcoin unless they do not know how to use it.
That is the only reason I can see for anyone hating it.
Actually if they came to know how bitcoin works than they will be actually intrested in bitcoin. And with all the buzz right now, more and more people are being intrested in learning about bitcoin. However if people take bitcoin as a way of earning money/investment than some may hate if they loss in their practice to do bitcoin trading. Actually not only monetary value, real life application of blockchain technology/bitcoin have lots of potential and it is quite sure in coming future this intrest and market demand will be quite high.
