Those who do not understand and not interested on bitcoins are the one who do not like it. I do not think that people would hate it they just do not understand it.
Many people doesn't really know what bitcoin is, how does it works and where to get it. So because of their laziness they are not able to do some research.
And don't forget those people who have failed with bitcoins then they are also one of the haters of bitcoins they are still not moving on to their failure.
It is better if they are going to move forward and start another way to use bitcoin.
I agree because the fact that we are just 1% users of bitcoin compared to the total population of the world the big disparity will already prove, however we should not be contented on that figures instead we have to help promote bitcoin at our way to help the economy progress and more people will adopt.
