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.
its true for those who cant really understand bitcoin and not interested in bitcoin will be hating this coin for sure but if theres an interest or they can understand how to use it then they lovin it like us we fully understand how bitcoin works.
I agree those people hates bitcoins because they really don't know how to use bitcoins properly and they are not getting benefits into it. But I don't agree with the people who doesn't have interest with bitcoins, since they are not interested at all and why they are going to hate bitcoins? For what reason do they need to do that.
Some people trade the bitcoin. When they want to buy more cheaply, they will talk down the bitcoin.
