The people that hate bitcoin are usually people who are either trying to get the price lower or thinks it is worthless or it's gonna die out. I personally use bitcoin very extensively.
I do not think that there are people who hate bitcoin. Maybe just have such cryptocurrency who do not use or do not even know of its existence. But to hate, it's very strong.
They dont hate bitcoin maybe they just really dont understand what is bitcoin until they have found it is very useful and they can also make a real money with bitcoin . And how people will hate bitcoin if they dont know so much about it's existence and what they can do with i'm if they found it very amazingly useful they will loved to have it .
