My Questions now are, Why do some people hate cryptocurrency so much? What's their back story? Did they ever lose a huge amount of money in cryptocurrency?
Yes, some people hate bitcoin because they have experienced huge losses when investing in cryptocurrencies, you could say it happened purely because of their own fault because they were too hasty when they started investing without more knowledge and did not do any research at all when they got into it. So that makes them frustrated because they lost, and finally they decide to spread FUD so that other people hate bitcoin too.
Those type of people that incurred huge losses will always paint Bitcoin in a bad light some will even equate it with the moribund Ponzi scheme MMM when they got liquidated after investing blindly without a prior knowledge of it, we also have bankers who see Bitcoin as a threat to their existence because of its feature as a store of value thus hate Bitcoin with all their might and will do everything to discourage other people investing and hodling it, despite all the backlash Bitcoin has come to stay and despite all the hate speech and other derogatory remarks wouldn't have impact on it, more adoptions is on the rise consequently it price will continue to grow or increase.
