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.
