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.
Even you say "people hate bitcoin because they have experienced huge losses when investing in cryptocurrencies"! So they hate Bitcoin because they didn't invest in Bitcoin, they invested in something else!?
People hate when someone is messing with their brain! And it's what Bitcoin and crypto are doing, they are changing the way we think about the economy! So some average Joe thinks that money is only the money in his hands, and at the same time he doesn't understand where that cash coming from (or knows some basics)... How can this person understand blockchain and all the projects built on it?! So at the end of the day, it's easier to hate than to try to understand! To try to learn more about something... they just turn on "BiG Brother show" and turn off their brains!
