I agree to this! being knowledgeable in things are the most important thing to make your fears and doubt gone. If your equipped enough with knowledge about something then you won't be affected to all bad news spreading around you. You need to research and study more about bitcoin if you want to overcome all of those.
I am hesitant with bitcoin at first thinking that it might be one of those MLM scams before but then due to curiosity, I research more about it. I was scammed at first joining those cloud mining sites and I learned my lesson from it. I don't know anyone personally who has involved with cryptocurrencies during that time and I am happy now that more people whom I knew personally are slowly getting engaged in bitcoin. One day, mass adoption would happen and we would be proud of being in here first then the majority.
