When I firstly heard about bitcoins I thought that its a pure scam and its not worth to invest money in it as in long run it will only give me loss so after doing some great research I found that its an genuine way of earning some extra money.
We had the same experience and thoughts about Bitcoin before. I was scammed multiple times when I was a newbie and I decided to stop using it because of that. Then after a few years, I decided to try it again but I did some research first and now I'm earning good and learn from my past mistakes to avoid being scam.
