I have been scammed when i was 16 years old, they said when I invest some money, they will give it to me times two of the money that I invested to them. I didn't check the background of that person and I didn't ask opinions to other people. Then I invest some of my money because I'm expecting the times two of my income but when I give it to them, they just blocked me in all communication. Even though I was scammed, I learned a lot of things like always check the background and don't forget to ask opinions to other people to avoid being scammed.
