I was scammed at least 3 times. It was when I was inexperienced and poorly versed in projects. I believed people and then they lied to me and took my investments 
You are very lucky if you have just received a fraud project three times if I almost every project that I follow has the potential for fraud, my analysis is wrong or indeed my fate is out of luck because I worked on a long duration project so that there were only a few projects and could scam because the token hasn't been distributed until now.
