We are now in a era where scam devs don't care about anonymity anymore, now they aren't willing to hide their faces, they will come out in the open, throw you some videos on YouTube and still run away with your money, if you are a newbie you need to have the following in mind when researching projects.
4. High volume on the listed exchange doesn't make a project clean from going scam.
Maybe people will always have a different opinion and there's nothing wrong with that. My general view If a project is already listed on the top 100 exchanges, it doesn't make it a scam.
My own experience having invested in projects listed on the top 100 exchanges is still safe and I think everyone is doing it. In the end, it is up to each one to believe it or not.
