Most of these scam projects are also built by the same scammers under different names and profiles. It's important that you can recognize some faces in the team before putting money into the project unless of course, they have a big market cap already.
Sometimes they don't put the same face, they just steal a different identity just to scam people. We should be aware that, if we are educated with these scams, we will likely succeed in investing as there's a lot of great projects that could potentially give our investors a good return.
New projects are risky, but if they succeed, you will enjoy a big profit, but it's still up to you if you are willing to gamble and how big the risk you are willing to take.
