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.
1. Visible team members don't mean they are scam free.
2. A audited smart contract project can still scam you.
3. Scammers can spend a lot on their website to make it look attractive just to make you invest your money.
4. High volume on the listed exchange doesn't make a project clean from going scam.
The points you mention are very helpful both for beginners and for those who are experienced in investing in new projects. Because not everyone has the understanding you describe here, especially beginners who usually tend to get caught up in new fraudulent projects that offer huge profits by buying a low price later when the coin is listed on an exchange with a high price. So be very careful in investing in new projects should always do your own research and don't be easily provoked.
