Look at the dev, if it's an a Anonymous or newbie dev then there's a really bad sign .

Add to that big premines or something like a 24 hour PoW phase and the odds of a scam go through the roof.

In the end experience will make you better at this but that means you'll have to lose some money.

The fact you're already asking the right questions is a good sign so hopefully you won't lose much.

Good luck!
