One way to know a fake team is through a project that doesn't look feasible,just laden with promises and high expectations that you damn well know for sure that a new coin wouldn't be able to achieve this..
Yeah, better to stay away from projects which promise about high profits, bright future of token price. Whenever i read promises like these, it sounds like a ponzi scheme, i quit.
Projects which prefer to talk about their products and technology are more worth to trust.
