And of course additional steps which will lead you to "trust".
The question immediately arises: what are these steps? Scammers are very creative today. They know perfectly well which layer of investors, which advertising, needs to be influenced. An inexperienced person can easily trust a bright show from scammers with unimaginable promises of profit.
So I would rather not trust anyone. Experience comes with time, and while a person has questions and does not understand any things in checking a project that seems interesting to him, without receiving answers to them, it is not worth taking risks and believing.
Be creative too.
You write example, "without receiving answers to them, it is not worth taking risks and believing.".
Point is to not be naive and to think with your head. Especially for beginners.
