I agree with you, some paid groups give a signal but the main purpose of trading not only gain profit but also learn the craft in the trade. I experienced Fomo too, this is not new for many traders out there, but the time will come you will learn from mistakes.
What I have been able to understand so far is the presence of perfect knowledge and perfect information that keeps you safe and successful in the market. This perfect information comes with research and study about the market and about the technology. You can also follow some good experts and also keep an eye in the market to see the demand for which coin is high and which coin has stable prices. This is only possible to understand in the presence of good understanding.
