I wouldn't trust such groups. At most, I would use them to help me. Sometimes you just can not see a good time of call in a particular coin, and such a group helps you. Before you buy a coin on the signal I do my analysis and already decide whether to go or not. Previously, I also used one paid channel for trading, but the signals did not always work out positions. After that I decided to start studying fundamental and technical analysis. Now part of the signals I filter out and the risk of losing part of the funds decreased.
