I have never joined any trading groups or signals, but my friends provide me with information about price movements and coin analysis which is the topic of telegram groups.
As I know, for traders who want to make quick profits without doing their own analysis, they will join the signal, many benefits can be obtained such as technical analysis that we did not know before, we will understand it.
Losses are not just wrong trading signals, they are just predictions, we can only analyze and the market determines when the coin price will go up
