Many of the telegram groups which give signals are run by the same people, I have noticed on multiple occasions of the groups giving the same signals. Many of the groups also conduct coordinated pump and dumps, and they usually send it in all the groups to gather a greater audience. Although some of the signals turn out to be correct, always do your own research before making a trade.
Signals turns out to be correct then it do only have 2 possible scenarios which those are purely manipulated or just a pure coincidence. This is why I don't really trust up these kind of signals given not only on telegram groups but even on this forum itself I cant easily entrust my money to those signals.I do have my own mind to have my own analysis. Getting up some preference isn't bad as long you do know how to deal yourself on such decision.
