Yes, we shouldn't rely on other signals because definitely it will hurt us a lot because previously I have followed many signals which at last didn't help me to make money, I have lost a lot of money through this group. It is really a very good way, to ban those Signal groups.
That is why we need to learn some basics lessons of trading, so we don't rely on them to trade because many of them are not giving the right signals to their members. Some paid groups that I have been watched in the past giving the same information without any difference, so I conclude that they joined in many signal groups, and they share with their private groups. They claim that the signal comes from their analyst people, so they guarantee that the signals are valid.
From that, I always warn my friends not to join the paid group signal, and it is better to analyze the market by ourselves. We can find the coin by our analysis so we can get more than 1 coin, and we can try to get a bigger profit from many coins.
