...So if you know some other genuine source for best Trading Signals let me know.
Most owners of such channels earn money by subscribing, not trading. Since it is quite difficult to make money on trading, it is therefore easier and safer to give signals to others. It is for this reason that we see a huge number of offers from those who want to sell their trading signals.
Trading is difficult for a newbie but once they learn to master it, that must be time that they can make a living out of it. I think trading group can't get a lot of subscribers if the owners itself is not good at trading. We can't say that they will just get their signals from other sources because they still can't identify it if it was a good signal or not.
There might be a big number of groups but they are mostly fake. They are only trying their luck to fool newbie traders. Good thing that messaging group such as telegram are now doing an action to to ban those scam groups in their platform. They also got triggered when people call their app a nest of scammers.
