This is the main argument against those signal sellers who claim to provide a hundred percent accurate signals to their premium users. But these stupids cannot use their own signals to make money. They sell their signals instead. But unfortunately, people still fall for these scams and this is why we see new advertisements everyday. We cannot expect everyone to be veterans about these things. There are people who don't know about trading at all and when they first see the ads, they get greedy and fall for these scams.
