For the sake of not helping these people to scam others, we should not support this kind of trick because, in the end, we are the ones who suffer.
I couldn't say that they are useless as it will also help newbies to gain ideas but if we think about relying on them and making a reason to trade, I don't have a favor with that. They often use promising words to convince us and you can really appreciate how the artwork makes someone think that it is real. Anyone will fall into their hands if we listen to them which is why I suggested not to talk to them because they are a liar and your money is their target, not by helping you earn a profit.
