What he is saying has some form of relevance, as most people who call themselves experts are really not saying anything that people don't already know about, and most of them are just doing it and spreading prediction and information just to influence the market in their own interest, so if one expert starts talking about a currency and parsing it and saying that it is good and will rise in the future, that is because he wants people that follow him to invest in it and than it will actually rise and he will get the profit from it, and if he gets paid by a company to say the same thing about their coin he will do it, even without knowing its background or whether it is a scam or not.
