It just started when a person talk about trading without knowledge and encouraging people to trade in order to earn daily. Yes, it was indeed not possible but this is not for newbies and it was not really understood by them. Because what they think is that when they are trading, they will earn money instantly. That was the biggest about trading and those people who asked people to join. But I think, there is a quote " trade with risk" - that will mean something if we are going to understand it and even do searches.
