Trading needs a lot of researches and analysis like financial analysis,market analysis.Unless you know the previous and current market situation of a coin,it will not be able to find the coin which is most under valued.
its need complicated analysis and not everyone can do this.even an expert ,they learn all about analysis more than years before could earn money and profits.
Your statement is wrong but I think you want to say it right. We can't call an expert if that person is not capable of the skills of being expert right? I guess what you want to say is that before they became experts, they started to someone who doesn't know this kind of things. Earning money is hard work, but if you are a good worker and enjoying what you are doing, it is not that hard really.
