There is a lot of low-quality information on the Internet and if you plan to study the crypto-currency market yourself, you need to be very selective. It will be much easier if you are trained by more experienced traders.
Information is information. There is nothing called good or bad quality unless you have some yardstick of measuring them as good or bad. I believe you are talking about the FUD that is made in the market. Its a part of the market itself. Without FUD there would be no panic sellers who help trading who are waiting to get in at the proper time.
If you have the opportunity to be trained by more experienced traders, then do it. In most cases, this is much more effective than self-study.
Thats seems absurd. If someone was more trained they would use their knowledge to gain profits and not let it go to waste. Considering the person has time to use them that is. I would say self-study is better but you need to compare and contrast yourself with other traders to get an edge
