The more the better. Why wouldn't you use help provided on the net if you can. Stuff like Newscrypto that have all in one place for traders are ideal for such situations.
But he/she should also avoid some fake or not legit news that will make people FUD. Because as a trader, there's also a FUD.
But some traders don't really on news or any articles, some of them are in on technical sides, likes on chart, candle sticks, etc.
Thst's why you are also correct, the more the better. Just beware on those fake articles/news especially. If you really into technical side, focus on it.
This is why I prefer to trust in technical analysis than in fundamental analysis, anyone can try to create a fake news to try to move the markets and if enough people believe it then you are going to take the wrong decision just because you believed in a fake news, I prefer to watch the charts and let them tell me what they want me to do because at least when it comes to the charts if someone wants to manipulate the market they need to be willing to risk several millions of dollars to manipulate it and very few people can do that.
