Take a look at some well-known people on Twitter, they will give some direction, every day to learn the knowledge of cryptocurrency, every investment before thinking, do not fear failure, find experience in failure.
If you want to learn from them, that will be okay but if you want to just follow what they said, for example, they told you to buy A coin, then you will need to think twice. We can learn from many sources, which is unlimited, as long as we want to learn and have an effort to learn. I am sure we will have our time to make a profit from trading and once we can do that, we still need to learn more to have more chances to make a bigger profit.
You are right. There is a thin line between simply following what has been said and evaluating the information acquired in order to come up with a decision. There indeed many sources to acquire knowledge beside following well-known people on Twitter, there are books, video tutorials and even demo trading. I think that traders should know that learning is a never ending process in this field, we learn new things every time.
