This is correct and I agree with it. Also, most people who tend to follow this routes are those who had a different mindsets which could be as a result of what they heard and so on, thus when whey join the crypto space they will be easily moved by hype, what analysts says etc. In my own opinion, I think it is far better to first seek for the knowledge of the crypto space which of course covers a whole lot of questions thus knowing what is obtainable through this way making the right decisions. Lastly, I wouldn't say the first point is to be watched out more than others, NO, all have the same devastating effects thus should be avoided at all costs through doing the right thing.
