Traders and investors should do well to ignore such news, exchanges love to promote it as it gives the impression that anyone no matter what can earn big profits while trading, however it is clear that for someone to produce those kind of results they had to take a massive risk.
However, you never hear from exchanges about all the people that took the same risk and that instead found misfortune and huge losses, as that is not good for business and it breaks the illusion they are trying to create.
That's true, I don't think I have ever seen any exchange release an information about customers that had a significant lose about a particular crypto that they have invested on. The only news that usually pops up are the ones related to huge profit made but I believe that even if they don't release such good news about huge profit, there might still be some lucky investors that is going to make profit from the coin and also some investors they will experience lose.
For example, I have actually bought a token at a high which I thought it was going to continue pumping but reverse was the case. I knew that people who bought that token at a low prices, really made profit from it.
