There is a reason it is called a trollbox bro, the answer is damn obvious. Nobody in there is trying to help you, they're trying to convince you to buy their trash bags that nobody wants. A troll box is possibly the worst place you can possibly go to seeking advice, and you will likely lose a lot of money if you let those idiots get into your head.
Yes, you are right.
you can use the trollbox for your benefit, you do not need to listen to the advice that is in the trollbox, but you can use the information that is in the trollbox for your benefit. for example, someone in the trollbox says that altcoin Z is going up a lot, you can go see if this is true and you can do research on altcoin and decide whether it's worth buying or not. Even something like trollbox can be very useful if you know how to use it properly, you can also use the trollbox as a way to refresh your head, this will decrease your stress
