I don't have any good or bad opinion for such groups but I have lost my 100% capital in my initial days just because I used to make trade decisions based on the suggestions of the troll box. Most of the time it caused a huge loss in my trades, almost each and every time I invested randomly and it was bad timing of entry and exit in pump and dump processes.
I won't blame pump & dump schemes or even those troll box users because it was me who blindly took decisions and lost my capital so instead of blaming someone else, we must build awareness about mature trading practices.
I want to share one of my favorite quotes by Robert Downey Jr.
“Listen, smile, agree, and then do whatever the f*** you were gonna do anyway.”
This is how I function since I have come across this quote. I appreciate that you do not put the burden of your actions on other’s shoulders. That’s brave of you. In order to grow and learn, we are supposed to make mistakes and they are proof that at least we are trying but many don’t.
