One lesson can be learnt here, do not open shoutbox/trollbox when trading.
Just stick to your plan. Plan your trade, and trade our plan.
Correct, I can't remember what trading platform removes their trollbox because of what people are shouting, which influence a lot of traders to buy coins that they shouldn't and they bitch how they were convinced, similar to what the OP has experienced. I also was once a victim as well, I think in Yobit, when I was just starting my journey into trading.
You should have your entry and exit strategy to begin with, and just really stick to it no matter how the market moves. I'm sure with what the OP has experienced, it will be a hard lessons to swallow. Just learn from your mistakes and I really doubt that he can recover his funds. Goodluck.
