It makes a difference.If a successfull trader is sharing something and someone comes and mentions even in general chat thread that" this guy understands nothing....chart trading is all nonsense,trends dont work,I am a contrarian trader and I see 100 years of bear market ahead...."I am sure the successful trader will not be amused and he will start thinking why in the first place he is coming and wasting his time sharing something impartant. He has no need for publicity nor proving anything to anyone.
