Everyone who is skeptical about this, I understand your point.
My clients were mostly from direct interaction. And I am not saying that I am the best, or I do really well, but what I do promise is that I have a solid reason for whatever trades I take.

And I know that I can be wrong, which is why I factor that in, for any trades that I suggest. That's the only reason I am confident about any trades that I give to my client and tell them what we will do if we are wrong!
