Nope, there I disagree strongly. Just google any of these names. David Harding; Bill Dunn; John W. Henry; Ed Seykota; Keith Campbell and Jerry Parker, there are more, but this more than suffices for now. Their portfolio incorporate all different asset classes and they trade millions of dollars. I am using the same core idea in my strategy. Forget about pips an dollar return every month - the challenge is to make a consistent growth % every month.
I agree with you that it should preferably not be your main source of income. But if you can invest say 5k and make 10% on that every month. In ten months the fund has paid for itself and from there your $500 a month income is free money. As far as the safety goes, we all know nothing in forex is guaranteed, but trading with stops and carefully monitoring during the day and monthly withdrawals is the most we as traders can do.
Well, the fact that you disagree doesn't change the real matter of things, hope you can agree at least to this postulate.
And all the persons in your list might be professional money managers, who definitely know 'fishing' well, so they can feel fish in the water, they have decent rods and all the other stuff, so OK, you might go and 'hire' them to fish with your rods too and if you are lucky they will bring you food constantly. The question is how many rods can they manage to fish with? If they are as good as you say, why do they manage only millions and not billions? What happens when 'big guys' google them and decide to give them more millions to manage? Will they still be that good? :)
