No body would be interested in this kind of offer not to talk of the conditions you're giving, since you're a good and professional trader i expect you to have build your own trading platform through which you would have acquired enough profits from past trading experience you had, someone like me cannot trust you or have you control my trading account.
I have read his reply in a different topic, and although he seems honest and not scammer, but nevertheless, within 5 months, nothing has changed in his pocket, even if he had sufficient skill, there would be no real change in the individual's investments.
Come to think of it yourself, can you employ someone like that or make a partnership agreement with such a person, also take a look to his conditions of offer, that alone sounds ridiculous, if he's truly experience in trading, how comes he has no capital again to continue with trading, isn't this alone a factor to be considered by not having any partnership with him?
I advise you to get a loan and then try to pay off the trading profits. Ask one of your friends or relatives to give you a loan without interest and for a repayment period of 3 months. Test your abilities and if you can pay, share your experience, and then others may get excited and give you money.
This also is a bad option to take, even though it's a no interest loan, it's still not good because he can trade and loose the entire money at once or gradually and how do you expect him to get the money refunded back, if the friends and family will help in this kind situation, they should raise money for a free donation for him and not to lend him and put him in debt.
