A legal contract with funds being escrowed or an insurance contract backed by a legit insurance company would be sufficient. Obviously the strategy is bs.But if he will give me 90% return on my investment to prove his point that would be a pretty good trade for me.
You guaranteed 180% returns if I run your strategy but you won't back that guarantee. That's fraudulent.
Anyhow, I am out on this strategy. You lost your chance to earn 900k on your guaranteed strategy. All you needed to do was get an insurance company to back your guarantee. But you don't believe in it enough to do this. Why should I risk my own money, when you aren't willing to do the same.
I've posted the system, so everybody can test and verify its given guarantee of 180+% profit p.a. If you find any inconsistencies so let me know.
I don't need your money. The system has been posted, it's public domain, you can test it in your lab if you wish, and if convinced you can use it freely if you can apply it in the world markets.
