You don't offer any reason to invest with you, since you only pay back 50% on a 2x bet.
So why don't we make our own bet, and instead of getting only 1.5x prize like we would from you, we get 2x for ourselves.
And you don't offer any risk management or insurance, you say "obviously you can lose all your money"
So there is really no reason to bet with you. Sorry, Ill pass
