There are 32000 plus members in this forum. Some of them, aren't traders any longer.
However, if there is a participation of 10% monthly at $50 that is about 160,000 dollars.
100,000 for first place, 30,000 for second and the same amount for third.
Well, if you are that good you will win in a year about, 1,200,000.
By the way, no robots.
We also can invite the participation of others forum members like Hanover, Digital, Codemeister among others. The more the better. The organizer should charge a fee from the monthly jackpot to cover cost plus a reasonable profit. This is in general.
I know it is not that simple. Just a vision.
