Oh wow, I guess you're not really serious about this one. But, hmmm this is not a good attempt to convince people.

Your service seems unreasonable as you only hope to profit from someone else's random win on any bet. You may be able to tell someone if they lose that they are only 0.00001% of the people who lose based on your prediction, while you would say that your prediction is 99.9999% correct if they win and make a profit.

I hope this kind of service is not worth the risk because if it is true then you will be more likely to invite relatives, family, friends, or anyone else in your place (IRL) to make a profit. Then what is this?
