Here's a really simple straightforward coin toss strategy:
I think I'll have better luck without it lol :P

This presumes somebody can pay you that much. The expected win is then 3100−12100⋅100−100(1−12100)≈4⋅10193100−12100⋅100−100(1−12100)≈4⋅1019 To maybe make this less unbelievable, imagine a two round game. Clearly on the last throw, you want to bet all you have, increasing your expected fortune by 50%50%. On the first throw, then your expectation is 1.5(x−S2+x+2S2)=1.5(x+S2)1.5(x−S2+x+2S2)=1.5(x+S2) which (given the rules) is maximized when S=xS=x. Alternately, your result is the same if you interchange the two flips. Since you should be all on the last flip, you should on the first as well.
