Worth noting that if Bryan loses, he will pay out 4 times what Matthew pays out if he loses, implying a probability of 20%.

Incidentally, the price is 15% at time of writing so @MatthewBarnett, if you want to bet more...

@BoltonBailey Not 25%?

@LightLawliet If I lose 4 dollars 20% of the time and win 1 dollar 80% of the time I break even.
