Disclaimer: Not promoting betting in any way just a casual bet to see how it turns out nothing else. Do not bet for the sake of winning money, it's never a good idea.
This is curious question, but isn't that really high risk low reward bet? You have 50% chance of losing 10 while by winning you win like 2 pounds. Unless Guild had at least like 2 multiplier. Obv 10 pounds isn't that much to begin with but you get the idea.
