Thank you all for your response and good comments.
Usually my bid does not exceed$ 30 for one Express.
But since this is my first public bet, I decided to make the maximum before your eyes, or lose. But this will not stop me during this week I will collect all the bets and calculate the profit or loss as a percentage of my Deposit of 1000$

Manchester United - West Ham United - Both teams to score YES (+)
Liverpool FC - Chelsea FC   UNDER (3.5)  (Started)
Torino - Hellas Verona UNDER (2.5) (Start soon)
