Some of you may already be aware of the world of sports arbitrage and trading, others do not even know what it consists about. In a nutshell what it is, is that you lay (bet against) a given event at a exchange company like betfair, and then you bet at higher odds the same event on a different booker! This procedure is 100% risk free because you are submitting both bets on both bookers at the exact same time, whatever the outcome of the event might be, you will ALWAYS win, if you lose at betfair, you win at the 2nd booker, if you lose at the 2nd booker, you win at betfair. Very often the odds are always normalized between bookers, meaning that no great profit can be made. But every once and again the odds of certain events will have a difference greater than 10%, which will guarantee you a certain profit of 10% your original bet, NO MATTER WHAT THE OUTCOME MIGHT BE. On top of this, when you sign up on betfair an wager more than $25, you will be given a bonus of extra $25. So, if there is anyone here looking to make some easy money. What you do is this: Step 1 - Create a account on BetFair, near the bottom of the signup form you have a checkbox asking you "Do you have a promotion code?", you click on YES, and enter the following code EDITEDOUT , without this code you won't be able to earn the bonus of $25. Step 2 - Go to http://www.mbassist.co.uk/MatchedBets/TopMatches.aspx Check the matches with best rating percentage. At the moment you can see the following event with best differentiation of odds: Bradford - Stevenage - 114.06% at odds of 3.65 on the Bookie PAF.com and Lay odds of 3.2 over at Betfair. Meaning that when you back your bet on Paf.com, You are doing the following: PAF.com (you make a normal bet) $100 x 3.65 = 365 (you have a profit of $265 in this case) Betfair.com (you lay your bet, bet against the event) When you bet $100 what you are going to win, is the $100! You will have a liability at the given odds. So when you lay a bet, this is what happens $100 x 3.2 = $320 - $100 (that the backer already submitted) = $220 So when you lay $100 at odds 3.2, you will WIN $100 and you can lose $220! So, in a nuthsell what we have is this: PAF.com If you Lose, you lose - $100 (and win $100 over at betfair, profit/loss=$0) + the $25 Bonus from BetFair! = Easy risk free $25! If you Win, you win - $265 (and lose $220 over at betfair, profit/loss=$45) + $25 Bonus from BetFair = Easy risk free $70!! BetFair.com If you lose, you lose - $220 (and win $265 over at PAF.com, profit/loss = $45) + $25 Bonus = Easy risk free $70!! if you win, you win - $100 (and lose $100 over at BetFair, profit/loss = $0) + $25 Bonus = Easy risk free $25! I'm doing this example with $100 bets, you can do with higher values if you have the amount to invest, or with lower values. The thing you have to understand is, even if you went through all your savings and investing in this, you would be making a 100% RISK FREE investement! That is a investors dream as many of you surely understand. So if you have $1000 to invest in this, you could make $450 +$25 completely risk free, just don't forget to use the promotional code to be eligible to the $25 Bonus! You can also level your values so you will win the same amount out of any outcome. Step 3 Signup on PAF.com Step 4 Deposit $25+ on PAF.com Step 5 Deposit $25+ on Betfair.com (make the math beforehand in order to know what is the liability to the bet you want to make) Step 6 Apply both bets on betfair and Paf.com at the same time! Step 7 Profit! Step 8 Rinse and Repeat!!! If you have any questions, please post back here and I'll guide you through any doubts you might have.
