And this brings us full circle to how important it is to have several accounts. As was easy to see from the example above, a betting pro always moves in the percentage range. The bookmaker gave a 50% chance, but the bettor has to win 53% of the time. In the end, these small nuances decide whether you win or lose and whether you become a betting pro at TonyBet or not?
A Real-World Odds Example
Here is an interesting example:
Bookmaker XY, which has a reputation for having very accurate odds, offers odds of 1.9 (Team A) and 1.9 (Team B) on the betting market. XY thus states that the odds for each team are 50%.
The betting professional now needs odds that justify betting on this event. With a 50% probability, odds of 2.0 or higher would be correspondingly profitable. The calculation is (1/0.5 = 2.0). The more accounts a prospective professional has, the higher the chance of finding odds above 2.0. Even if no references are drawn from the Asian odds, it is extremely important to always catch the best possible odds. If only 1.9 is taken instead of a possible 2.0, it is almost impossible to end up in the black at the end of the year. If you also take into account the effect of the interest rate, this small difference will cost you half a fortune in the long run.
The Concept of Line Shopping
This concept is of course not new, but became known in America as “line shopping”. Handicappers realized early on that it was well worth going from gambling store to gambling store to compare the various spreads or moneylines.
Why Odds Make a Huge Difference

A simple calculation illustrates how important it is to get the best possible odds:
If 1,000 bets of €10 each are made per year at odds of 2.0, then €10,000 is invested to win €20,000.
If 1,000 bets of €10 per year are placed at odds of 1.90, then €10,000 is invested to win €19,000.
That’s a whole €1,000. It goes without saying that it will be very difficult to win an additional €1,000 with stakes of €10 per bet.
A Shortcut to Grow Your Bankroll
Before the analysis aspect comes to the fore, we would like to briefly point out that there is a very simple tip on how to grow your bankroll quickly, especially at the beginning, in order to take the next step towards becoming a betting pro.
Bonus Hunting Explained
The concept is called Bonus Hunting / Whoring. This term also originates from the American language, as is not difficult to recognize. In principle, the aim is to use as many bookmaker bonus programs as possible. If you do this cleverly, you can multiply your bankroll very quickly and automatically have several accounts with various bookmakers in order to get the best possible odds. However, winnings from bonus offers in the first few months should only be used to build up your own bankroll. No conclusions can be drawn from these winnings that the same winnings will be made in the future.
