If you are looking to make millions from betting soccer, or any sport at that rate, the road will be a very tough one to hoe.
But if you are looking to just win and make some money each week, the path is there for you. Start with some favorites and build a small parlay.
For example, on the first day of UEFA Euro 2020 qualification, there were five teams that were heavy favorites: Belgium, Croatia, Netherlands, Macedonia, and Northern Ireland. All had odds of -225 or higher, up to -900. If you bet all of the teams singly, you would have won, but would have had to risk a lot of money to do so.
But a five-team parlay using Belgium money line (ML), Croatia money line ML, Netherlands money line ML, Macedonia money line ML, and Northern Ireland money line ML paid out at +250, or 2.5 to 1.
Those odds would have won you a return of $350 (or pounds or euros) on a $100 bet. With that bank, you could now take a little larger risk the next day, and either increase your bankroll, or drop it down slightly, but still be in the plus category. The whole goal is to be winning, and if you can string together enough winners, you can have yourself a good week.
If you really want to try to win a huge sum, try betting 10-15 team parlays using the favorites. One lucky bettor at Parx Casino won $150,000 on a $25 20-team parlay in March of 2019. It can be done.
