Best strategy is to put 10 euros on 4 or 5 teams to win 60 or 70 euros, and then you can increase your bet and reduce number of teams. I won a lot of money like that. And you can start following NBA league, you can make good money betting on players( bookmakers put a limit on players points and you play either more or less than that), quote is 1.85. If you start following NBA league a little bit, injuries and stuff like that, you can manage to win when you put 10 euros on 3 or 4 players.
