If you want to bet on the winner - you will get small odds. And the winner still can lose. It is not interesting to make such bets - your win is too small comparing with risk. With odd about 1.3 after your three wins on loss will return you to the start.
Of course it doesn`t mean that it is wonderful idea to bet big odds or losers. But you can choose another events with more balanced teams and more interesting odds.
Those small odds can hurt you in the long run. If you're always betting on 1.30, yeah it might win most of the time but you need to keep a really high win rate to stay profitable. Around 80% or more.
The question is: can you really maintain that consistently? Just do the simple math, if you're betting $100, you’d need to win 4 straight bets at 1.30 just to be slightly ahead. Sounds easy on paper, but in reality, it's a lot harder than it looks.
I have an answer for such question. I made an experiment with small sum - i bet all events with odd less 1.10. As the result i lost my bankroll in two weeks, if i remember right. If you will choose events in top-leagues your chance would be higher, but i don`t ready to spend time trying not to lose. I prefer to analyze other events and try to catch 2,5+ odds.
