I am one of them. I usually bet on underdogs majority of the time and favorites minority of the time in all kinds of sports because the underdog odds usually provide more value(Based on my experience).

The strategy that I usually use is wagering small amounts and building an accumulator instead of wagering big amounts on single underdog bets. This strategy helped me earn decent profits in the long-term.

I achieved more success by betting on underdogs in Asian Soccer leagues.
