Common Sports Betting Mistakes
None of these are exotic - they're the ordinary mistakes that show up in the math over time.
Chasing losses with bigger stakes
Increasing stake size after a loss abandons a staking plan exactly when discipline matters most.
Ignoring the bookmaker's margin
Comparing a bet only against a gut feeling overstates how much edge is really there.
Treating accumulators as free upside
Stacking many legs into one bet compounds both variance and margin.
Not tracking results
Without a record of stakes and returns, it's impossible to tell variance apart from an actual edge or leak.
