Mistakes
Chasing losses is the most common and most damaging mistake — increasing your bet size specifically to win back money you’ve already lost. This is a well-documented pattern that tends to accelerate losses rather than recover them.
Betting without a set budget is a close second. Decide what you’re willing to spend before you start, and stop when you reach that limit, regardless of whether you’re up or down.
Not shopping for odds is a mistake specific to sports betting — many bettors stick to one operator out of habit, missing better odds available elsewhere on the exact same bet.
Ignoring wagering requirements before opting into a bonus is another frequent error — always read the terms on the operator’s own site first.
