Betting bots promise hands-free profits, but most fail within months, and the causes are rarely the code itself.

The most common killer is overfitting: a model tuned to perfection on past data that collapses on future matches because it learned noise instead of signal.

Other fatal mistakes include ignoring the bookmaker's margin, underestimating stake limits and account restrictions, and running a bot with no risk controls, so one bad run wipes out the bankroll.

The bots that survive share the same traits: realistic backtests, modest expectations, strict bankroll rules, constant monitoring, and a human ready to switch them off.
