If you believe you're skilled at sports betting, enough to pick the single best game daily.. could you actually discipline yourself to bet just once per day for an entire season to prove your profitability?
Personally, I'd struggle. The urge for more action would get to me. Even starting with one game, a loss would leave me feeling unsatisfied, tempted to chase and recover immediately rather than wait for the next day.
The ability to limit your brt number to at least 1 bet per day for the entire season could help you to avoid heavy losses during this period where so many matches end in unexpected ways, so if you make multiple, that means that you as a gambler increasing your risk and drowning closer to your loses level.
