Basically, would you rather bet on the same thing again and again then regret not exploring more or explore different kinds of bets then miss out on a win?
I never bet on the same prediction. I'll try another prediction. Even if I don't win, it's no big deal. But no one likes constant losing.
Winning the lottery is hard enough. I don't think it matters whether you bet the same number of times or change it. Losing certainly makes gamblers regret it.
I don't know what motivates gamblers to bet on the same prediction over a long time. They might be testing their luck at predicting.
