Quite agree with your submission, this is actually one of the reasons why I always prefer betting on sports anytime I have a low bankroll, over playing slot or casino games.
Slot or casino games are not games to be played wit a small bankroll, for like you said, the gambler must have ended up with an empty bankroll before he or she gets an opportunity to win some good multipliers or free/bonus spins which could help or assist the player to winning a handsome amount of money.
For me, and in general though, I still believe winning in slot games isnt much about how much time a gambler spends playing, but it's more about how much lucky the gambler is, but then, it still makes more sense to play slot games with good enough bankroll than with a tiny one.
Slot gambling does not rely on game analysis and you will not be able to measure your luck with gambling if you gamble with a low bankroll. You need to know that the chance of getting lucky in slot gambling is very low and there is no guarantee that luck can cover previous gambling losses. I agree more with your opinion that this step is effective in reducing gambling time by choosing a sports betting scheme and you will avoid gambling addiction because you only gamble when your favorite team is playing or other matches but you will be sure that the team has a chance of winning the match .
