the longer the time you spent the more you lose, this is the truth that many gamblers won't accept at first until they realize it later.
Not true at all. High rollers have a large bankroll and because of that they almost win most of the time in their session even playing for several hours and even a whole day with only a few breaks. Even a gambler only spends a few hours in their gambling session, but risking a high bet amount per spin, then what's the sense of doing it within a short time if the risks are just the same as usual?
It's not about how long should we spend time on gambling but rather just knowing how to stop for a while.
I also agree that this is not always true and only a few times is.I know from personal experience that when playing slot machines with bet 0.10 as a minimum and have a bankroll of 300 dollars chances are much higher than to play 10 dollars with the same bet.The reason being that a smaller bank roll most of the times will end faster,much faster before you hit a substantial win compared to playing with 300 dollars.So this brings it down to,the longer you play with a higher bet the higher the chances to lose the same as playing a short amount of time with low bet.So we cannot assess it based on bet and bankroll rather than the time spent.
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.
