You cannot make profits if you bet small and with smaller bankroll.
If you want to make small Profit, then you need to have atleast 10 times more the profit amount in your bankroll.
Moreover from my personal experience, whenever i play a Casino game, majority time the house wins.
So i have completely shifted to sportsbetting, and find myself lucky in some smaller events.
Moreover a Gambler lose more money, when they go to recover the loss, Better when you see that, you are already losing some money, better to stop Gambling and make the mind cool for next bet.
