That's a good strategy but it doesn't work every time. Sometimes there's a minimum limit for withdrawals.
In order to reach the minimum limit we try to gamble more and often lose but that's of course for smaller bets.
So the best would be to leave gambling for the day when you have gained enough profits.
Come back some other day and try your luck again.
When you deposit to casinos, afford your loses from betting.
I am doubtful that more winners than losers who are betting on casinos. More losers for sure on casinos and more losers than winners on crypto exchanges and crypto market.
So if you feel your money is small and can not be withdrawn by min limit, let's use it to bet, afford lose but of course hope for big win.
