Especially if you are new to gambling and have started to profit from gambling. Everything goes great once you start winning and that's exactly what casinos want. You increase your income and continue to gamble with higher balances. Because most people think that if they try gambling long enough, they'll make a big hit.
Do you mean we should gamble for few times, then withdraw all of the money and never comeback to the casino anymore?
Well you're not always making profit when you gamble for few times in the beginning, it's all about luck and there's no such winning set up for new gambler. There's a rule about minimum rollover, if you not met it you will get asked to submit KYC because the security flag your activity is suspicious.
