Ok, suddenly the casino you're playing asks you for proof of income to be able to withdraw your winnings and to keep your account in good standing, your bankroll every month is $500 and you provide proof of salary that you are making $500 net every month, will they accept that proof will they accept that you are putting all your salary for gambling, will this violate the principle of gamble for fun, because you are working to gamble based on your proof income.
They will definitely accept that but not if you're salary is only $500 a month and you deposit $500 weekly that would make it questionable and the casino will ask you for more proof of income not only on your salary but other documents that will prove that you can sustain your bankroll and you are not working just to gamble, even if you're living with your parents there should be right allocation on all your basic needs.
