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.
When you had a job for the monthly income from some companies over a period of 2 years.Then the account was enroll as the salary account.So then if you withdraw the money from casino it was seems to be the funds from your salary.Even it may not from the income of salary,this case make to pass such things due to the old transaction.
