Casinos are created with the sole purpose , and that is to make the owner rich and famous and there are so much expectation from each casino when they started to open each casino.
but of course there are chances that players or gambler won over casino houses but this is at least 1 out of 10 to happen so yeah casino will not let us gain while they are losing.
Well, referral and affiliate bonuses are a good start if you're looking for some rewards from the casino even though you keep on losing to them. You need to be a pro in getting people register under you or you will not reap these benefits obviously. Even though the casino wins over you in the long run, if you have a well-established referral/affiliate list, you'll still get a nice little trickle of money on other people's deposits.
yup I know that is one point of how to gain another stuff from casino while the reality we are losing commonly .
and yes there are so much to gain from bonuses if you know where to play and where to deposit.
and also referral is one thing that most of us using now because if you are not a gambler constantly then you will earn from those referral programs.
