It's indeed great for the regular gamblers. Usually crypto casinos offer around 5 - 10% affiliate income to the referring party. So even if you share 80% of the referral income to the player and keep 20% with you, it's a win win situation for both. However, please ensure that you enter into a legal contract with the crypto casinos otherwise, some casinos may block you for generating too much referral income and citing security risk. Especially if any of your references win the jackpot or make big gains. So a legal contract is always preferred to avoid any unforeseen issues. Good initiative where both parties will be benefited.
