The zinocoin.com system offers a dual-level referral program. Your reward is 5% of every investment a direct referral of yours makes and 1% of deposits made by your second-level (indirect) referrals. To receive referral rewards, you don't need a deposit of your own. Just create an account and invite friends by giving them your referral link. When your referral makes a deposit, the commission amount will immediately arrive at your account.
