Bitcoinker rewards its loyal users by giving them bonuses on their payouts. The longer you are an active user of Bitcoinker, the higher bonuses you'll get. An active user is considered a user that claimed Bitcoin directly (not by a referral) at least once in a 30 day period. If a user doesn't claim directly at least once in a 30 day period, then the seniority status is reset. You can check your seniority statistics through the check address link.
