What are Seniority Bonuses?
Our faucet rewards its loyal users by giving them bonuses on their payouts. The longer you are an active user, the higher bonuses you’ll get. An active user is considered a user that claimed Bitcoin directly (not as 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 his seniority stats are reset. You can check your seniority stats at any given moment through your profile page on the top right of the nav bar.
