You and every friend who joins with your link receive a 150-sat booster each. You can accumulate up to 0.00007500 BTC.
Open the app and go to Invite Friends. Share your personal invite link or referral code with a friend.
Your friend signs up with your link (or enters your code during registration) and completes 5 mining sessions in the app. Free sessions count — no purchase required.
As soon as the 5th session is completed, 150 satoshis are credited to your in-app balance — and another 150 sats to your friend's.
Participation. Share your invite link or referral code from the app. Your friend must sign up using your link, or enter your code during registration, for the invite to be linked to you.
Qualification. The reward is unlocked only after your invited friend completes 5 mining sessions. No reward is granted at signup. Free mining sessions count.
Mutual reward. Once qualified, both the inviter and the invited friend receive 150 satoshis (sats) each, credited automatically to their in-app balances.
One-time per friend. Each invited friend can qualify only once. Additional sessions after the 5th do not generate additional referral rewards.
Inviter limit. Each user can receive referral rewards for up to 50 qualified invites — a lifetime total of 7,500 sats (0.00007500 BTC). Invited friends still receive their own 150-sat reward even after the inviter reaches this limit.
Fair use. Self-referrals, duplicate or fake accounts, automated signups, and multi-accounting on the same device are not eligible and may result in disqualification or account restrictions.
Security review. Accounts flagged by our fraud-prevention systems are not eligible for referral rewards. B99 reserves the right to withhold or reverse rewards obtained through abuse of the program.
Reward nature. Referral rewards are in-app Bitcoin reward credits. They are variable, not guaranteed, and have no cash value. They are not interest, yield, or investment income.
Transfers. Reward balances follow the standard transfer rules of the platform, including minimum amounts, security checks, and daily / periodic transfer limits. See our Terms of Use for details.
Program changes. B99 may modify, pause, or terminate the referral program at any time. Changes apply prospectively and do not affect rewards already credited.
Immediately after your invited friend completes their 5th mining session. Both balances are credited automatically — no claim step required.
No. Completing 5 free mining sessions is enough to qualify.
In the B99 Mining app: Profile > Invite Friends. You can copy your link or share it directly.
You will no longer receive inviter rewards, but your invited friends still receive their own 150 sats when they qualify.
