When someone you invite buys their first package, you each receive 20% of that package's hash power for 3 months. There is no limit on how many friends you invite.
Open the app and tap Invite. 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 buys their first hash package. Only the first purchase counts.
20% of that package's hash power is added to your account, and another 20% to your friend's. It begins 8 days after the purchase completes and runs for 3 months.
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 when your invited friend completes their first hash package purchase. Signing up alone does not qualify, and free mining sessions do not qualify.
Mutual reward. Both the inviter and the invited friend receive bonus hash power equal to 20% of the purchased package's hash power, added automatically to their accounts.
Start and duration. Bonus hash power begins 8 days after the purchase is completed and runs for 3 months from that start date. The 8-day hold covers the app store refund window.
First purchase only. Each invited friend generates a reward only once, on their first completed purchase. Later purchases by the same friend do not generate additional referral rewards.
No inviter limit. There is no cap on the number of friends you can invite, and no cap on the total bonus hash power you can receive from the program.
Single level. Rewards are single-level. You receive a reward for the people you invite directly, not for people they later invite.
Refunds and reversals. If the qualifying purchase is refunded, charged back, or otherwise reversed, both referral rewards from that purchase are cancelled — including one that has already started.
Reward nature. The referral reward is bonus hash power, not a cash or satoshi payment. It contributes to your mining rewards for as long as it is active. It is not interest, yield, or investment income, and it has no cash value on its own.
What it does not change. Referral hash power does not generate payback, and it does not change your transfer minimum. Transfer limits are based on your own package purchases, not on referral rewards.
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.
Program changes. B99 may modify, pause, or terminate the referral program at any time. Changes apply prospectively and do not affect rewards already credited. See our Terms of Use for the full terms.
8 days after your friend's purchase is completed. Until then the app shows it as pending. Once it starts, it runs for 3 months.
It covers the app store refund window. If the purchase is refunded during that period, the reward is cancelled before it ever starts.
Yes. The reward is tied to their first hash package purchase. Signing up or mining for free does not qualify.
No. Only their first completed purchase generates a reward.
No. There is no cap on invites, and no cap on the total bonus hash power you can hold from the program.
No. Your transfer minimum is based on your own package purchases. Referral hash power increases your mining power but does not change that minimum.
In the B99 Mining app: tap Invite on the dashboard, or open Profile > Invite Friends. You can copy your link or share it directly.
Referral rewards are promotional bonus hash power granted inside the app. They are not cash, not a satoshi payment, and cannot be withdrawn on their own. Mining rewards produced by bonus hash power are variable and not guaranteed. B99 Mining is a cloud-based mining simulation platform; referral rewards do not represent earnings, interest, or investment returns. The program may be modified or discontinued at any time. Abuse of the program may result in loss of rewards and account restrictions.
