+20% hash power
Twenty percent of their first plan's hash power, added on top for 3 months
Invite a friend. Both get more power.
When someone you invite buys their first plan, you each receive 20% of that plan's hash power for 3 months. Invite as many friends as you like — there is no limit.
How the program works
Share your personal invite link from the app. When your friend signs up with it and buys their first plan, bonus hash power is added to both accounts — automatically, nothing else to do. The bonus starts 8 days after the purchase and runs for 3 months.

Frequently Asked Questions
Here are quick answers to the most common questions.
Need more details? Visit our Help center
When does the reward start?
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.
Why is there an 8-day wait?
It covers the app store refund window. If the purchase is refunded during that period, the reward is cancelled before it ever starts.
Does my friend need to buy something?
Yes. The reward is tied to their first plan purchase. Signing up or mining for free does not qualify.
Do I get a reward every time they buy?
No. Only their first completed purchase generates a reward.
Is there a limit on how many friends I can invite?
No. There is no cap on invites, and no cap on the total bonus hash power you can hold from the program.
Does referral hash power lower my transfer minimum?
No. Your transfer minimum is based on your own plan purchases. Referral hash power increases your mining power but does not change that minimum.
Where do I find my invite link?
In the B99 Mining app: tap Invite on the dashboard, or open Profile → Invite Friends. You can copy your link or share it directly.
