+20% hash power
Twenty percent of their first plan's hash power, added on top for 3 months

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.
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.

Pick the plan your friend is likely to choose. You both receive 20% of its hash power for 3 months — no reward estimates, just hash power.
Bonus hash power is credited automatically once your friend's first purchase completes. Only the first purchase counts; a refund cancels both bonuses.
