Why a bonus pool instead of just paying everything daily?

Because the bonus pool incentivizes 14-day continuous attendance — which is what Google's fraud check requires. Testers who miss days lose access to bonus; the unclaimed bonus redistributes to full-attendance testers.

What's the practical difference between Karma and T-Coin payouts?

The distribution math is identical. The only difference is final destination: Karma stays inside TestHive; T-Coin can withdraw to PayPal.

How much does a tester actually earn per Campaign?

On a 1,000 T-Coin Campaign with 12 full-attendance C-level testers: each tester earns ~66 T-Coin = ~$0.66. Higher-level testers can earn 10-30% more via their level multiplier.

How TestHive distributes tester rewards (the simple version)

The fund split

Let's walk through what happens to 1,000 T-Coin when you publish a Campaign.

You publish:                   1,000 T-Coin
    ↓
Platform takes 20%:              200 T-Coin → TestHive (platform fee)
Remaining for testers:           800 T-Coin → tester reward pool
    ↓
Pool splits 3:1:
    Daily pool (75%):            600 T-Coin
    Bonus pool (25%):            200 T-Coin

How the daily pool flows

The 600 T-Coin daily pool divides across all possible tester-days in the Campaign:

600 ÷ (12 testers × 14 days) = 600 ÷ 168 ≈ 3.57 T-Coin per tester per approved day

Rounded down (we don't pay fractional T-Coin per day):

Per approved day, per tester: ~3 T-Coin baseline
At day 14 if everyone hit full attendance: a level-weighted redistribution lifts payouts to the actual pool allocation (~50 T-Coin per tester at C level)

The mechanics: tester sees a "pending" balance that grows day-by-day from approvals. At settlement, the system recomputes each tester's daily total by their level weight, and the difference between approved-day baseline and weighted total gets paid as a top-up.

How the bonus pool flows

The 200 T-Coin bonus is only for full-attendance testers (approved 14/14 days):

Full-attendance testers share 200 T-Coin in proportion to their level weights.

If 12 testers all hit full attendance at level C:

Total weight = 12 × 1.00 = 12
Each tester's bonus = floor(200 × 1.00 / 12) = 16 T-Coin

If a mix: 6 C-level + 6 S-level all full attendance:

Total weight = 6 × 1.00 + 6 × 1.10 = 12.60
C-level bonus per tester: floor(200 × 1.00 / 12.60) = 15 T-Coin
S-level bonus per tester: floor(200 × 1.10 / 12.60) = 17 T-Coin

Level weights at a glance

Level	Multiplier
C (new)	1.00×
B	1.02×
A	1.05×
S	1.10×
SS	1.15×
SSS	1.20×
SSSS	1.30×

What testers actually earn

Approximate per-tester payout on a 1,000 T-Coin Campaign with 12 full-attendance testers, all C-level:

Per-tester daily total: ~50 T-Coin (3 × 14 + delta-up from pool)
Per-tester bonus:       ~16 T-Coin (200 ÷ 12)
Per-tester total:       ~66 T-Coin = ~$0.66 cash equivalent

Higher-tier testers earn more — SSSS testers in this scenario take home ~$0.85 (about 30% more).

What if testers drop out

If only 8 testers full-attend out of 12 (4 partial):

Partial testers keep their approved-day baseline earnings (~3 T-Coin × days attended)
Full-attendance testers split the remainder of the daily pool + the full bonus pool
Net: each full-attendance tester earns ~89 T-Coin instead of ~66

This higher payout when others drop is the bonus pool doing its job — paying more to the testers who saw it through. It's also why TestHive's matching incentive structure favors reliability.

What does NOT happen

❌ Daily payments aren't immediate to your PayPal. They land in your TestHive wallet first. Cross 2,000 T-Coin to withdraw.
❌ The platform's 20% does NOT get added back to the pool later. It's the one-time recruitment + operations + fraud-insurance fee.
❌ Karma and T-Coin do NOT cross-convert. They're separate currencies with separate pools.
