# Referrals (3-level CRS)
> Earn CRS from your team's mining: 20% / 10% / 5% across three levels.
The Bini App has a **3-level CRS referral** system documented here. It is **separate** from the [Binibit Exchange R0–R8 staking referrals](/bini-token/referral-levels), which work on staking rewards rather than CRS mining.
Don't confuse the two — same brand, different mechanics, different reward currency.
## Headline
| Level | Cut of team's base mining |
| ------------------------------- | ------------------------: |
| L1 (direct) | 20% |
| L2 (their referrals) | 10% |
| L3 (their referrals' referrals) | 5% |
You earn CRS as your team mines. The percentages apply to **base mining only** (10K CRS/hour × 24h × user count, before lesson bonuses).
## How it works
1. You invite a user via your unique referral link (in Profile menu)
2. They sign up through your link → become your Level-1 referral
3. They mine CRS in their app → you earn 20% of their base mining as CRS
4. If they invite others → those become your Level-2 referrals (you earn 10%)
5. And so on for Level-3
Active referral rule: a referral counts toward your earnings only if they are **actively mining** (claiming regularly).
## Active referral rate
Per the canonical economy model, **20% of invited users become active referrals**.
* If you invite 100 people, expect \~20 active referrals
* Active = claiming on the regular cadence
The 80% inactive rate is built into the simulation — it's not a problem with the system, just realistic engagement loss.
## Daily cap
To prevent sybil farming, the **maximum referral CRS** you can earn per day is:
```
Referral CRS/day cap = 500,000 CRS
```
This kicks in around **250 active referrals at 2 claims/day**. Beyond that, more referrals don't add CRS to your daily total (they still count for level/social purposes).
## Concrete examples
How referrals accelerate your progression:
| Active refs | Daily referral CRS | Days to all-lessons-L10 (vs solo 109) |
| -------------------: | -----------------: | ------------------------------------: |
| 0 (solo) | 0 | 109 |
| 10 | 160,000 | 99 |
| 20 | 320,000 | 90 |
| 100 (capped at 500K) | 500,000 | 88 |
| 250+ (capped) | 500,000 | 88 |
Beyond \~100 active refs, the cap dampens further benefit. The system rewards quality of referrals up to a point, then plateaus.
See [Tokenomics → Simulation](/tokenomics/simulation) for full projections.
## What you cannot earn from referrals
Referrals only share **base mining**. They do **not** give you a cut of:
* Their lesson-bonus mining
* Their daily calendar rewards
* Their bridge transactions
* Their lottery winnings
* Their staking rewards (those are R0-R8 — different system)
This separation keeps the math simple and prevents abuse.
## Strategy
* **Quality over quantity.** A few active refs > many inactive
* **Help refs onboard.** Active rate is the multiplier. Helping 5 friends become regulars beats spam-inviting 100
* **Hit the cap.** Once you reach \~250 active refs (at 500K CRS/day), the system gives no marginal benefit on referral CRS
* **Refer and stake separately.** Bini App referrals (here) don't impact Binibit Exchange referrals (R0-R8). They are independent systems
## Tokenomics impact
Referral CRS comes from the Rewards pool emission, allocated to the Bini App's mining mechanic. The 500K/day cap × Total active referrers × 365 days bounds the maximum referral payout per year.
The cap also prevents the worst-case "100K invited accounts farming forever" scenario.
