Principal is non-redeemable.

A deposit is not a recoverable account balance but a consumptive entry: once CBTC arrives it is split among referrers, stakers, and the prize pool, with no path to reclaim the principal.

Zero-sum redistribution.

The protocol creates no exogenous returns; your gains come from the principal of later participants and the market price of FAIR (off-chain). Any projected return is not a promise.

Rules are immutable, and no one can bail you out.

The contract has no owner; allocation ratios and the reward release curve are fixed on-chain, and claiming is not subject to pausing. This means no one can mint more or misappropriate funds, and it also means no one can intervene in extreme situations.

CBTC is a project token.

CBTC, the protocol's base currency, is issued by the project's own ecosystem and is not Binance's official BTCB. Its market price and liquidity are the protocol's most important external dependency; verify them yourself before entering.

Rules

Game Rules

FAIR is a fair mining protocol deployed on BSC: every deposit is 100% redistributed to participants, mining rewards are settled per epoch, and the rules are fixed on-chain and cannot be changed by anyone. This page is a complete rules overview for players.

① Deposit Split · 100% Redistribution

Every deposit is split at fixed ratios the moment it arrives: 15% referral / 45% dividend pool / 40% FOMO prize pool, all flowing back to participants with zero protocol cut. Principal is not returned; what you get is a mining share for that epoch (see Risks & Boundaries).

15%

45%

40%

15% referral commission: each of three referral tiers earns 5%
45% dividend pool: distributed to eligible FAIR stakers
40% FOMO prize pool: accumulates until an empty epoch triggers a payout

Four assets are accepted for deposit: BNB / USDT / USDC / CBTC; non-CBTC assets are automatically swapped to CBTC via PancakeSwap. The minimum vault deposit is 0.1 CBTC.

② Mining Rewards · Settled per Epoch

The system creates one Epoch every 10 minutes, releasing up to 50 FAIR per Epoch, divided among all deposits in that epoch by share: your rewards = epoch rewards × your deposit ÷ total deposits in the epoch.

The release rate follows the same halving mechanism as BTC: every 210,000 Epochs the Epoch reward halves once, and each halving cycle lasts about 3.995 years. FAIR has a hard cap of 21,000,000, with no pre-mine and no team reserve; all of it comes from mining.

Stage	Epoch Range	Release per Epoch	Approx. Calendar
1	0–209,999	50 FAIR	Jun 2026 to May 2030
2	210,000–419,999	25 FAIR	May 2030 to May 2034
3	420,000–629,999	12.5 FAIR	May 2034 to May 2038
4	630,000–839,999	6.25 FAIR	May 2038 to May 2042

If no one deposits during an entire epoch, that epoch's reward is not minted (counted as forfeited), so the actual final supply is below the theoretical hard cap. Mining rewards can be claimed anytime, or compounded in one click via Claim & Stake.

③ Staking Dividends · 45% of Deposits

Stake the FAIR you mined into the protocol to earn 45% of every subsequent deposit, pro-rated by your share of active stake (denominated in CBTC).

Dividend eligibility: stake ≥ 50 FAIR; distribution starts only when there are ≥ 10 eligible addresses globally.
Activation timing: a new stake takes effect in the next epoch.
Claim & Stake: mining rewards can be compounded in one click, requiring ≥ 50 FAIR per action; any remainder is kept claimable.
Unstaking flow: after you request an unstake, a 24-hour cooldown begins and can be cancelled anytime during it; once it ends, you claim back the FAIR. Only one unstake can be in flight at a time.
Partial unstake: both the withdrawn amount and the remaining active stake must be ≥ 50 FAIR; otherwise you can only unstake in full.

④ FOMO Prize Pool · Triggered by an Empty Epoch

40% of every deposit flows into the FOMO prize pool and keeps accumulating. As long as someone deposits in every epoch, the pool only grows; the moment an entire epoch goes by with no entries (an empty epoch), it settles immediately to the players of the previous non-empty epoch.

An empty epoch triggers settlement: players of the previous non-empty epoch share 40% by deposit share plus 10% split evenly (50% of the pool paid out in total), with the remaining 50% rolled over.

40% By share: distributed by your deposit proportion in that epoch, rewarding larger entries.
10% Split evenly: shared equally among all participating addresses in that epoch, protecting smaller players.
50% Rollover: stays in the pool to keep accumulating, waiting for the next empty epoch.

Rewards must be claimed manually, and a share from the same epoch is never paid twice. Topping up with a large deposit near an empty epoch can both block the pool's payout and make you the main beneficiary of the next one: this is strategic space inherent to the mechanism, not a bug.

⑤ 3-Tier Referral · 5% per Tier

For deposits entering through your referral link, each of the three referral tiers earns 5% (15% total), credited instantly to a claimable balance in CBTC; when the referral chain is shorter than three tiers, the missing tiers go to the protocol referral vault.

Your referrer is bound automatically on your first deposit and cannot be changed afterward.
Only in the special case of using the default referrer is there a 48-hour rebinding window, and it can be used only once.
You can register a personal referral code (4–12 alphanumeric characters, case-insensitive) to turn your referral link into a memorable short link (e.g. ?ref=BTC888). First come first served, one code per person, permanently immutable once registered.
