How it works

• • Each round lasts 1 minute. Predictions close 10 seconds before the round ends.
• • Choose UP if you think BTC will rise, or DOWN if you think it will fall.
• • All predictions go into a shared pool. When the round ends, the losing side pays the winning side.
• • Your payout depends on your share of the winning pool: the fewer people on your side, the bigger your reward.
• • A round is only valid with 2+ different wallets on opposite sides. Otherwise, everyone gets a full refund with zero fees.

Jackpot

• • 1% of each valid round's volume is deposited into the on-chain Jackpot treasury.
• • Predict within the first 20 seconds of a round to earn tickets. $1 = 1 ticket.
• • Be the first or largest predictor on a side for a 2x multiplier. Both? 4x.
• • A winner is drawn daily at 9 PM ET using a Bitcoin block hash. Prize: 10% of the treasury.
• • The jackpot never zeros out — it only grows.

Zero gas fees, fully automated

• • All transactions are sponsored — you never pay gas fees.
• • Rounds settle automatically — winnings are sent to your wallet. No claim button needed.
• • Everything runs on-chain on Stacks, secured by Bitcoin.
