Pick a round
One opens every five minutes, and every hour. Each asks a single question: where is Bitcoin at the close?

Three steps, before the clock runs out
Take a side
Up or Down, from 1 MUSD. What you pay is the chance itself, so there is nobody to fill your order.
Get paid at the close
The chain prints the price and the contract pays. Cash out early at any time before the close.
Settled at —, from the chain's own price
02
Or just ask.
No chart to read. Will Bitcoin be above a price later today? Answer yes or no.
03
Be the other side of every bet.
The pool takes the other side of every round. It keeps the stakes and the 1% fee from losing bets, and pays the winners.
04
Check every word of this.
Nothing here asks to be trusted. Each of these is something you can read on the chain yourself.

Read the code that holds the money and prices every bet.

Settlement uses the BTC price Mezo's validators agree on every block, not a feed we run.
A late price refunds everyone
If no print lands within 60 seconds of a close, the round voids and every stake goes back.
The pool can always leave
Pausing stops new bets and deposits. Withdrawals and payouts are never paused.

Questions.
What do I need to start?
A wallet on Mezo and some MUSD. On testnet both are free: connect, and the site sends you 20 test MUSD and the few cents of BTC that gas costs.
How is the price of a bet decided?
The contract prices each side from the time left and Bitcoin's volatility, the same maths a short-dated option uses. You pay the chance plus a 1% fee, so a 40% chance costs about 40¢ for every 1 MUSD it pays.
Can I get out before the close?
Yes. Every open bet shows a cash-out price that moves with Bitcoin; take it any time before the round closes.
What if Bitcoin lands exactly on the line?
Up pays strictly above the line, so a close exactly on it pays Down.
Is this real money?
Not yet. Renqun runs on Mezo testnet, where MUSD is free test money and nothing is at stake. Mainnet waits on an audit.
