1️⃣ Up/Down

Up/Down is the quickest and easiest out of the four games: initially only one cryptocurrency (BTC) and only two options - up or down. A player needs to guess if the price will be higher or lower at a certain point from the moment when the timer is reset.

There’s no need to name a specific price target: if you select “Up” and the future price is above the initial price even by $0.01, you win.

A user needs to lock up an amount of USDT on Arbitrum to play. All the submitted funds are automatically grouped into two pools: Up and Down. Users can view how much money and how many players are in each pool, and what the potential payout is in case of winning.

There’s also a timer showing the time remaining until the end of the game round. Players have limited time to make their decision and click a button, after which they have to wait for the result.

The reward is determined by the size of one’s bid and the sizes of the two pools. The losing pool is divided among the winners after the 10% platform fee is deducted.

📌 Example: The initial BTC price is 67,500; some minutes later it reaches $67,550, so those who voted “Up” win. At the end of the cycle, the Up pool has 100 users and $1500 in USDT, while the Down pool has 80 users and 1200 USDT. Bob’s Up bid was $25, or 1/60 of the total Up pool. Therefore, his reward will be (taking into account the 10% platform fee) 1/60 of the Down pool size, or 1200*0.99/60=$18.

That’s a 72% profit rate on a 0.105% price move. If Bob was margin trading instead of using XYRO, he would need to use 800x leverage – and would almost certainly get liquidated on intraday volatility. In other words, the Up/Down provides better returns than any major leverage trading platform.

December 2024 update: we’ve made some corrections to the fee calculation algorithm for Up/Down - hopefully you’ll find that the result of each game is now even more fair.
