Up Down — predict the price on a fast shared round.

1. Every round runs 30 seconds. Tap Up or Down before the countdown ring locks.
2. When it locks, the price moves and settles — you win if it finishes on your side.
3. Odds are pool-based: the side with less money bet on it pays more (the live Up Wins % / Down Wins %).
4. Your payout = your stake × the winning side's odds at settle.
