# Abstract

Prediction Arena is a fun, community-driven platform where you use free virtual chips to predict price moves for major cryptocurrencies like BTC, ETH, SOL, ADA, and AVAX over three timeframes: 5-minute sprints, 1-hour runs and 24-hour marathons. You’ll see our AI’s probability forecast then place your bet on Up or Down. Winning wagers earn chips (minus a small fee that varies by timeframe) which you can wager again or down the road, swap for real ARENA tokens.
