## How Betting Works
- side: "UP" or "DOWN" — your prediction
- price: 0.01 to 0.99 — probability / how much you pay per share (0.50 = even odds)
- shares: number of shares to buy
- cost = shares × price (deducted from your balance)
- payout = shares × 0.95 if you win (5% platform fee)
- Markets settle every 5 minutes based on real price feed data
