Step 1: Choose a Market

Find a market you are interested in. For this example, let's say: "Will Bitcoin hit $100k in 2025?"

Step 2: Select Outcome

Click on the outcome you believe in.

  • Yes: You profit if Bitcoin hits $100k.
  • No: You profit if it doesn't.

Step 3: Enter Amount

In the trading panel (usually on the right or bottom):

  1. Make sure the Buy tab is selected.
  2. Enter the amount of USDC you want to bet (e.g., 100 USDC).
  3. Review the Avg Price and Shares.
    • Example: 100 USDC at 50¢ price = 200 Shares.
    • Potential Return: $200 (if you win).
    • Potential Profit: $100 (Return - Cost).

Step 4: Confirm Trade

  1. Click Buy.
  2. If it's your first time, you may need to Enable USDC (one-time signature).
  3. Sign the transaction in your wallet (or just click confirm if using Email/Magic).
  4. Wait a few seconds for the "Trade Complete" notification.

Congratulations! You now have skin in the game.
