Go to MYX DEX: https://app.myx.finance/trade and open a minimum trade of $100 worth of volume on the USDC pairs (you can use leverage to reach this volume). You can go long or short, depending on yourpreference.

Be sure to only select the Trade option, and make sure you are logged into MYX with the same wallet as your Galxe account.

Note: If you don't have $100 in your wallet, you can still trade! Use leverage to grow a smaller amount (e.g., $20) into $100 by applying up to 5x leverage.
