1. Head to [untrading.org/uncryptos](https://untrading.org/uncryptos), connect your wallet.&#x20;
2. Browse the marketplace (think OpenSea for unCryptos!). Check the Profit Expectancy (PE) – it shows your potential earnings based on future price rises and rewards.&#x20;
3. Spot an unBTC or unETH you like? Click“Buy - Limit,”set your amount, confirm with MetaMask. [See testnet steps](https://docs.untrading.org/tutorials/how-to-buy-and-sell-uncryptos-on-untrading.org-testnet).&#x20;
4. Ready to sell? [List your unCryptos on Racetrack](https://docs.untrading.org/tutorials/how-to-buy-and-sell-uncryptos-on-untrading.org-testnet#step-4-list-sell-and-make-changes-to-unbtc-uneth-unsol-unlink-ununi-and-un-offerings) – set your price at near the PE level (+5%, 8%... that the unCrypto token was originally set for), include PE for buyers, and confirm.&#x20;

**Why It Rocks:** Trade unCryptos with full transparency and earn Future Rewards even after selling – all on mainnet!

**Pro Tip:** Wrap your BTC into unBTC to boost your PE and maximize rewards. Let's go to the moon! 🌙
