Hello there, A large portion of the predictions allow you to win real tokens without taking any risk! So you can win real Stx tokens by finishing in the top 500 of the leaderboard or by predicting correctly on sponsored predictions that offer real token rewards. You can withdraw such tokens as you win them, you can also add your own tokens to the platform that you find on exchanges, or if you prefer you can buy Stx tokens on the platform through the Changelly gateway.
