beware of the volatility of the Market!! Good luck 🤘🤑

Can someone guide me with futures? Yesterday I did a test to understand how it works, I bought 2.5 xrps at 2.025 leveraged X20, I closed the operation when it was worth 2.17... according to the pnl it said I would earn more than 100%. But when I closed the operation I only made 30 cents. My doubt is how exactly is what I will earn calculated? Those 30 cents of profit I would have obtained without leveraging anything.
What do I not understand? 🤔
