Instead, you create a Hedge vault with 1,000 SOL (worth $150,000 if the SOL price is $150). You take out a loan of 50,000 USH, which is pegged to USD so you can make your purchase. A year later, SOL has doubled to $300! Your collateral is now worth $300,000 and your debt is still $50,000, so your vault is worth $250,000. You've made a profit of $150,000, meaning you can buy yourself a second Tesla or keep the SOL in the vault until you decide to close it.
