This opportunity works well for investors who want long exposure to Bitcoin (BTC). Keep in mind, your returns are impacted by the price of BTC and this pool's yield.
Risks include multiple smart contract risks, the potential depeg of tBTC, and potential bad debt due to untimely liquidations of collateral assets.
Your yield primarily comes from the interest rates paid by borrowers who leverage the assets you've supplied for trading or farming. The more your asset is borrowed, the higher the interest that accrues back to you. The yield can change depending on borrow volume.
