Staking on folks finance utilizing collateral

I am considering staking with folks finance but am slightly confused with how the leverage works. I see that I can borrow 4x to gain a better apy, but it comes with a liquidation margin of 11.7% or so and it says it is low risk. However, this seems very risky to me. Could someone explain the risks of this to me and if it is worth it or not? Is there a better way to gain 10% apy without having such a small liquidation margin?
