If you don't want to worry about the BTC price and don't have more BTC available, you can just increase the collateral ratio by decreasing the amount borrowed.
Also, I don't think it's fair to let you hold more BTC that I hold USDC, because I don't think you're trusted enough for that.
This doesn't make any sense, I can say same about you.
Also if you borrow for 2 months, the repaid amount is closer to the actual collateral value than the amount borrowed. But if you want me to hold the same value as you and let the rest to DarkStar_ I'm fine too, I just need a guarantee to at least not lose anything.
The capital will be deployed in my trade, so I can't guarantee that I will be able to decrease the amount borrowed at a moment's notice. As you said, you want a guarantee, and while this is a secured loan, it is not entirely risk free (if you believe the price of BTC might fall 20%+ in a few weeks).
Thank you anyway.
