I've never shorted or taken out crypto loans, but you could theoretically:

- Take out a loan of USDT, using a stablecoin you trust as collateral

- Immediately trade all USDT into your stablecoin

- If the USDT price crashes, buy it up to repay the loan.

e.g. Binance lets you borrow 800k USDT with 1.23m collateral. Over 180 days, interest paid would be 36k.

Say USDT crashes and you repay your loan at 10c/USDT - you would pay at most 84k to settle the loan. You then end up with 1.94m, a 58% return on investment.

It's probably not that simple however.
