Appreciate the explanation, this is something I should know by now but don't
1. borrow Tether
2. swap it for USDC (or stablecoin of choice)
3. wait for Tether to crash
4. pay off your Tether loan at a fraction of its original value
risk is that your tether loan will be accruing interest (currently 1.4%) so if it doesn't crash or takes too long to crash you could be liquidated. 1. borrows a large amount of money
2. use the large amount of money to do arbitrage
3. pays back the large amount of money plus any fees
4. keep profits
and it does so "atomically", so if you can't repay the loan then the transaction fails and the whole thing never happened. or you could lose money if the transaction is successful but the trade is not profitable.
