Counterparty risk, that is where the profit came from. I did the same thing, but went into it knowing what the exposure was and how to mitigate it: don't leave crypto in an exchange's hot wallet any longer than it takes to execute a trade and take profit only on exchanges that you could legally pursue in the event that they fail to execute a USD transfer. I also anticipated the debanking that followed... as far as I know I'm still blacklisted by one bank and two money transfer services. What I didn't anticipate was how many exchanges would get hacked and what that would look like to anybody who aggregated the transactions: I get cold called by actual financial institutions a few times a year, always looking to bulk up their dark pools - they somehow have it in their heads that I'm sitting on billions of dollars in BTC. They likely don't have enough of the puzzle to put together the fact that arbitrage doesn't take much when you only need three confirmation blocks - USD wire transfers were the bottleneck.
