This made me $13,000 in 2 days.

Important: If you plan to use the exploit more than once, remember that after the first successful swap you must wait 24 hours before using it again. Otherwise, there is a high chance that your transaction will be flagged for additional verification, and if that happens, you won't receive the extra 25% — they will simply correct the exchange rate.
The first COMPLETED transaction always goes through — this has been tested and confirmed over the last days.

Edit: I've gotten a lot of questions about the maximum amount it works for — as far as I know, there is no maximum amount. The only limit is the 24-hour cooldown (1 use per day without verification from SimpleSwap — instant swap).
