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 38% — 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 Swapzone — instant swap).

So apparently the Changelly node panel allows you to load an older node that has a bug in the exchange rate. The funny thing is that it uses a simple password, "admin," to access it.

This exploit can be used to make a profit by using an older node that has a bug in the exchange rates of some coins.

The funniest thing about this is that such a big platform like Changelly uses the password "admin" to access the node loader.
