There seems to be a bug on Changelly that lets you get significantly more crypto than you should when swapping Bitcoin to a different crypto.
It appears to be related to a backend module thats still active in their system. When BTC is selected as the sending currency, you receive around 25 - 27% more of the destination coin than expected. Other currencies dont trigger it.
Just make sure to stay under $5,000 per swap to avoid KYC.
Someone put together a short write-up with all the details here:
