For the past few days changelly has implemented new draconian KYC and AML rules that extort users into sending personal information or lose their money (good profit for changelly). There are posts all over reddit about this
Not only do they not allow you to cancel your transaction (like XAPO etc all over exchanges) after you send in your documents it will take weeks if not forever for verification. This is 100% money grabbing scheme.

PS: They do not warn users about the document requirements before you do the transaction and according to their team there is no way to get your money back. They are making excellent profit off this
EDIT 1:
Changelly said this: "We value our customers’ anonymity, so we ask for KYC only if the transaction is detected as suspicious. Besides, the user will see the warning about transaction being subject for KYC check before the final step of the transaction. We are transparent and straightforward about our intentions."
The support team are very misinformed, there is no warning whatsoever and I invite you all to check for yourself. I created multiple new orders with very high amounts, no warning. This is a blatant lie.
