If you want to transact large volumes in either USD or BTC on our site then you must verify yourself for AML/KYC reasons.
I think it would be much better if the exchanges didn't use vague terms like "large volumes". People are being asked to ID/verify for transactions which are well below the AML threshold for mandatory reporting so it would be better if the exchanges didn't imply that only large transactions are subject to AML/CTF laws. In many places the reality is that the banks at which the exchanges hold their accounts containing user funds can require the exchanges to identify the individuals behind transactions to and from those accounts at any time, whether or not those transactions are above the AML threshold amount, and that complying with such requests is a condition of them holding a bank account.
At this point in time it would probably be easier if all of the exchanges required new users to ID when first opening an account. Their may have been a time when exchanged hoped that they'd be able to fly under the radar and not be required to ID their customers but it's been apparent for some time that their banks are going to force AML/CTF compliance and their is little to be gained by pretending otherwise. It's a reality which users might not like, but expecting the exchanges to risk permanent closure by non-compliance is not reasonable - they want to stay in business and users also want exchanges to continue existing.
