*This service has some KYC-related lines in their ToS. Please read below.
ChangeNOW is a non-custodial crypto-to-crypto exchange where you
can trade a large number of coins quickly, conveniently, registration-free, and
without any limits. Although it normally does not require KYC it could be that
one of your transactions is marked as suspicious and then they will require you
a KYC procedure. The suspicious transaction detection system is not public so
we can't know what may trigger this. You can get a refund to your address if you
don't want to provide your information (without KYC).
