uniswap and trezor wallet exchange have no kyc when ive used them
Trezor wallet uses their party exchanges for that exchange function e.g. Changelly, ChangeNow, Shapeshift, and coinswitch and trust me, they will request for KYC at any time they want
Yes, KYC requirements on these instant exchanges usually asked when the value reaches on KYC limit required amount per transaction. So maybe @roemer only exchange smaller amount but it's proper to say they don't ask KYC because as per above mentioned, they can ask for it anytime.
