From July 15 , Kukoin introduces mandatory KYC: "Starting from July 15, 2023 (UTC), newly registered users must complete their KYC in order to use KuCoin's products and services" - https://www.kucoin.com/announcement/enhancement-of-kucoin-customer-identification-and-verification-program
And this means that if there are still any exchanges without KYC, then we can expect that after some time, a mandatory KYC will also be introduced there.
