KYC should only be mandated if the service itself is handling FIAT and has to obide by FIAT rules. meaning its a registered money service business
as for KYC in general for p2p exchanges. it should be an option the seller should choose to ensure identity of th buyer so that the seller can provide identity of the buyer to banks.. to prove the buyer was the buyer, if the buyer tries to do chargeback scamming.
i see too many times that non-regulated exchanges demand KYC, under the pretense of trying to appear official, but in reality they are gathering info to sell that info on
Thank you so much for your feedback!
