Now I use ChangeNOW, in their rules, it is indicated that they can apply KYC sometimes, however, in case of refusal, they just make a refund. They say that KYC is not required if you exchange less than 10 BTC equivalent.
but your right and they are right . kyc on exchanges are optional or if you want to increase your trading limits but kyc on ico are different . they require it no matter how much youl invest on them .
