And what prevents to undergo procedure KYC on top 5 exchanges? And why did you decide that top 10 would introduce a mandatory procedure? And why did this question arise in general, dont you trust them? Then you should not give your passport at the airport or in the bank, because there is exactly the same chance that your data will be sold to someone. And why there is no Idex or Ddex in the list? I would say, any decentralised exchange dont need KYC procedure. Even bancor dont need it.
