So many of the casinos that do claim that they are Bitcoin casinos and still ask for KYC from there customers are missing the information in a big way that Satoshi Nakamoto dropped in the whitepaper.
Cryptocurrency is meant to be decentralized and should not be after the identities of gamblers who use there casinos. Big gamblers that know the effect KYC could pose in there privacy status will never agreed to use KYC casinos.
True, but it's very difficult for crypto gambling sites to offer complete anonymity due to regulators breathing down their necks all the time which is why they enforce KYC which is understandable upto a certain extent.
Crypto gambling sites should only ask for KYC for big amounts and if they legitimately suspect the customer without mandatorily enforcing it.
