Decentralized casinos, which operate on blockchain technology, sometimes offer an alternative to traditional casinos by providing more anonymity and removing the need for KYC but obviously they are not entirely foolproof either. As with any online activity, there are inherent risks so using the reputate sites, checking in the forum... those are required.
Yes, but they ended having problems and implement the KYC if the business its doing good and starts tod evelop that "problem", for problem i mean, goverment or agencies who wants info for them and the players.
So you need to be very carefull choosing a good casino and also, making the move before they start to want the KYC done and move to another who still dont need KYC.
