Of course KYC is not too difficult, but some of them are reluctant to do KYC because they are afraid of their data. In fact, the KYC policy of almost all major casino sites has implemented it so that every gambler should not be too afraid to do KYC. Responsible gambling of course by complying with the rules that apply and it must be followed for all users.
Yes indeed and it should not be that difficult for user to decide to agree to do KYC, It has something to do with trust but there are casinos that asked KYC, that goes with something unusual like this thread from one user
" You also need to provide a photo of a document confirming your location along with your document, like a receipt from a coffee shop"
I remember there was a thread of one user being asked by the casino to take a picture of himself standing besides the street sign that is on the user's documents.
I'm glad that casinos' like 1win are straightforward on what they are asking of their users when it comes to KYC.
