A KYC at an online casino is not a big problem in itself. Many players have gotten used to that. It only becomes a problem if players refuse to provide this information. Often referred to as the terms and conditions, they almost always state that the casino reserves the right to perform the KYC, which will happen. Then it is only a matter of time before that takes place. A KYC can, however, be carried out in 24 hours. I often wonder how casinos check such information, since they don't have access to the local authorities for information
it is not a big problem if you are not really complying to your own privacy but if you are a true crypto user and use to it? then KYC providing will always be an issue as we knew that this is a gambling site that mostly being target of bad elements and we also knew that our KYC will be in bridge if the site explode so why need to play in KYC requiring site when we can play without giving single details of us?
and besides are you really a gambler mate? if does then you know that in crypto we love to keep our privacy on and choose only the site without KYC.
I am pretty sure that most cryptocurrency casinos would prefer to not ask for that information as they know the average user does not like to provide those details, especially in a market that has a significant portion of users that are against any form of KYC, but unfortunately many of those casinos have to do it whether because they are dealing with fiat or because their casino license forces them to do so, it is a shame but I think we may get to the point in which no casino is exempt of asking for that information under some circumstances.
