These types of casinos are the final destination for people who care about their privacy. But still, there are some risks. If they ever hit a big multiplier and then want to withdraw their big wins, they will have to complete the KYC or leave their winnings.
I believe there is nothing without risk in this world. It's always a trade-off between what you can accept to lose and what you want to gain. Free lunch is nonexistent.
We all know, everyone who are playing casino in online with cryptocurrency want the privacy without any (KYC). We doing the KYC just because is being asked or mostly people who are chasing rewards (example, like stake did forcing user KYC and giving user 50 or 250$ depends on the rank).
I'd love to see a detailed research on this. I know the value of such research is probably small but it will be interesting to read. We can run a poll on this forum if we have the time, although the result is probably biased anyway.
When you mention identity theft, I don't know how that come into play in this case or you are suggesting that people could perform KYC with the documents of others?
I believe he mainly refers to fraud when talking about why KYC is important. I can see this if we view this from the POV of the casino. But yeah, there are a lot of cases where documents get faked and a business approves a fake identity verification.
