In my opinion, uing Blockchain + KYC for self-exclusion is a strong idea because it combines transparency with identity verification. Blockchain alone can flag addictive gambling behavior, but players can bypass it by creating new wallets. With KYC, casinos can link activity to a verified identity, making it harder to evade restrictions. This is typically efficient whereas a global system where flagged addresses or identities are recognized across platforms could truly reduce problem gambling.
But the question is, will the government really put effort into figuring out who’s addicted or not? I doubt they’d spend their time on that. What they’ll focus on is anti–money laundering, investing in tech and systems to monitor transactions.
As for gambling addiction, they’ll probably just issue warnings or run educational campaigns, but they won’t go deeper since gambling addiction itself isn’t a crime.
