Any government has never collected any taxes to the user through crypto casinos and I dont think its possible either because online casino customers come from all over the world.
Yes, it is not possible. Taxes can only be collected via KYC required centralized exchanges like Coinbase.
No. The tax man dos not take a cut from crypto casinos or centralized exchanges. Thats on you, bud and gotta report those sweet gains you scored at the sports betting just like it was poker winnings. IRS is wising up to this crypto stuff, so dont think you can pull a fast one. Theyll catch up eventually. Better to play it safe and pay Uncle Sam his fair share, even if it dos not seem fair to us. Who wants an audit anyhow? Do it clean file those forms, sleep easy.
