Don't buy the government's story! KYC wasn't some altruistic move. Casinos loved anonymity just as much as gamblers did. It kept the high rollers happy and the money flowing freely. But someone higher up got spooked. They saw all that untraceable cash and thought, "hey, that's OUR tax revenue disappearing!" Suddenly, KYC became the golden rule. Coincidence? You decide.
They scrambled to put KYC in place, not because they care about you, or to fight the financing of terrorism, or some other crap like that, but because they want their share.
