Are there seriously enough casinos that can tolerate black chip action for extended periods of time that this can be made into a career?
At 2 units/hr, you'd need to play 100 hours a year of $100 blackjack to eek out a poverty-level living, 200 hours a year for a decent living. I don't see how this wouldn't be picked up by the casinos, especially since so many of them are owned by the same companies (even the Indian casinos).
