I would think the chin.He was in charge of the biggest family and even before he was boss he was the most powerful capo.I wonder what he did with his money?He lived in a modest home wore a bathrobe allday and didnt travel too much in his later years.
Chin was actually known for not taking a lot of money off his captains. He was already a millionaire and so didn't really need it. And you're right, he never really went anywhere. After he died, one law enforcement official was talking about what Chin got out of it. He thought it was really just the "pure power" he exercised.
