At the point where the Bitcoin was converted into bank account funds. There's a reason why money laundering is a criminal specialty. He needed to stop stealing and fencing the goods before getting caught, wait a few months or years without doing anything shady at all, then start dripping the ill-gotten gains into his account alongside an entirely legitimate cashflow, a little bit at a time. Buying a mansion and a roadster out of the blue is an "stupid criminals get caught; all criminals are stupid" type of move. Even if all you know of crime comes from the movie theater and television set, you'd know that after the airport job in Goodfellas, some of the guys got whacked for violating the "don't buy anything!" edict. In Breaking Bad, the car wash and the Pollos Hermanos chicken restaurants were necessary for laundering the methamphetamine revenue. I think the mention of Bitcoin mixers was just chaff. The guy was caught because his bank tattled on him, and the IRS didn't buy his flimsy sourcing story. If he had just kept the proceeds as some variety of cryptocurrency, he might not have gotten away with it entirely, but the investigation would probably still be ongoing--the questions remaining to be answered being, of course, "how much did he steal, exactly?" and "how do we seize and forfeit those funds?" Someone might know that he was stealing something, but they wouldn't necessarily know how much.
