It’s one of the most profitable businesses. Doing it with a friend is much safer than doing it alone, because griefers will be griefers. It’s similar to any of the Biker Drug Businesses in GTA Online. Moonshine gets created, then you sell it for profit. The higher you upgrade your equipment, the better your payout. The maximum payout for a 3 star batch I’ve gotten is $246. Like I said, safer with a friend, but profitable, it’s definitely one of the “must-haves” if you want good money in the game.
