Successfully completing the Finale of The Diamond Casino Heist will also earn you The Diamond Strike Vest, as a bonus. Casino Cashiers, seemingly imbued with the Thanksgiving spirit, are generously doling out triple the usual daily amount of Chips this week.
In Diamond Casino Heist, you can get a maximum of 3.6 million and minimum of 2.1 million. When you do it for the first time, you will get only cash and hence 2.1 million. Any more attempts can range from 2.1 Million(cash) to 3.6 Million (Diamonds).
