The second best heist for you to accept is the Cay Perico Heist, which was added close to the end of 2020. Here is a breakdown of the payout players will receive from the heist on different modes. You can receive $2,843,500 at the hardest difficulty and $2,585,000 at the lowest difficulty. Although, this is not always available, with the next best option being gold. You can lower it to normal, but the rewards go down to $3,290,000, which isn’t too bad if you can finish the normal difficulty mission at a more reliable frequency than the harder one. Of the available options, diamonds offer the highest potential payout, with a final cut being $3,619,000, and this is at the hardest difficulty. There are several targets available, from straight cash to diamonds. The Diamond Casino was made for players to take big risks and walk away with huge rewards. Below is a list of the highest paying heists in GTA. As mentioned, having friends can help you finish the objectives of the heist, but also, it makes playing on hard mode easier which then provides more payout in the end. Heists are a quick way to make big bucks in GTA Online, whether it be solo or with a couple of friends.
