The Instant Max Cash Glitch is great for grinding money and xp insanely fast. This Glitch is very useful since you can collect max money without a full bag. It is great for when you are robbing and there are only a few items.
To do this glitch, you have to escape the prison first. 
You may need an alt account or friend to do this glitch. Once you escape, spawn any vehicle and make your way to get a Jetpack. Getting a jetpack is not required for the Glitch, but it makes things easier. 
Once you have a jetpack, you need to make your way for any robbery. 
It’s suggested to head to the museum if you have never done the Glitch. Then, wait for someone to come and help to start the museum robbery. 
Once they arrive, start the robbery by exploding a hole and then head inside it. 
Next, grab a single item from the inside. 
Once you have an item, you need to head to any side and finish the puzzle. 
Next, wait for another person to finish their side and pull the lever. 
Once both levers are pulled, you have to head outside and make your way to any robbery. It’s suggested to go to the jewelry store next for a better result. Next, make a hole in the glass but don’t enter the store. 
Instead, you can use your jetpack. So your museum bag goes away and you can crawl. 
After that, head inside the jewelry store and stand beside any case. 
Next, you have to punch the glass case until it breaks, so the robbery starts. 
It’s how you gain a full museum bag without getting items. After that, head outside the jewelry store and go back to your vehicle. 
Finally, make your way to the collectors and earn your money. 
It’s how you finished robbing the museum for max cash with only a single item. This Glitch is very useful since you can collect max money without a full bag, it is great for when you are robbing and there are only a few items. It’s suggested to try this the next time you have a museum bag. This Glitch can be done with almost any robbery around the jailbreak map. 
It’s suggested trying the cargo plane since it gives the most. 
To do the glitch with the cargo plane, you will need to grab any crate inside the plane. 
Once you have a crate, make your way outside the plane. 
You need a keycard to get out, but you can also use the mobile cargo. 
You will be spawned outside. 
Now, make your way to any robbery to collect max cash for the crate. And repeat the same method of collecting max cash for the robbery. 
It’s how you become able to collect max cash for the cargo plane crate. Now, make your way to the cargo port and collect your money. 
It’s how you finished robbing the cargo plane for max cash with a less crate. The glitch will allow you to get a large crate value with only a small crate. This Glitch is also great for grinding money and XP insanely fast. 
Just remember to head to a second robbery before turning in your team. When doing this glitch, keep in mind that not all robberies will work. 
For example, you are unable to do the glitch with the bank and cargo ship. 
It is because whenever you finish robbing, the money does not stay like others. However, the power plant does work to get max value but it is different. To do the Glitch with the power plant, you have to hack the outside computer. 
Next, head downstairs and open the main computer but don’t start hacking. 
You will need another player or alt account for this next glitch. 
Oce opened, you need to finish the lobby and tell your friend to stay still. 
Next, once finished head back to your vehicle. Now, you will need to go to the Volcano base but don’t let your friend die or leave. And it’s how you will be able to get max uranium inside the volcano base. 
Once here, finish hacking the main computer. 
Now, wait for the value to go down to 6000 before turning the uranium in. 
Once it drops to 6000, turn in your uranium for max money. 
It’s how you will be able to turn in my uranium for max value at these bases. If you tried turning the uranium in before, it would disappear instead. This is an anti-cheat that was added to prevent players from getting the max.
