How to Earn Infinite Money
- Travel to the east coast of Los Santos once you have two characters available. Off the shore, swim to the waypoint marked in the image below.
- Dive underwater to find a crashed airplane with a stash of money. Grab the cache, then switch characters.
- Switch characters back to your man underwater. You’ll find that his oxygen will replenish, and the money will respawn.
- Repeat as necessary. Each time you grab the stash, you’ll be rewarded with 25,000$.
