Clean Out Your Friends List
For context, I'm at 17.8k net worth. I got really tired of getting tiny heist amounts, and it was taking multiple days of rolling 1000s of dice to get enough cash to upgrade one board, so I went through my friends list and deleted like 50 people with under 8k net worth, all of whom I did not interact with aside from attacking each other. Like 35 of those people had 1-4k net worth.
I am progressing so much faster ever since I did this. I think I'm getting higher cash rewards on rolls and the heists are 100% larger now. Now that I think of it, the game rarely ever let me shutdown/heist my friends with 10-70k networth. As I was looking through my friends list, I noticed it would almost always choose my lowest ranking friends as the people to heist/attack. Now that they're not there, it doesn't have a choice except to give me bigger payouts.
In conclusion, if you're struggling with getting cash, it might be a good idea to delete the lowest ranking players from your friends list. Obviously don't delete your friends lol, but take off all the random people.
This might be common sense, but it took me awhile to catch onto it, so hopefully this helps someone else. 🫶🏻
