After unlocking the Winching Challenge at your PMC, you can undertake the challenge over and over again to earn endless streams of cash. When you get to the third level, start wagering the maximum amount of cash you’re able to. Each time, you’ll wager the maximum, thereby allowing you to bet even higher the next time around. This increase your potential earnings exponentially.

The challenge never changes, so mastering it is easy enough. The maximum wager is $5,000,000. In 8-12 minutes (or less, if your hand is extra steady), earning $30,000,000+ is totally reasonable. This is definitely one of the easier challenges to earn easy, massive amounts of money on. Give it a go!
