Gold Bars are the hardest currency to come by in the game and can be used in the store to buy card packs, Energy Drinks bundles, and time skips.

You can also use them to automatically buy any resources you're lacking when trying to upgrade characters or hangouts.

You can get more Gold Bars by:

• Completing the IRS showdown and reaching the Gold Bars rewards;
• Hitting Hacking bonuses on businesses - low chance;
• Completing goals - some of them have Gold Bars on their rewards;
• Logging in to your Facebook account for the first time within Rob the Rich settings menu;
• Buying certain offers or Gold Bars bundles in the store;
• Completing Events milestones(at least in most of the events).
