Gold is the real-money currency in AdVenture Capitalist, and can only be obtained through gameplay during events, by earning certain Everything Unlocks on Earth or the Moon, or doing a hard reset on Earth. Doing hard reset will reward you with 5000 Gold, and the reward can only be earned once.
Gold is not required to play the game. It merely makes the game a little easier/faster, via Gold Upgrades. It also sometimes adds small aesthetic changes along with the boosts.
