Red Dead Online, the online multiplayer mode of Red Dead Redemption 2, has finally gone live in its beta yesterday, at least for those who purchased one of the game’s Special Editions, allowing players to finally experience the game’s mechanics in an online environment. The mode also features plenty of content that can only be accessed by spending Gold Bars, and it seems like it takes some time to earn a single one by playing through the game regularly.

Reddit user UnavailableIDs calculated that it takes 500 minutes, around 8 hours and 20 minutes, to get a single Gold Bar if each completed series rewards players with 0.02 nuggets. 100 nuggets are required to make a Gold Bar.
