How Long Does it Take to Make $2.1 Billion Starting From $0 in GTA 5 Story Mode? (All 3 Characters)

This video from LKG tests how long it takes to grind from zero to $2.1 billion across all three characters in GTA 5 Story Mode. The title and snippet suggest a full playthrough or optimized grind, not a quick cheat. If the method relies on stock market manipulation (like the Lester Assassination missions), that is a legitimate in-game feature with no ban risk. However, if the video uses a glitch to duplicate money or bypass mission payouts, those can be patched and may corrupt your save file. Since the snippet does not specify the method, assume it could be a mix of both. Glitches in story mode do not carry an online ban risk, but they can break progression. Before committing time, check the video's upload date and recent comments to confirm the method still works.
