This video from GRAVESIGHT GAMING claims to show the easiest and fastest solo car dupe money glitch in GTA Online. The cover suggests a standard car duplication method, likely involving the Auto Shop or a specific garage trick.
Remember that duplication glitches are patched by Rockstar very quickly, often within days. The video may already be outdated by the time you see this page. Also, using duplication glitches carries a clear ban risk. Rockstar actively tracks suspicious garage activity and money earned through unintended methods. If you are caught, you risk a temporary suspension or a full account wipe.
Do not follow any steps without first checking the video's upload date and the comments section to see if other players confirm the method still works today. If the video is more than a week old, assume the glitch is dead. Always verify the current working status before attempting anything in your own game.
