This page covers a video from Mr Snook titled "How to get a lot of Money in GTA 5 Story Mode (Unlimited Money Glitch)." Based on the title and snippet, the video appears to demonstrate a glitch for generating unlimited cash in the single-player story mode, not GTA Online.
Be aware that story mode glitches are less likely to get you banned, but they are often patched quickly by Rockstar. The specific method shown may no longer work. The video claims to unlock "secrets" for massive wealth, but without watching it, we cannot confirm the exact steps or payout amounts.
If you are looking for legitimate story mode money, consider the stock market missions with Lester or completing the main heists. For this glitch, verify the video's upload date and read recent comments to see if the method is still active before spending time on it.
