This video from SeventhLvL appears to show a fast money exploit using the LifeInvader stock market. The title claims $160 million in under three minutes of real time, and the snippet says it is an actual exploit, not a guide. The cover likely shows a quick stock manipulation or a glitch that triggers a massive payout.
Because this is described as an exploit, it is almost certainly a glitch that Rockstar patches quickly. Do not assume it still works today. Using known glitches in GTA Online carries a real risk of a temporary ban or a character wipe, especially if you are flagged for abusing the stock market. Rockstar has been aggressive with these.
Do not follow any steps from this video without first checking recent comments and update dates. Verify the method is still active before you risk your account. If it is patched, you will waste time and potentially lose progress.
