ok real talk is there actually a money cheat for gta 5 story mode??

Straight answer, no. There has never been a money cheat in GTA 5, story mode or online, and there never will be. Every video or site promising a working money code is clickbait or a survey scam, so don't go entering your details anywhere for one. What actually works in story mode is the Lester assassination missions: buy the right stocks before each hit and you can turn all three characters into millionaires. Online it's legit grinding, heists and businesses, nothing you type in. Anyone selling you a code is selling you nothing.
