No, you can't cash out: myths and scam warnings
Newsclick's explainer flags a common misconception: in-game naira is virtual. Players cannot make money in the game and withdraw it as real cash.
There is also no official App Store or Google Play app. Guides list lagoslife.app (and the original lagoslife.eliysites.com) as the real addresses. Treat any download, 'mod', or 'free naira' site with suspicion and never share your password.
Also add an email to your account. Without one, a forgotten password cannot be reset.
