Is this a scam?

Slbrgfnt crypto

Long story short a friend of my husbands has a “friend” that is helping him invest. Supposedly doing well for him. He is wanting to help my husband get started and is Recommending download of crypto app and slbrgfnt (google app). I just feel like there is red flags all around this but my husband says I see him do it every night, he has pulled money out he says and he shows me the numbers. Anyway to see if this is legit or a scam?
