How much money does tech n9ne make a year?

Well based on this quote from N9ne, I would have to say somewhere approximately $200,000-$800,000 per album drop and popularity.

"100% independant I'm the f*ing' boss, I sold 80,000 off a quotable in The Source,

The hood is not stupid, we know the mathematics,

I made double what I would going Gold on Atlantic."

"And that's the reason that I only trust my fam,

40,000 records sold, 400 grand,

F* a middle man, I won't pay anyone else,

I'll bootleg it and sell it to the streets my self"
