YBN Nahmir has been beefing with Adin Ross over a boxing match that may or may not happen.

During the back and forth, Ross doubted Nahmir had 100K to his name.

"Nahmir, you’re not worth $100,000. You fell off, you suck at music. You failed your music career," he said. "Nahmir, you’re nothing, you’re nobody and your career sucks. He wanted 100 bands to fight. You are nowhere near 100 bands. And again, Kick paid Carti $2 mill. Hey, at least I got $2 mill to pay. You’re broke, f*ck you."

Nahmir fired back at Ross and all of the haters with his net worth:  $4 million, according to Google.

"A young n*gga worth in the millions Don't le me start the popping it," he typed.

Four million isn't the kind of net worth most rappers would flex.

Then again, Nahmir is only 24, and his only studio album sold 4K in the first week and failed to chart in any territory.

Which kind of calls into question that net worth ...
