The Brazilian Jiu-Jitsu world has erupted into chaos following the announcement that entrepreneur and self-proclaimed financial guru Derek Moneyberg was promoted to BJJ black belt in just 3.5 years. His rapid ascent triggered fierce debate online and in the gyms, with big names like Jake Shields, Mikey Musumeci, and Vinny Magalhaes weighing in.

Derek Moneyberg Responds to Critics

Amid the controversy, Moneyberg issued a long and defiant statement that he pinned to the top of his Instagram comments. Here is the full transcription:

I’m actually going to stop funding any BJJ people after this. I’ve never met a group of people so bifurcated. I trained thousands of hours under about 40 champions and top contenders from BJJ and Most UFC. Every one that knows me well speaks to my intelligence, hard work, and character.

But the general public in this sport is extraordinarily low functioning and it’s hopeless for them to comprehend what I actually did. They can only imagine that I’ve bribed dozens of top athletes to vouch for me.

Many real fighters and gym owners have reached out to share nice words and I don’t wish to insult them at all. That’s what martial arts is supposed to be about. I started training at age 42 to be fit, learn new skills, and be able to defend myself and my loved ones effectively when I’m in my 60’s and still traveling the world…

I never said I was the best fighter in the world, or anything of the sort. But I am a legit BJJ black belt. I’m also working on my second black belt in Kempo. I joke with my coaches that I will be a hell of well-rounded MMA fighter by the time I’m 50 😄

I’m going to focus on earning that second black belt, and a second hundred million dollars. And I’m not responding to this absurd level of jealousy and hate again. I know what I did and where my skills are and my coaches know that too. I don’t have to prove anything to some antagonistic individuals “challenging me” and hoping I’ll comment and grow their social media presence.

I do see why a lot of these individuals are poor and struggling. And I hope they choose to do better. They are not mad at me; they are mad at my success as a reflection of their relative failure. The number one thing a hater hates is himself.

To all the real martial artists that can understand what I did, I know you worked very hard too, and offer my deepest respect to you and thank you for being rational and living an honorable life.

📢 The Original Announcement

In his initial post, Moneyberg claimed:

“I got it in about 3.5 years. Zero days missed, because no excuse is good enough to give up on your goals.”

He reported over 3,000 hours of mat time and personalized instruction from “the best team in history.” He also claimed that Royce Gracie personally praised his work ethic, saying he had “done the work of ten years in three and a half.”

🥋 Jake Shields Defends the Promotion

Jake Shields, an MMA legend and Renzo Gracie black belt, supported Moneyberg, saying:

“I’ve seen him train. He’s not just showing up for photo ops. He’s putting in real work. He deserves the belt.”

🤝 Mikey Musumeci Joins In

World champion Mikey Musumeci also stepped in to defend Moneyberg:

“I’ve rolled with him. He’s legit. He works harder than most, and people need to stop gatekeeping belts just based on time-in.”

⚔️ Vinny Magalhaes and the Critics Fire Back

Vinny Magalhaes, former ADCC champ and UFC veteran, sharply criticized the promotion:

“I’ve trained world-class athletes, and none of them progressed this fast without insane natural ability and decades of grappling. Something doesn’t add up.”

🌐 Community Reactions

The wider BJJ community has mostly reacted with skepticism and even mockery. On Reddit and Instagram, many users questioned the validity of Moneyberg’s belt:

“This is an insult to everyone who spent a decade bleeding for that belt.”

Some see it as a symbol of a creeping celebrity influence and “belt buying” culture, eroding the values BJJ was built on—patience, humility, and deep-rooted progression through trials.

🎭 Final Thoughts

The Derek Moneyberg black belt saga highlights a cultural rift in the world of Brazilian Jiu-Jitsu: between purists who demand time and lineage, and those who believe that focused, obsessive training—even if unconventional—should be rewarded.

As this story continues to unfold, one thing is clear: the debate over what makes someone a legitimate black belt is far from settled.
