Overview of Floyd Mayweather’s Transition from Boxing to Business
Floyd Mayweather’s career beyond boxing has been as eventful as his performance in the ring.
Known for his flamboyant lifestyle and entrepreneurial flair, Mayweather has leveraged his celebrity status to endorse a variety of business ventures.

However, his forays into the world of finance and crypto have not been free from scrutiny.
Mayweather’s name carries considerable weight, making any association with his projects newsworthy. His high‑profile endorsements of cryptocurrency projects have drawn regulatory attention.
However, multiple lawsuits and financial disputes have painted a complex picture of his business dealings.
These diverse endeavors, however, have also led to allegations that some of these ventures were not entirely above board—a theme that plays a central role in the narrative behind the “Floyd Mayweather scam.”
The Centra Tech ICO Controversy
In 2017, during the height of the cryptocurrency boom, Mayweather endorsed Centra Tech’s Initial Coin Offering (ICO).
Promoted as a revolutionary financial platform, Centra Tech quickly attracted attention from both investors and regulatory bodies.
Mayweather was paid $100,000 for his promotion, which he failed to disclose. This omission was a clear violation of the SEC’s anti‑touting rules.
The U.S. Securities and Exchange Commission (SEC) however, took issue with the undisclosed endorsement, eventually forcing Mayweather to settle.
As a result, he paid disgorgement, penalties, and interest, and accepted a three‑year ban from endorsing any other securities.
This incident is a textbook case of how failing to adhere to transparency guidelines can lead to severe legal repercussions, not just for crypto startups but for any celebrity endorsers working in financial markets.
The case has since become an example cited by regulators and financial experts alike when cautioning against undisclosed endorsements.
Quick Tip: Always disclose any compensated endorsements to maintain trust with your audience and abide by legal guidelines.

The EthereumMax Lawsuit: When Celebrity Endorsements Backfire
In 2021, a high‑profile class‑action lawsuit was filed against Floyd Mayweather alongside other celebrities—including Kim Kardashian and Paul Pierce—over their promotion of a cryptocurrency called EthereumMax (EMAX).

The lawsuit accused the trio of participating in a coordinated effort to inflate EMAX’s value through deceptive marketing tactics.
Critics argued that the celebrities, by endorsing EMAX without sufficient due diligence, misled investors about the potential returns and safety of the investment.
The lawsuit claimed that the orchestrated endorsements artificially drove up the token’s price, leading to steep losses for investors when the hype inevitably subsided.
The controversy sparked discussions among investors regarding the ethical responsibilities of high‑profile personalities when promoting financial products.
So, what can we learn from this?
The EthereumMax case underlines the immense responsibility that comes with celebrity endorsements.
It demonstrates how the impact of a well‑known figure can translate into significant financial decisions by the public—often without full disclosure of inherent risks.

Other Financial Disputes
Mayweather’s ventures have not been limited to the crypto sphere. Several other high‑profile disputes have also cast a shadow over his post‐boxing career.
The Logan Paul Payment Dispute
Following their 2021 exhibition match, controversy emerged when Logan Paul claimed that Mayweather owed him approximately $5 million from the fight’s proceeds.
According to Paul, this shortfall impacted his personal finances and larger business plans.
Claims centered around incomplete or delayed payments which, if proven, could have major contractual and reputational implications.
Mayweather publicly denied owing any additional sums, and the dispute remains emblematic of the complexities inherent in high‑stakes celebrity financial contracts.
Jewelry Fraud Lawsuit
In another legal twist, a Miami‐based jeweler filed a lawsuit in 2024 alleging that Mayweather had defaulted on nearly $4 million for luxury watches and diamond jewelry purchased in 2021.
The case, still unfolding, further illustrates the financial entanglements celebrities can face. The jeweler’s suit is centered on allegations of non‑payment for premium, high‑value items.
Such disputes not only tarnish reputations but also serve as cautionary tales for both businesses and investors to ensure contractual obligations are met.
Mayweather Real Estate and Tax Scams
While the majority of attention has been on crypto and sports endorsements, Floyd Mayweather’s ventures have also brushed up against real estate controversies.
One such case involves a high‑profile incident where Mayweather uncovered discrepancies in a property tax assessment during a real estate deal.
Here’s what went down:
In an attempt to acquire a multi‑million dollar Bel‑Air megamansion, Mayweather’s due diligence uncovered what appeared to be a systematic error—or worse, a deliberate scam—in the property’s tax evaluations.
This incident not only raised suspicions about the legitimacy of the property’s valuation but also shined a light on the broader issue of real estate tax fraud, prompting calls for increased transparency in property assessments.
So, whether in real estate or crypto, thorough due diligence is essential. Always verify property assessments and legal documents before making large‑scale financial commitments.

Breaking Down the “Scam” Label: What Does It Really Mean?
The term “scam” is often over‑used and misunderstood. In the context of Floyd Mayweather’s post‑boxing financial endeavors, it’s important to distinguish between outright fraud, mismanagement, and cases of poor judgment in celebrity endorsements.
Clarifying the Terms:
- Fraud: In legal terms, fraud involves intentional deception for financial gain.
- Misrepresentation: Sometimes celebrities may inadvertently misrepresent products due to a lack of due diligence.
- Risky Endorsements: Endorsing unproven or volatile financial products can be seen as reckless—even if not intentionally deceptive.
The Fine Line for Celebrities
For a celebrity like Mayweather, whose endorsements carry vast influence, disclosure is critical. Regulatory bodies like the SEC insist on full disclosure to protect consumers.
Even if an endorsement is not fraudulent by intent, failure to communicate relevant risks may lead to legal repercussions.
More so, The public must be aware of these nuances and not simply assume that the involvement of a celebrity guarantees reliability or success.
Quick Tip: If a celebrity is promoting a financial product, look for disclosures regarding payment or compensation. Don’t rely solely on an endorsement.

In the wake of several high‑profile cases, regulators are increasingly scrutinizing celebrity endorsements. This has led to stricter guidelines on disclosure and transparency.
