Recently, the Financial Times dropped the first bombshell, and The Block quickly added fuel to the fire.

The story itself is not complicated: a German-listed company controlled by Tether sold its bitcoin mining business, valued at about $200 million.

Who was the buyer? A review of regulatory filings showed it was several companies controlled by entities linked to Tether’s co-founder and CEO.

Moving assets from one hand to the other is hardly new.

But the details this time amount to a kind of art. In crypto, Tether is the real “shadow central bank.”

Its USDT stablecoin underpins settlement for much of the crypto market’s spot and derivatives trading. Almost every crypto trader has at least a few USDT sitting in their wallet.

And two of the company’s key figures, co-founder Giancarlo Devasini and CEO Paolo Ardoino, have just completed an almost silent transfer of wealth.

You would see none of it in the listed company’s announcements. The picture only starts to emerge when reporters dig through corporate registries in the British Virgin Islands and Canada.

One Deal, Three Layers of Nesting Dolls

In November 2025, German AI and data center company Northern Data announced that it would spin off and sell its bitcoin mining subsidiary, Peak Mining, for consideration capped at about $200 million.

Northern Data is listed on the Frankfurt and Munich stock exchanges. Tether is its largest single shareholder, and multiple media outlets have reported that Tether and related parties together exercise effective control over the company.

The announcement said the mining divestment was meant to “focus on AI infrastructure” and make the company’s transition cleaner. It sounded reasonable, even “correct.”

The problem was the buyer. The Financial Times reviewed corporate registry records in the British Virgin Islands (BVI) and Canada and found that the three companies acquiring Peak Mining, Highland Group Mining Inc., Appalachian Energy LLC, and 2750418 Alberta ULC, were backed by none other than Devasini and Ardoino.

BVI records show that the directors of Highland Group are precisely those two men.

Canadian filings show that the oddly named Alberta company has Devasini as its sole director.

The third company, registered in Delaware, cannot currently be traced to its controller because local law allows such information to remain confidential, but it has been grouped into the same control network.

In other words: the seller was a listed company controlled by Tether, while the buyer was an offshore company privately controlled by Tether executives.

Yet in the markets where Northern Data is listed, the deal was not clearly labeled as a “related-party transaction.”

The Same Seller

But the price was moving lower. At first glance, the “up to $200 million” figure does not look small.

But the context makes it interesting.

In August 2025, Northern Data had announced a non-binding agreement to sell Peak Mining to a company called Elektron Energy for $235 million.

That deal ultimately fell through. Who owned Elektron Energy? Market analysts, based on executive backgrounds, have “speculated” that it was also Devasini, but the control relationship between Elektron Energy and Devasini has not been confirmed by official filings.

In other words: the potential deal in August carried a higher valuation; the deal completed in November capped the consideration at $200 million.

The structure of that $200 million is also worth examining: only $50 million was paid upfront in cash, while the remaining “up to $150 million” was deferred consideration tied to a profit-sharing agreement for a mining site in Texas over more than three future years.

Put plainly, only $50 million was certain. How much of the remaining $150 million would actually be paid depends on operating performance. And who controls the operator?

The buyer itself. Independent research firm Edison Group was more direct: based on Peak Mining’s operating capacity, the deal valued each EH/s, the standard unit for mining computing power, well below the market range for comparable assets. A fire-sale price.

After the deal-related news was disclosed, Northern Data’s share price fell sharply, dropping nearly 13% in a single day. The market had already delivered its preliminary verdict.

How Could This Happen “Quietly”?

This is where a concept unfamiliar to many people comes in: Germany’s “Freiverkehr” market.

Northern Data is listed on the Munich Stock Exchange’s “Regulated Unofficial Market.”

The key point is that its disclosure requirements are far lighter than those of the main board.

Germany’s financial regulator, BaFin, imposes strict related-party transaction disclosure rules on main-board listed companies, but the Freiverkehr is governed by exchange self-regulation and does not require companies to disclose the buyer’s ultimate beneficial owner or whether a transaction is related-party in an asset-sale announcement.

Northern Data’s announcement only named the buyers, the three companies. It did not say who owned them.

Under the rules, it did not have to. This was not a loophole in the law.

It was a gray zone left by the rules themselves. Then look at where the buyer companies were registered: the British Virgin Islands, Alberta in Canada, and Delaware in the United States, all well-known “confidentiality-friendly” jurisdictions.

An offshore structure paired with a regulatory lowland made for an effective combination: the deal was completed, and only afterward did the market gradually learn who the buyers really were.

The Puzzle Is Not Finished: A Bigger Game

The spin-off of Peak Mining was not an isolated event.

Just days after Northern Data announced the sale of Peak Mining, on November 10, 2025, Nasdaq-listed conservative video platform Rumble announced that it would acquire Northern Data for about $767 million.

The deal would be done through a stock swap, with each Northern Data share exchanged for about 2.03 shares of Rumble Class A common stock.

After the transaction closes, former Northern Data shareholders, including Tether, are expected to hold about 30% of the combined company. So the full chain of interests looks like this: Tether owns more than 54% of Northern Data.

Northern Data sold its mining business at a “fire-sale price” to companies privately controlled by Tether executives.

Immediately afterward, Rumble agreed to acquire Northern Data, with former shareholders, including Tether, set to own about 30% of the combined company.

Northern Data previously owed Tether a 610 million euro shareholder loan. After the acquisition closes, half of that debt will be converted into Rumble shares at $7.88 per share, while the other half will become a secured loan from Tether to Rumble.

Tether has also signed a $100 million advertising agreement and a $150 million GPU computing power purchase agreement with Rumble.

In simple terms: during the divestment, the valuable mining assets moved into executives’ private pockets; the remaining “cleaner, easier-to-sell” AI assets were packaged into a U.S.-listed company structure and wrapped in a higher-valuation narrative.

If this looks familiar, it should. It resembles many capital-market restructurings built around “subtract first, multiply later.”

The difference is that this time the player is the world’s largest stablecoin issuer, whose product supports tens of billions of dollars in transactions every day.

Several Clouds That Have Not Cleared

This maneuver is not without costs.

The first cloud: the shadow of a tax investigation.

In September 2025, the European Public Prosecutor’s Office (EPPO), together with German and Swedish police, raided Northern Data’s offices. The core allegation is that Northern Data engaged in large-scale VAT fraud when importing about 10,000 Nvidia H100 GPUs, with media estimates putting the potential losses at more than 100 million euros.

Under Sweden’s tax incentives, equipment used for AI computing can receive VAT relief, but equipment used for cryptocurrency mining cannot.

Prosecutors suspect Northern Data misrepresented the purpose of those GPUs. Northern Data has denied the allegations, calling the matter a “misunderstanding of tax treatment.” But the investigation is still ongoing.

The second cloud: Tether’s own stability problem.

S&P Global Ratings recently downgraded its stability assessment of USDT to the weakest score of 5, citing the possibility that Tether’s bitcoin exposure may exceed its reserve buffer. If crypto markets swing sharply before the Rumble acquisition closes, the entire merger could be affected.

The third cloud: the old problem of audit transparency.

Tether has still never published a full independent audit report from one of the “Big Four” accounting firms. It has only released regular quarterly reserve statements and review opinions signed by third parties. For years, the market has viewed this as a key transparency weakness. Sixth, one telling detail: Tether CEO Paolo Ardoino recently warned publicly that a huge bubble is forming in AI, which could become one of the external risks facing bitcoin in 2026.

At the same time, through Northern Data and Rumble, Tether is effectively making a two-way hedge: on one side, 22,000 Nvidia GPUs and more than 600 MW of power capacity, putting it at the front of the AI computing power arms race; on the other, the privatization of Peak Mining keeps mining assets firmly in the founding team’s hands, beyond the constraints of listed-company reporting cycles and share-price volatility.

Publicly, it warns of a bubble. Privately, it is placing chips.

That, in itself, is a position. From a legal perspective, the deal likely has no obvious fatal flaw.

That is how Germany’s Freiverkehr market works. That is how offshore company confidentiality works. If executives buy assets from a company they control and the shareholders’ meeting does not block it, the process can go through. But legal has never meant reasonable.

This is almost a complete tutorial in how to transfer complex assets in broad daylight.

The fact that the rules do not prohibit something does not mean there is no problem. For outside investors holding Northern Data’s 28% minority stake, this was a forced “optimization”: they watched the company’s core assets flow to private entities controlled by the controlling shareholder at a price below market averages.

For Tether users, it is a signal: the company’s founding team has absolute control over assets, no matter what form those assets take or which legal entity holds them.

As for who ultimately wins and who loses, that may only become clearer after the Rumble transaction closes and the EU tax investigation reaches a conclusion.

But one thing is already clear: in this “decentralized” world built on code and protocols, real power has always been centralized.

A blockchain may have no boss. But money, companies, and assets always do. The code is decentralized; the people deciding where the money goes are not.
