BitMart appointed Alvarez & Marsal as its financial adviser on Wednesday, its self-imposed Sept. 9 deadline for an update, but did not publish the restructuring and business resumption roadmap it said it was developing.

Alvarez & Marsal will work with BitMart’s legal advisers to evaluate the exchange’s assets, financial position, stakeholder issues and possible paths forward, according to Wednesday’s announcement. The review will also consider proposals from unidentified third parties, BitMart said on X.

BitMart said it will deploy a dedicated web portal within five working days to collect user feedback on its action plan and future direction. It said further updates on the feedback process and action plan would follow on a rolling basis over the next three weeks.

Echo Base, which organized an ad hoc committee of BitMart claimholders, called the appointment “the most encouraging step BitMart has taken since July.”

“What arrived was an advisor appointment and two new deadlines, with no reserve position, no asset inventory, no recovery estimate and no withdrawal timetable,” Roshan Dharia, CEO of Echo Base, told Cointelegraph.

BitMart has faced scrutiny over its financial position and handling of customer assets since its July 26 wind-down announcement, after users reported withdrawal delays. 

Neither BitMart nor Alvarez & Marsal responded to Cointelegraph’s requests for comment on this story.

Crypto often markets itself as an open ledger where everything can be checked—yet the industry’s history is also packed with missing identities, unresolved thefts, and disappearing funds. From Bitcoin’s origin myth to high-profile exchange collapses and personal stories tied to key loss, the biggest mysteries endure not because they’re unobservable, but because the answers remain incomplete.

A recent roundup highlights ten lingering questions that still lack definitive resolution—from “who” authored Bitcoin’s earliest work to “where” certain assets ultimately went. Even when investigators trace portions of movements, the full picture is often still out of reach.

Key takeaways

• Satoshi Nakamoto remains unidentified despite major investigative claims, including a prominent 2026 New York Times report naming Adam Back as a leading candidate.
• Early Bitcoin holdings are still partly unexplained, including the “Patoshi” miner theory and the unknown remainder of funds tied to Mt. Gox.
• FTX’s alleged post-bankruptcy theft was reported at roughly $415 million, yet the perpetrator’s identity is still not established in the public record.
• Several mysteries involve key access rather than lost chains: cases like James Howells show that Bitcoin can remain on-chain even when keys are unrecoverable.
• Some stories intertwine with criminal allegations, such as QuadrigaCX, OneCoin’s Ruja Ignatova, and the unresolved circumstances around Nikolai Mushegian’s death.

Bitcoin’s origin stories still don’t add up

The most famous mystery—who created Bitcoin—dates back more than 17 years. The Bitcoin white paper was published in 2008, the genesis block was mined in January 2009, and the figure associated with the “Satoshi Nakamoto” name appeared active in early development before vanishing from public view around 2010.

Over the years, investigators and writers have circulated numerous candidates, ranging from cryptographers to early developers. In April 2026, The New York Times published an investigation that put British cryptographer Adam Back forward as its leading candidate, citing similarities in writing, shared cryptographic interests, Back’s work on Hashcash (which is referenced in the Bitcoin white paper), and other circumstantial connections. Back has denied the allegation.

Other notable claims have included Peter Todd and Hal Finney among historical suspects, and Craig Wright as a self-proclaimed creator who was reportedly ruled by a UK court not to be Satoshi. There are also fringe theories, including online speculation tied to newly released Epstein files; however, the article notes there is no credible evidence supporting the claim that Jeffrey Epstein was Satoshi.

From “Patoshi” to Mt. Gox: missing coins and partial answers

Another early-epoch Bitcoin mystery focuses on who mined a large stash attributed to a single operator. In 2013, blockchain researcher Sergio Lerner reportedly discovered a pattern in how the earliest blocks were mined and linked it to a miner he later dubbed “Patoshi.” Lerner estimated the holder controlled about 1.1 million BTC across roughly 22,000 blocks, making the entity—if the theory is correct—one of the largest Bitcoin holders. The account remains unproven, but it is presented as one of the strongest analytical links connecting early mining behavior to the era’s most influential identity, whether or not that identity is actually Satoshi.

Mt. Gox’s collapse remains another unresolved case with real-world consequences. When the exchange failed in February 2014, it initially claimed around 850,000 BTC had disappeared. Later, Mt. Gox reportedly found about 200,000 BTC in wallets it previously believed were empty. What happened to the rest is still unclear.

Even after more than a decade, creditors have begun receiving some returns, but the “missing” portion hasn’t been completely accounted for. The article references investigative claims and allegations tied to hacking and laundering, including US prosecutors’ assertions that Russian nationals stole and laundered about 647,000 BTC. Yet the broader question—who took the coins, how and when it occurred end-to-end, and where all remaining funds ended up—remains unanswered in full.

Exchange collapses and “missing keys” shape modern crypto mysteries

Some mysteries are about crime; others are about custody and control. The QuadrigaCX story, for example, turned on the claim that founder Gerald Cotten died in December 2018 and left the exchange unable to access customer crypto because private keys were allegedly unrecoverable. A later investigation by the Ontario Securities Commission reportedly concluded that Cotten transferred millions of client funds to personal accounts and used client assets to cover trading losses and expenses.

That finding reframed the mystery from “lost keys at the bottom of a grave” to an account of internal misuse—though it still leaves room for questions about the exact mechanics of the transfers and what, if anything, could have been recovered earlier.

Similarly, the disappearance of large sums after the FTX bankruptcy filing continues to be discussed as an open question of responsibility. After FTX filed for bankruptcy, digital assets began leaving the company’s wallets. According to reporting cited in the piece, about $415 million in crypto was reported stolen. US authorities later seized hundreds of millions in assets linked to the case, and investigators have traced parts of the movements. However, the article emphasizes that the attacker’s identity has not been publicly resolved.

Personal disappearances and “forever on-chain” losses

Not every mystery involves purely technical puzzles. The FBI still lists Ruja Ignatova, founder of OneCoin, as a top fugitive. According to the article, the FBI says the scheme defrauded victims worldwide of more than $4 billion and offers a reward of up to $5 million for information leading to arrest and conviction. Ignatova disappeared after traveling in October 2017, was added to the FBI’s Ten Most Wanted list in 2022, and the FBI maintains she remains at large, describing her as “well-funded” and “well-connected” in a later update.

Other cases show how crypto can make mistakes permanent in a different way. Welsh IT worker James Howells is tied to a long-running attempt to recover a hard drive containing Bitcoin keys. The article says Howells insists the drive ended up in a landfill and that he pursued excavation plans for years, though a High Court judge ruled in January 2025 that he had no realistic prospect of succeeding. The Bitcoin itself, importantly, is still present on the blockchain—accessible only if the keys can be found—illustrating a central tension in self-custody: the ledger may be transparent, but the ability to spend depends on the private keys.

In the DeFi era, the DAO hack from 2016 also remains unresolved. The article describes how an attacker exploited a vulnerability in The DAO’s smart contract to siphon more than 3.6 million ETH into a child DAO before the attack stopped. The attacker was never identified. A later claim by Laura Shin connected the attacker to Austrian programmer Toby Hoenisch, but he denied it and reportedly was never charged. The event reshaped Ethereum’s development and helped set the stage for Ethereum Classic, underscoring how disputes about immutability and governance remain practical—not just philosophical.

Finally, the piece includes a mystery tied to the death of early MakerDAO developer and Balancer co-founder Nikolai Mushegian. He was found dead off Condado Beach in Puerto Rico in October 2022, and local police said strong currents were responsible. But the article highlights that Mushegian had posted alarming messages on Twitter shortly before his death, warning of a possible assassination and alleging involvement by intelligence agencies and others. The Puerto Rico Justice Department reportedly investigated for almost a year and determined no criminal involvement. Still, his online warnings leave unanswered questions about what happened in his final hours.

When funds move to “burn” addresses, the trail can still go cold

Some mysteries are deliberately designed to end the path to recovery. In May 2026, the article says someone sent 107 BTC (reported as worth about $8.5 million at the time referenced) to a Bitcoin address from which the coins were rendered unspendable—effectively destroying them. It also notes that the coins had been acquired around 2014 when Bitcoin traded below $600, making the timing especially unusual given later price appreciation.

The article adds a further complication: one of five wallets reportedly sent about 20 BTC—around $1 million—to what appeared to be a large crypto custodian in March, with roughly the same amount returning three weeks later before the 107 BTC were ultimately burned. The sequence suggests interaction between multiple entities, but without a verified explanation, the motive remains speculative.

For readers, the common thread is that crypto’s transparency doesn’t automatically produce certainty: transactions are visible, but identities, intent, and final custody often remain obscure. The next developments to watch are the cases where authorities, auditors, or on-chain investigators can connect partial traces into complete narratives—especially for large losses where public reporting ends before accountability does.

Strategy, the largest corporate holder of Bitcoin, did not add to its BTC treasury this week. Instead, the company used part of its capital to repurchase $176.3 million worth of its preferred STRC stock, according to a filing with the U.S. Securities and Exchange Commission.

At the same time, Strategy said it has expanded a separate Digital Credit Securities repurchase program to a total of $2 billion—an adjustment that signals continued emphasis on capital management even as its Bitcoin buying pauses.

Key takeaways

• Strategy repurchased 1.8 million shares of STRC preferred stock for $176.3 million between Aug. 31 and Sept. 7, per an SEC Form 8-K.
• During the same period, Strategy reported no new Bitcoin purchases; its treasury remains at 845,050 BTC purchased for $63.6 billion at an average cost of $75,412 per BTC.
• The company doubled its Digital Credit Securities Repurchase Program to $2 billion.
• STRC trades below its $100 par value, which can affect Strategy’s ability to raise capital via STRC sales—potentially influencing dividend pressure.
• While Strategy paused buys, other corporate treasuries—such as Strive and Capital B—announced sizable Bitcoin acquisitions.

Strategy pauses BTC buying and turns to STRC repurchases

In an SEC filing released Tuesday, Strategy disclosed that it repurchased its STRC preferred shares instead of conducting fresh Bitcoin spot purchases. The company said it bought back 1.8 million STRC shares for an aggregate of $176.3 million over the period from Aug. 31 through Sept. 7.

Strategy’s Bitcoin treasury currently totals 845,050 BTC, acquired for $63.6 billion and reported at an average purchase price of $75,412 per BTC. The absence of new BTC purchases marks a shift from the prior activity noted in earlier reporting: Cointelegraph previously described Strategy’s first Bitcoin acquisition since mid-June, including a $370 million purchase.

For investors tracking corporate Bitcoin strategies, this kind of “pause with repurchase” dynamic matters because it reflects how management balances three competing needs: maintaining BTC exposure, supporting dividend obligations, and managing liquidity. When acquisitions slow, the spotlight often moves to how the company funds distributions and whether it can keep financing its treasury through preferred-share structures.

Why STRC’s discount could tighten funding options

Alongside the repurchase details, market pricing provides additional context for Strategy’s capital approach. The STRC preferred stock was trading around $97.70 in premarket activity on Tuesday, the report notes—about a 2.3% discount to its intended $100 par value. In contrast, Strategy’s Nasdaq-listed MSTR common stock was down more than 3% at last look, according to Yahoo Finance.

STRC is one of the main instruments Strategy uses to raise funds that ultimately support its Bitcoin accumulation. Because the preferred shares trade below par value, selling them may not generate as much capital per share as Strategy would receive if the shares traded at or above par. That pricing dynamic can constrain the company’s ability to raise incremental liquidity through STRC issuance and may increase pressure to maintain—or potentially raise—dividend rates through other means.

Strategy previously laid out a capital framework intended to preserve Bitcoin exposure while allowing Bitcoin sales to fund dividends. In June 29 coverage, Cointelegraph reported that Strategy unveiled this “capital framework” and increased the annual dividend rate on its STRC preferred stock to 12%. The current repurchase activity, combined with the reported discount to par, highlights the balancing act between funding dividends and maintaining the BTC treasury.

Digital Credit Securities repurchase program expands to $2 billion

Beyond STRC, Strategy also updated its capital return strategy. The company said it doubled the size of its Digital Credit Securities Repurchase Program to $2 billion.

While Bitcoin buying and preferred-share repurchases are typically the headline items for Strategy, programmatic repurchases of other securities can influence how much cash remains available for acquisitions, how debt or credit exposure is managed, and how quickly the company can respond to market conditions. For shareholders, these repurchase programs are often viewed as part of a broader approach: keeping capital flexible enough to act when Bitcoin buying opportunities align with financing and dividend needs.

Other corporate treasuries keep adding BTC

Strategy’s pause in new Bitcoin purchases came as other public corporate buyers continued accumulating. The contrast underscores a key feature of the corporate BTC landscape: even when one major player slows down, the broader sector may still be active.

According to CEO Matt Cole, Strive—described in the report as the fifth-largest corporate Bitcoin treasury—acquired 1,375 BTC for $109 million. That purchase brought Strive’s total holdings to 24,531 BTC, with an average cost of $79,281 per BTC. Cole shared the information via X on Monday, as referenced by the report.

France-listed Bitcoin treasury Capital B also revealed a new purchase. The report states that Capital B bought $25 million worth of Bitcoin on Monday—its largest acquisition in nearly a year—lifting its holdings and helping it move ahead of H100 Group among publicly traded BTC holders, based on the framing of the original coverage.

For traders and long-term holders, these parallel moves matter for sentiment and for measuring how concentrated corporate demand may be. If Strategy momentarily steps back, investors may look to competitors for confirmation that institutional-style Bitcoin buying remains steady across the category.

What to watch next is whether Strategy resumes BTC acquisitions after this repurchase-focused week, and how the discount-to-par behavior of STRC influences future funding capacity and dividend decisions—especially if market pricing makes STRC issuance less effective.
