As bitcoin hovered around $238 in early September 2015, the cryptocurrency was making headlines for reasons far removed from its intended purpose as a peer-to-peer electronic cash system. From the final liquidation of Silk Road assets by the US government to a wave of bitcoin-fueled extortion tied to the Ashley Madison data breach, the first week of September laid bare the dual-use nature of the world’s first cryptocurrency.
TL;DR
- The US Marshals Service confirmed a final auction of 44,336 BTC seized from Silk Road founder Ross Ulbricht
- Cloudmark research identified 67 suspicious bitcoin transactions totaling 70.35 BTC linked to Ashley Madison blackmail
- Blockchain.info, the world’s most popular bitcoin wallet, experienced a major outage on September 4
- The seized Silk Road bitcoins were worth approximately $122 million at the time of seizure in late 2013
- Ethereum, launched just weeks prior, traded at just $1.21
The Final Silk Road Bitcoin Auction
The US Marshals Service announced it would hold one final auction to sell off the remaining bitcoins confiscated from convicted Silk Road operator Ross Ulbricht before the end of 2015. In total, the government seized more than 144,000 BTC from Ulbricht in late 2013, along with an additional 29,655 BTC recovered from wallets on the darknet marketplace at the time of its shutdown.
The final auction would offer 44,336 BTC, valued at approximately $10 million at September 2015 prices. This represented the last chapter of what had been a series of high-profile government bitcoin sales. The most recent auction, held in March 2015, attracted 14 registered bidders competing for 50,000 BTC worth roughly $13.4 million. The secretive bitcoin firm Cumberland Mining walked away with the lion’s share, purchasing 47,000 BTC in that sale alone.
A spokesperson for the USMS confirmed to CoinDesk: “We still don’t have any dates to announce, but do expect to hold the event before the end of the year.” The auction process itself was notable for bringing institutional interest into the bitcoin market, with qualified bidders required to meet strict regulatory requirements.
Ashley Madison Blackmailers Exploit Bitcoin’s Pseudonymity
While the US government was auctioning seized bitcoins through official channels, cybercriminals were exploiting bitcoin’s pseudonymous nature for far more nefarious purposes. Network security firm Cloudmark published research on September 1st revealing the financial scale of blackmail operations targeting users of the hacked infidelity website Ashley Madison.
Cloudmark’s software engineer and research analyst Toshiro Nishimura traced 67 suspicious bitcoin transactions totaling 70.35 BTC, worth approximately $15,814 at the time, within a four-day extortion window. The blackmailers demanded 1.05 BTC per victim, and Cloudmark identified payment addresses that showed little to no transaction history before the blackmail campaign began.
“We conservatively restricted ourselves to ordinary transactions with two or less outputs, thus excluding those which were less likely to be simple one-to-one payments,” Nishimura wrote in the analysis. The researcher noted that the total extracted could be as high as $6,400 from individual victims, though the actual figure was likely higher given the conservative methodology used.
The Ashley Madison breach demonstrated both the utility and the danger of bitcoin in extortion schemes. The cryptocurrency’s global reach, irreversible transactions, and relative anonymity made it the ideal payment mechanism for criminals seeking to monetize stolen personal data.
Blockchain.info Wallet Goes Dark
Adding to the turbulence, Blockchain.info, operator of the world’s most popular bitcoin wallet service, went offline on September 4th. The outage was first noticed around 05:44 UTC, with Reddit users reporting the issue shortly after 07:00. The site’s homepage displayed a maintenance message: “We will be back shortly. Blockchain.info is currently down for maintenance.”
Blockchain co-founder Nic Cary attributed the downtime to the company “installing some new equipment,” noting that the company had been “growing fast” lately. The outage followed a separate six-hour downtime experienced by global bitcoin marketplace LocalBitcoins earlier that same week, which the platform’s community manager blamed on aging server infrastructure.
The back-to-back outages underscored the fragility of early bitcoin infrastructure, where even the most established service providers struggled to maintain uptime during periods of rapid growth.
A Market in Transition
The events of early September 2015 painted a complex picture of a cryptocurrency ecosystem in rapid transition. Bitcoin’s market capitalization stood at approximately $3.5 billion, with BTC trading at $238. Ethereum, which had launched its Frontier network just six weeks earlier on July 30th, was still finding its footing at $1.21 with a modest market cap of $88 million. The total crypto market was a fraction of what it would become, dominated overwhelmingly by bitcoin itself.
The juxtaposition of government auctions, criminal extortion, and infrastructure failures highlighted the multifaceted challenges facing the young cryptocurrency industry. Each challenge also represented an opportunity — driving improvements in blockchain analysis, security practices, and service reliability that would prove essential as the market grew by orders of magnitude in the years ahead.
Why This Matters
The events of September 2015 represented a microcosm of bitcoin’s broader identity crisis. Was it a tool for financial freedom, a magnet for criminal activity, or a speculative asset class being legitimized through government auctions? The answer was all of the above. The Silk Road auctions established an important precedent for government handling of seized digital assets, while the Ashley Madison blackmail demonstrated how quickly bitcoin could be weaponized by bad actors. Meanwhile, the infrastructure outages served as a wake-up call about the reliability of centralized services built on top of a decentralized protocol. These themes — regulation, crime, and infrastructure resilience — would continue to define the cryptocurrency narrative for years to come.
