US DOJ Charges Two Russians With Mt. Gox Hack

Upbit, South Korea’s largest cryptocurrency exchange operated by Dunamu, announced on Jan. 2 that its user base surpassed 13 million by the end of last year. With South Korea’s population at 51.6 million, the data implies that roughly one in four Koreans now holds an account on the platform. Demographic breakdowns show that users in their 30s comprise the largest cohort at 28.7%, followed by those in their 40s at 24.1% and 20s at 23.2%. Users in their 50s accounted for 16.9%, while those in their 60s and 70s made up 6.0% and 1.1%, respectively. Adoption is particularly high among younger generations, with the combined total of users in their 20s and 30s reaching 5.48 million. Based on Ministry of the Interior and Safety data showing 12.37 million people aged 20 to 39 as of November, approximately 44% of Koreans in this age demographic use the platform. Upbit added 1.1 million new users last year, with men comprising 56.9% of new accounts and women 43.1%.Photo by Kanchanara on UnsplashXRP overtakes BTC and ETH in tradingIn terms of trading volume, Ripple’s XRP was the most traded cryptocurrency in 2025, outpacing both Bitcoin and Ethereum. Daily activity peaked in the morning, coinciding with the start of the typical business day. The highest volumes were recorded at 00:00 UTC, or 9 a.m. Korea Standard Time. Beyond standard trading, users are increasingly turning to Upbit’s asset management tools. Since its 2022 launch, the platform’s staking feature has attracted over 300,000 users, generating 257.3 billion won ($178.6 million) in total rewards. Furthermore, a dollar-cost averaging feature introduced in August 2024 has drawn about 220,000 users, with cumulative investments totaling 478.1 billion won ($331.9 million). Kbank eyes public listingIn the broader ecosystem, Upbit’s banking partner is preparing for an initial public offering (IPO) this year. Kbank, an internet-only lender that has partnered with Upbit since 2020, is closely linked to the exchange through shared customers. According to Hansbiz, crypto-related funds accounted for roughly 16% of Kbank’s total deposits as of the first half of 2025. Under South Korean law, fiat-to-crypto service providers must secure real-name accounts from a local bank, meaning Upbit users are required to deposit Korean won at Kbank before trading on the exchange. However, Kbank’s financial performance has softened following the 2024 implementation of the Virtual Asset User Protection Act, which compelled the bank to raise annual interest rates on deposits from Upbit users from 0.1% to 2.1%. On a consolidated basis, net interest income totaled 323.2 billion won ($224 million) in the third quarter of 2025, down 13% year over year. Net fee income remained in the red, posting a loss of 2.8 billion won ($1.94 million), widening from a 1.3 billion won loss in the same period a year earlier. This latest IPO push follows two failed attempts and carries contractual implications. When Kbank raised 725 billion won ($503 million) in 2021 from investors including Bain Capital and MBK Partners, it pledged to list its shares by July 2026. If the upcoming attempt fails, those backers could exercise drag-along rights and put options, potentially resulting in increased financial obligations for Kbank. Meanwhile, Upbit has seen other notable shifts in its business and governance. In November, Dunamu and Naver Financial, a subsidiary of internet giant Naver, approved a merger plan structured as a comprehensive share swap at a ratio of 1 to 2.54. At the time of the announcement, market observers estimated Dunamu’s valuation at 15 trillion won ($10.4 billion), compared with 5 trillion won ($3.5 billion) for Naver Financial. 

North Korean Hackers Take Off With $100M Atomic Wallet HoneypotHaving reported last week on a $35 million hack of Atomic Wallet users’ funds, an update on the matter reveals that the situation is much worse than originally thought, with losses now exceeding $100 million.Photo by Kenny Eliason on Unsplash5,500 wallets compromisedThe attack has sent shockwaves throughout the crypto community, raising concerns about the security of decentralized wallets. Atomic Wallet, an Estonia-based project known for its non-custodial approach where users take full responsibility for storing their assets securely, has been hit hard by this unforeseen breach.Elliptic, a crypto compliance analysis company, published an update on the situation on Tuesday. According to that blog article, it estimates that approximately 5,500 crypto wallets have been compromised, meaning that losses have risen to more than $100 million, highlighting the severity of the attack.Despite the significant impact on users, Atomic Wallet has yet to provide an explanation regarding the root cause of these substantial losses. Users have taken to social media in frustration, demanding clarification from the company. Surprisingly, the company’s last direct update on Twitter dates back to June 7, leaving users feeling even more anxious.User frustrationOne user, Ezra Carlson, expressed frustration, questioning why Atomic Wallet didn’t warn users when they were aware of the ongoing hack. Carlson tweeted: “@AtomicWallet why won’t AM give me a straight answer about why they didn’t warn me, knowing full well that they were being hacked, that it was not safe to use AM last week before I made a transfer to my wallet that was then hacked.”Another user, “Real Deal Crypto,” criticized Atomic Wallet’s lack of updates, stating: “Your last update was five days ago — SERIOUSLY?!?!”Although Atomic Wallet acknowledged reports of compromised wallets on June 3, downplaying the impact by claiming that less than 1% of users were affected, the staggering sum of losses indicates a significant breach. Its last communication on the matter came on June 11 when, in responding to a user, the firm said that it continued to investigate and to await Twitter updates on the matter.Hack tied to North Korea’s Lazarus GroupElliptic has connected this heist to the notorious Lazarus Group, a cyber-criminal organization with ties to the North Korean regime, responsible for stealing over $2 billion in crypto assets through various thefts. This attribution marks the first time a significant crypto heist has been openly linked to the Lazarus Group since their $100 million exploit of Horizon Bridge in June 2022.In response to the heist, Elliptic has been collaborating with international investigators and exchanges, mobilizing resources to recover the stolen assets. Their efforts have reportedly led to the freezing of over $1 million worth of funds. However, the thief has adapted its behavior in response to the freezing of assets, turning to the Russia-based Garantex exchange to launder the stolen assets, as noted by Elliptic.This recent attack adds to a series of notable breaches in the crypto industry. Jimbos Protocol experienced an exploit resulting in a loss of $7.5 million, and Tornado Cash faced a malicious proposal that seized control of its governance in May. According to a report by Chainalysis, crypto hackers made off with an estimated $3.8 billion in 2022, with North Korea being responsible for a significant portion of the attacks.

Beijing-headquartered crypto mining equipment manufacturer Canaan recently revealed its financial results for the fourth quarter of 2023, demonstrating that it continues to struggle with profitability despite positive numbers relative to revenues and growth.Photo by Sasun Bughdaryan on UnsplashIncreased revenues and salesAccording to the company’s filing, during the last quarter of 2023 Canaan reported a surge of 45.7% in total computing power sold compared to the preceding quarter, reaching 5.5 million Thash/s. This ascent, which reflects a 191.9% increase from the same period in 2022, signifies not just a recovery but a robust resurgence in demand and operational ability. The company's dispatch of 19.6 million Thash/s throughout the year, marking a 29.6% leap from 2022, aligns with the rebound in bitcoin prices observed in Q4 2023, a pivotal factor shaping Canaan's operational revitalization. 47% growth on previous quarterA closer examination of the financials reveals not only surpassing total revenues but also a notable 47.3% quarter-over-quarter growth. Canaan's foray into international markets, bolstered by securing substantial orders from esteemed public company clients, underscores a buoyant sales performance and a positive outlook for the computing sector. Despite the buoyant sales and revenue figures particularly in the mining machine market, the sector has faced ongoing regulatory uncertainties and market fluctuations. Nonetheless, the company's strategic initiatives, alongside the positive market effects of the approval and listing of spot bitcoin exchange-traded funds (ETFs), have been positive. Moreover, Canaan's investments in wafer supply capabilities and strategic financial maneuvers garnered approximately US$136 million through at-the-market (ATM) programs and preferred shares. Recording a lossYet, the company’s journey in 2023 was not without its hurdles. Q4 2023 witnessed a significant increase in product revenues from the previous quarter but a decline from Q4 2022, attributed to dwindling sales prices as the halving event loomed, underscoring the volatility inherent in the cryptocurrency market. Results published last year are indicative of the company’s difficulty. In Q2 2023, revenues were strong, yet the company wasn’t turning a profit.With Q4 results, it’s now clear that the firm lost $421 million in 2023. In Q4, Canaan recorded a net loss of $139 million. That compares with a loss of $91 million in Q4, 2022. The company also expects tough market conditions in 2024. In its forward-looking outlook, it stated:”For the first quarter of 2024, and the second quarter of 2024, the Company expects total revenues to be approximately US$33 million and US$70 million, respectively, considering the challenging market conditions across the industry. This forecast reflects the Company’s current and preliminary views on the market and operational conditions, which are subject to change.” The crypto mining sector remains a very challenging market. With the upcoming Bitcoin halving event set to occur in April, it’s expected that as much as 20% of mining capacity could be forced offline, as some equipment would simply fail to mine on a profitable basis. Indicative of the challenges within the sector, crypto miner Core Scientific was forced into bankruptcy due to market difficulties in December 2022. It has only recently exited that bankruptcy process and now expects to generate revenues of $600 million in 2024. Another Bitcoin miner, Riot Platforms, has warned that profitability may be difficult to achieve in 2024 due to chip shortages.
