North Korean hackers linked to hack of 4,500 bitcoins from Japanese crypto exchange – SiliconANGLE
North Korean hackers linked to the infamous Lazarus hacking group have been identified as being behind the theft of more than 4,500 bitcoins from Japanese cryptocurrency exchange DMM Bitcoin earlier this year.
The Federal Bureau of Investigation, in conjunction with the Department of Defense Cyber Crime Center and National Police Agency of Japan, has revealed that hackers who go by the name of TraderTraitor, an arm of Lazarus, successfully stole the equivalent of $308 million from DMM in May and have detailed how the North Korean hackers did so.
The investigation into the hack found that in late March 2024, a North Korean cyber actor pretending to be a recruiter on LinkedIn contacted an employee at Ginco, a Japanese enterprise cryptocurrency wallet software company. The threat actor sent the target, who maintained access to Ginco’s wallet management system, a URL linked to a malicious Python script under the guise of a pre-employment test located on a GitHub page. The victim copied the Python code to their personal GitHub page and was subsequently compromised.
With the access gained, the TraderTraitor hackers sat patiently, waiting until May to exploit their access. To steal the bitcoin, the actors exploited session cookie information to impersonate the compromised employee and successfully gained access to Ginco’s unencrypted communications system. With this access, it’s believed that the hackers then manipulated a legitimate transaction request from a DMM employee, resulting in the theft of 4,502.9 bitcoin.
The stolen bitcoin was subsequently transferred to TraderTraitor-controlled wallets, which ultimately lead back to the North Korean government.
“The FBI, National Police Agency of Japan and other U.S. government and international partners will continue to expose and combat North Korea’s use of illicit activities — including cybercrime and cryptocurrency theft — to generate revenue for the regime,” the FBI noted in a statement.
The involvement of both North Korea and an arm of Lazarus in the hack comes as no surprise, as the hack of DMM isn’t the first time Lazarus has targeted cryptocurrency exchanges.
In 2022, Lazarus was linked to the hack on the Ronin Network that led to the theft of $615 million in cryptocurrency, and more recently, in July, the group was linked to the theft of $234.9 million in cryptocurrency from India-based cryptocurrency exchange WazirX.

What Is Risk Management in Crypto Trading? A 2026 Guide
If you’re wondering how to manage risk when trading crypto, remember that this market shifts rapidly; pairing enthusiasm with prudence is the wiser approach to digital assets. In practice, risk management is the process of identifying what could go wrong in a trade, deciding in advance how much you can lose, and using tools (like position limits and exits) to keep any single mistake or market move from doing outsized damage.
Summary
Crypto and traditional securities expose investors to different kinds of risk, and treating them as identical leads to poor assumptions. Because these markets operate on distinct mechanics, each must be assessed within its own context. Risk management matters because the same volatility and structural quirks that create opportunity can also turn a small misstep into a large loss, and protecting capital is what keeps you in the game long enough to learn and improve.
In fast-moving crypto markets, a structured risk plan turns uncertainty into defined decisions you can execute consistently.
Speculative Securities: A Quick Primer
When an instrument is considered speculative, there is a real chance of losing interest, principal, or both. Understandably, many shy away from such exposure, yet outcomes are unpredictable and can result in either significant gains or losses.
Consider high-yield bonds — commonly known as junk bonds. Issuers often have low credit ratings, so defaults are more likely than with investment-grade borrowers. In the late 1980s, these bonds were labeled speculative-grade or below-investment-grade. Many issuers were in or near bankruptcy, and it was uncertain which companies would survive. Backing a firm that emerged successfully could yield outsized returns, but many investors saw capital evaporate. Even after fundamental analysis — examining company history, financials, performance data, and market trends — the uncertainty kept these assets firmly speculative.
Crypto’s Shifting Risk Profile
Cryptocurrency markets are also speculative, and the payoff potential can be dramatic; for instance, Bitcoin climbed from $10,000 to $20,000 within two weeks in December 2017. As with junk bonds in their heyday, no one can say which networks or tokens will lead over the long term. The risk drivers, however, are not the same as those in high-yield debt, and having a framework to manage exposure still matters. Key categories often include market risk (rapid price swings), liquidity risk (thin order books and slippage), operational and technology risk (platform outages and smart-contract bugs), regulatory risk (policy shifts), and custody or cybersecurity threats.
Much of crypto is new and evolves at breakneck speed. Classification remains unsettled: the Internal Revenue Service treats crypto as property subject to capital-gains tax, while the Securities and Exchange Commission views certain assets as securities that fall under its oversight. When fundamental definitions remain fluid, it’s easy to brand the space as risky — which is why approaching it with care and curiosity is sensible.
Speculative Risk-Taking Requires Deliberate Choices
Investing blends art and science, and even experienced professionals encounter surprises in the crypto market. What it should not become is a gamble. Do rigorous research, learn how the cryptocurrencies and platforms you use actually work, and understand the known hazards before you trade.
Strong risk habits tend to look similar across strategies: using stop-loss orders (or pre-defined exits) to cap downside, sizing positions so a single trade can’t meaningfully harm the account, diversifying so one token or theme doesn’t dominate outcomes, setting a risk/reward ratio before entering, and trading only with risk capital you can afford to lose without disrupting your financial life.
A simple five-step process can help bring structure to your approach: identify risks, analyze how likely and severe they are, choose controls to address them, implement those controls consistently, and then monitor results and adjust as conditions change.
Your personal risk tolerance is not just a number. It reflects your financial situation (cash needs and debt), your goals and time horizon, your experience with drawdowns, and your psychological comfort with uncertainty. Practical ways to assess it include choosing a maximum acceptable percentage loss per trade and per day/week, paper trading to observe how you react under pressure, keeping a short trading journal, and stress-testing positions by imagining a sharp drop and deciding whether you could follow your plan without freezing or panic-selling.
You can also calculate risk parameters directly. A common approach is to set a maximum account risk per trade (for example, 1%) and then size the position from the distance between entry and stop. Position size (units) can be calculated as: (Account Size × Risk %) ÷ (Entry Price − Stop Price) for a long trade.
Example: If your account is $10,000 and you risk 1% ($100) on a trade, and you plan to buy at $50 with a stop at $48, your risk per coin is $2. Your position size would be $100 ÷ $2 = 50 coins. If your target is $56, the potential reward per coin is $6, so the risk/reward ratio is $6 ÷ $2 = 3:1.
Different risk decisions also fall into four broad types: avoiding risk (skipping a trade or asset you don’t understand), reducing risk (tightening sizing rules or using exits), transferring risk (using hedges or shifting exposure off a single venue), and accepting risk (taking a measured position because the potential upside justifies the predefined downside).
Common mistakes often show up when plans aren’t written down or enforced: overleveraging, trading without a stop, letting emotions override rules, building a portfolio that is effectively one crowded bet, and ignoring market-moving news or changes in exchange conditions that can affect execution.
Keep the following factors in mind as you invest and design a crypto risk management process:
Risk Type
Description
Price-Swing Risk
Digital assets can move sharply in short windows, and sudden drawdowns can trigger forced selling or emotional decisions if losses are not capped in advance.
Regulatory Uncertainty
Rule changes, enforcement actions, and unclear jurisdiction can affect access, listings, disclosures, and what participants can do on a given platform.
Cybersecurity and Custody Threats
Account takeovers, phishing, compromised devices, and wallet or key-management failures can lead to irreversible loss of funds.
Liquidity Constraints
Thin order books and fast markets can create slippage, making it difficult to enter or exit near intended prices, especially during stress.
Operational and Technology Risk
Outages, congestion, bugs, and smart-contract failures can interrupt trading, delay transfers, or change the behavior of on-chain products.
- Market Volatility
- Market Regulation
Perhaps the most important point when shaping an effective approach is to avoid forcing legacy finance labels onto a new asset class. While many still regard the space as speculative, there is growing agreement that the underlying technology, networks, and crypto assets have real value. Methods to define and measure that value are still developing, and they will ultimately inform how traders perceive risk in this market.

Bitcoin Difficulty Climbs 3.87% as Hashrate Slips and Next Cut Looms
Key Takeaways:
- Bitcoin difficulty rose 3.87% at block 943488 as hashrate fell 60.45 EH/s; a 15.73% cut is projected.
- Miners face $30.67 PH/s hashprice and 0.56% fees, pushing firms toward AI over BTC mining.
- Bitcoin network nears April 19, 2026, adjustment as slower 11:51 blocks signal easing difficulty ahead.
Bitcoin Mining Tightens
The Bitcoin network has logged a total of seven adjustments this year, comprising three increases and four decreases. The most recent reduction, two weeks ago, was sizable, arriving after consecutive gains of 14.73% and 0.45% across the prior two epochs.
Following the latest adjustment, the difficulty rating is now 3.87% higher, making blocks that much harder to discover, and it further stands at 138.97 trillion times more difficult than Bitcoin’s launch.
As of 4 p.m. Eastern time, 181 of the 2,016 blocks in the current epoch have been mined, placing the network roughly 9% of the way toward the next adjustment expected on April 19, 2026. While it remains early and conditions can shift considerably between now and then, current estimates point to a projected 14.27% reduction.
This outlook stems from a noticeable slowdown in block intervals over the past day, with data from hashrateindex.com indicating an average block time of 11 minutes 39 seconds, well above the expected 10-minute cadence.
What’s behind the shift? A decline in hashrate. Bitcoin.com News reported on March 28 that the Bitcoin network’s total computational power had exceeded 1,000 exahash per second (EH/s), or 1 zettahash per second (ZH/s). On that day, hashpower reached 1,022 EH/s, whereas it now sits 60.45 EH/s lower at 961.55 EH/s.
Revenue Compression Tightens the Squeeze
Compressed revenues are likely a key factor behind the downturn, alongside mining operations opting to allocate resources toward artificial intelligence (AI) infrastructure rather than mining BTC in pursuit of stronger returns. An infrastructure provider deploying its megawatts toward AI rather than mining bitcoin can realize significantly higher returns, a dynamic that has persuaded many of today’s operators to redirect their focus.
A daily hashprice of $30.67 per petahash per second (PH/s) ranks among the lowest revenue levels bitcoin miners have faced since the network’s early years, when bitcoin carried a far smaller valuation. With 106,335 blocks remaining until the next halving, conditions are poised to tighten further.

Adding pressure, miners cannot rely on fees, which account for just 0.56% of the block reward. In effect, the system appears to be approaching a breaking point. Yet Bitcoin’s difficulty adjustment is engineered for precisely this scenario. If miners exit and hashrate declines, difficulty adjusts downward, drawing participants back with more accessible conditions.

A Beginner’s Guide to Understanding Cryptocurrency Markets
Cryptocurrency has rapidly transformed from a niche concept into a global financial phenomenon. With increasing adoption, digital currencies are now being explored not only as investment assets but also as tools for innovation across industries. For beginners and experienced participants alike, understanding the broader cryptocurrency landscape is essential to making informed decisions.
What Makes Cryptocurrency Unique?
Unlike traditional financial systems, cryptocurrencies operate on decentralized networks powered by blockchain technology. This means there is no central authority controlling transactions. Instead, transactions are verified by a distributed network of participants, ensuring transparency and security.
This decentralization is one of the key reasons why cryptocurrencies have gained popularity. It allows individuals to have greater control over their assets and reduces reliance on traditional financial institutions.
The Expanding Crypto Ecosystem
Over the years, the cryptocurrency ecosystem has grown significantly. It now includes a wide range of applications such as decentralized finance (DeFi), non-fungible tokens (NFTs), and blockchain-based gaming.
Each of these sectors contributes to the overall development of the industry. DeFi platforms enable lending, borrowing, and trading without intermediaries, while NFTs redefine digital ownership. Together, these innovations highlight the versatility of blockchain technology.
Understanding Market Behavior
Cryptocurrency markets are known for their volatility. Prices can fluctuate rapidly due to various factors, including:
- Global economic conditions
- Regulatory announcements
- Technological advancements
- Market sentiment and speculation
This unpredictability can create both opportunities and risks. While some participants benefit from price movements, others may face losses if they are not adequately prepared.
The Importance of Long-Term Perspective
Many newcomers enter the crypto market with the expectation of quick profits. However, experienced participants often emphasize the importance of a long-term perspective. Instead of focusing solely on short-term price changes, it is beneficial to consider the underlying value and potential of a project.
A long-term approach allows individuals to better navigate market fluctuations and make decisions based on fundamentals rather than emotions.
Spotlight on Emerging Discussions
Within the broader cryptocurrency space, certain tokens and projects frequently become part of ongoing discussions. One such example is ankr crypto. Conversations around ankr crypto often reflect a growing interest in blockchain infrastructure and decentralized cloud solutions. As discussions around ankr crypto continue, they highlight how different projects are contributing to the evolution of the ecosystem in unique ways.
The Role of Technology in Crypto Growth
Technology plays a central role in the expansion of cryptocurrency. Innovations such as smart contracts, layer-2 scaling solutions, and interoperability protocols are helping to improve efficiency and usability.
These advancements address some of the key challenges faced by the industry, including high transaction fees and network congestion. As technology continues to evolve, it is likely to drive further adoption and open up new possibilities.
Risk Management and Strategy
Given the volatile nature of the market, having a clear strategy is essential. Some common approaches include:
- Diversifying investments across multiple assets
- Setting realistic expectations
- Avoiding impulsive decisions
- Staying updated with market developments
Risk management isn’t just about keeping losses from happening. It’s also about keeping participation fair and long-lasting.
Security and Awareness
Security is a critical aspect of engaging with cryptocurrencies. Since users have full control over their assets, they are also responsible for protecting them. This includes using secure wallets, enabling authentication measures, and being cautious of scams.
Awareness and education play a significant role in minimizing risks. By understanding common threats and best practices, individuals can safeguard their investments more effectively.
The Future of Cryptocurrency
The future of cryptocurrency is shaped by continuous innovation and increasing adoption. As more industries explore blockchain technology, the role of digital assets is likely to expand beyond finance.
However, challenges such as regulatory uncertainty and scalability remain. Addressing these issues will be crucial for the long-term success of the industry.
Despite these challenges, the overall trajectory of cryptocurrency remains promising. With ongoing development and growing interest, the ecosystem is expected to evolve in ways that could redefine how value is exchanged and managed.
Conclusion
Cryptocurrency represents a dynamic and rapidly evolving field that offers both opportunities and challenges. By understanding its fundamentals, staying informed about developments, and adopting a disciplined approach, individuals can navigate the market more effectively.
While trends and discussions may come and go, focusing on the broader principles of technology, utility, and risk management can provide a solid foundation. As the digital economy continues to grow, cryptocurrency is set to remain an important part of the financial landscape.
