The cryptocurrency market experienced significant turbulence in February 2025, marked by unprecedented security breaches, substantial market volatility, and notable policy shifts. Here's a comprehensive overview of the key events that shaped the crypto landscape this past month. Market Performance Bitcoin’s plunge below $80,000 marked one of its most volatile months in recent history. The primary trigger was the Bybit hack, which shattered investor confidence and led to a wave of sell-offs. Additionally, new tariffs announced by the U.S. exacerbated market fears, causing investors to flock to traditional assets. This sharp decline also raised questions about Bitcoin's status as a "digital gold" and its ability to act as a hedge against economic instability. Altcoins were not spared, with Ethereum, Solana, and Cardano witnessing double-digit declines. The synchronized drop highlights the interconnectedness of the crypto market and the prevailing investor sentiment that views altcoins as higher-risk assets compared to Bitcoin. Analysts argue that this event could accelerate institutional calls for clearer regulations to protect against such cascading effects. Security Concerns The Bybit breach, resulting in a $1.5 billion theft, is now the largest crypto exchange hack to date. The incident exposed significant vulnerabilities in exchange security practices, particularly in managing hot wallets and API keys. With the FBI attributing the attack to North Korea's Lazarus Group, geopolitical dimensions of crypto security are becoming increasingly evident. Read our coverage of the hack here The broader industry is now calling for more stringent self-regulation, possibly paving the way for an independent crypto security standards body. These responses indicate a growing recognition that security lapses could severely undermine mainstream adoption. Points of Interest Trump’s Crypto Reserve Former President Donald Trump's announcement of a U.S. cryptocurrency reserve is a landmark move - potentially aimed at countering China's influence through its digital yuan. By positioning a state-backed digital reserve, the U.S. may be seeking to secure its financial sovereignty in the evolving digital economy. Analysts speculate that this move could lead to a domino effect, prompting other nations to expedite their CBDC (Central Bank Digital Currency) projects. SEC Halts Investigations The SEC's suspension of crypto investigations surprised many, with insiders suggesting that this could signal an overhaul of existing regulatory frameworks. While some argue that this pause might allow for more constructive regulations, others fear it could embolden bad actors. The move has sparked debates about the balance between fostering innovation and ensuring investor protection. Looking Ahead The events of February 2025 underscore the crypto market's dual challenges: managing security risks and navigating regulatory uncertainties. Institutional investors are likely to advocate for a comprehensive regulatory framework that balances innovation with robust protections. As the U.S. contemplates a national crypto reserve, the strategic importance of digital currencies in geopolitics is becoming undeniable. The coming months could be pivotal in determining the direction of both market sentiment and regulatory policy.
What is the Bybit Hack? A Quick Primer
8 mins read
The recent $1.5 billion hack of cryptocurrency exchange Bybit has sent shockwaves through the crypto community. If confirmed, it would rank among the largest thefts in the industry's history, allegedly orchestrated by North Korean hackers. This breach raises urgent questions about the security of centralized exchanges (CEXs) and whether investors should continue entrusting them with their digital assets. As the investigation unfolds, it’s crucial to analyze how this attack happened, how it could have been prevented, and how individual investors can protect themselves from similar threats. While centralized exchanges offer convenience, this incident reinforces a growing truth: self-custody is the safest option for holding crypto assets. Timeline of the Bybit Hack 1. A Routine Cold Wallet Transfer Bybit initiated a multisig transfer from its cold wallet to a warm wallet, a standard operational process. Multisig means that multiple authorized signers (executives or security officers) must approve the transaction before it executes. 2. The Attack Was Already in Motion The attackers had possibly compromised every multisig signer’s device with malware. When the signers reviewed the transaction, the UI showed the correct wallet address and a legitimate transaction on the @safe platform (formerly Gnosis Safe, a popular multisig protocol). 3. A Hidden Transaction Manipulation Behind the scenes, the actual signing request was not for a transfer—it was a request to change the smart contract logic of the ETH cold wallet. Once all signers approved what they thought was a normal transfer, the hackers gained full control of the ETH cold wallet. 4. Complete Takeover and Theft With the contract permissions changed, the attackers drained all ETH from the cold wallet. The funds were transferred to an unidentified address, making recovery nearly impossible. 5. Bybit’s Response The exchange paused the compromised wallet but assured users that all other cold wallets were secure. Withdrawals remained open, indicating Bybit had backup reserves or alternative wallets unaffected by the hack. How Did This Hack Happen? This attack wasn’t a direct breach of Bybit’s infrastructure—it was a targeted, multi-stage compromise of all the individuals responsible for authorizing cold wallet transactions. The hackers most likely: Identified Every Multisig Signer The attackers somehow discovered who at Bybit had signing authority over cold wallet transactions. This could have been done through leaked internal documents, social engineering, or even surveillance. Infected Each Signer’s Device with Malware Every signer’s device was compromised before the transaction request was even made. This suggests a highly coordinated cyberattack involving phishing, trojans, or custom-built malware.you Manipulated the UI to Show a Fake Transaction The hackers altered the transaction details displayed in the multisig signing interface. The signers saw a normal wallet transfer, but in reality, they were approving a smart contract modification. Gained Full Control Over the ETH Cold Wallet By approving the manipulated transaction, the signers unknowingly handed over complete wallet control to the hackers. The attackers then emptied the wallet into an address they controlled. This method is particularly frightening because it didn’t rely on exploiting smart contract vulnerabilities or brute-force hacking. Instead, it exploited human trust in the multisig system, proving that even decentralized approval mechanisms can be tricked if the signers are compromised. How This Could Have Been Prevented This attack challenges long-standing assumptions about cold wallet security. Traditionally, multisig setups were considered the safest way to protect crypto assets, but this breach redefines cold wallet security and highlights several critical failures that could have been avoided. First, the failure of Bybit’s signers to independently verify the actual transaction details before approval. If the multisig system had enforced out-of-band verification—such as manually confirming transactions through a separate device or network—this attack might have been caught before execution. Second, the potential compromise of every signer’s device. This indicates a major operational security (OpSec) failure at Bybit. The exchange could have enforced hardware-based security keys, air-gapped transaction signing, or required signers to use dedicated, isolated devices for wallet approvals. Lastly, Bybit could have implemented stronger safeguards for smart contract modifications. Instead of allowing contract changes through the same multisig process used for transfers, a separate governance mechanism with time-locked execution could have given security teams enough time to detect and reverse unauthorized changes. Unfortunately, these precautions weren’t in place—or weren’t enough—to stop the attack. How Can Retail Investors Protect Themselves? This breach is a harsh reminder that trusting centralized exchanges comes with risks. If Bybit—a top-tier exchange—can be hacked, no exchange is completely safe. Here’s how you can safeguard your crypto holdings: 1. Move Your Crypto to a Self-Custodial Wallet Exchanges are honeypots for hackers. Keeping assets on a CEX means you’re at risk of losing everything overnight. Use a self-custodial wallet like CoinWallet to store your crypto 2. Use Cold Storage for Long-Term Holdings If you’re holding significant crypto investments, use a hardware wallet that remains offline. Avoid keeping large sums in hot wallets that are always online and susceptible to attacks. 3. Enable Multi-Factor Authentication (MFA) If you must use an exchange, activate 2FA (Two-Factor Authentication) to prevent unauthorized access. Use hardware security keys like YubiKey for an added layer of security. 4. Verify All Transactions Before Signing For users engaging in DeFi or multisig transactions, always verify the transaction hash manually before signing. Never assume that the UI is showing the correct details. 5. Beware of Malware and Phishing Attacks Hackers often use fake wallet updates, phishing emails, or malicious browser extensions to gain access to private keys. Always download wallets and software from official sources only. By following these practices, you ensure full control over your assets—without relying on third parties. The Future of Crypto Security: Time to Rethink Custody The Bybit hack wasn’t just another breach—it was a wake-up call for the entire industry. If an attack of this sophistication can succeed, no centralized exchange is truly safe. This event proves that "not your keys, not your coins" is more than just a mantra—it’s a survival rule in crypto. For serious investors, the path forward is clear: embrace self-custody. Move funds to hardware wallets, enable strict verification protocols, and stay vigilant against sophisticated attack vectors. Take Control of Your Crypto Today Don’t wait for another exchange hack to take action. Switch to a self-custodial wallet now and secure your assets against future threats.
Monthly Crypto Roundup by CoinsDo: Jan 2025

The cryptocurrency market carried its December momentum into January 2025, with continued price movements, regulatory shifts, and institutional interest shaping the landscape. However, the month also introduced new variables—including President Donald Trump’s sweeping tariff announcements and the surprising launch of his and Melania Trump’s memecoins—both of which sent ripples through the broader crypto ecosystem. Market Performance January saw Bitcoin (BTC) continue its rollercoaster ride, briefly reclaiming the $100,000 mark before retracing to around $94,500 by the month's end. This volatility was largely driven by speculation surrounding upcoming U.S. regulatory announcements and broader macroeconomic concerns. Ethereum (ETH) followed suit, experiencing price swings between $2,600 and $3,600. Other major cryptocurrencies, including Solana (SOL) and Avalanche (AVAX), posted impressive gains, largely fueled by growing interest in decentralized finance (DeFi) and non-EVM chains. Points of Interest Trump's Tariff Shock and Its Crypto Impact In late January, President Donald Trump announced a new round of tariffs on imports from Canada, Mexico, and China, citing economic and national security concerns. The measures included a 25% tariff on most imports from Canada and Mexico (with Canadian energy facing a lower 10% tariff) and a 10% tariff on Chinese goods. The move sent shockwaves through global markets, triggering volatility in equities, commodities, and crypto alike. Bitcoin initially dipped 4% following the announcement, reflecting broader risk-off sentiment among investors. Other cryptocurrencies, including Ethereum and XRP, saw even sharper declines, with ETH dropping 17% to $2,577 and XRP falling 18% to $2.38. Investors feared that rising trade tensions could lead to inflationary pressures and increased regulatory uncertainty, both of which could weigh on digital assets. However, some analysts believe that these tariffs could ultimately benefit Bitcoin in the long term. Historically, economic uncertainty and protectionist policies have driven demand for decentralized, borderless assets like BTC, which could see increased adoption as a hedge against geopolitical risk. The Trump Memecoin Phenomenon In an unexpected twist, President Donald Trump and First Lady Melania Trump entered the cryptocurrency space with the launch of their own memecoins—$TRUMP and $MELANIA. The tokens, which debuted in mid-January, quickly became the hottest topic in crypto, with $TRUMP’s market capitalization surging past $10 billion in its first few days. While supporters hailed the move as a mainstream validation of crypto culture, critics warned of the risks associated with sitting political figures launching speculative assets. Some within the crypto community raised concerns about potential conflicts of interest, as Trump’s administration actively shapes crypto policy while personally benefiting from the market. Others argued that the introduction of politically charged tokens could damage the industry’s credibility and reinforce the notion that memecoins are purely speculative assets with no intrinsic value. Despite the controversy, the launch of $TRUMP and $MELANIA reignited retail interest in memecoins, fueling price surges in similar assets like Dogecoin (DOGE) and Shiba Inu (SHIB). Institutional Adoption According to a report by Standard Chartered, Bitcoin is projected to hit $200,000 and Ethereum $10,000 by the end of 2025 as institutional investors increase their allocations to crypto-related exchange-traded funds (ETFs). MicroStrategy, a longtime Bitcoin advocate, added more than 10,000 BTC to its holdings, bringing its total to approximately 472,000 BTC. Security Concerns The crypto hacking scene, after a relatively quiet December, saw a resurgence in January. Centralized finance (CeFi) platform Phemex suffered losses totaling approximately $85 million after their hot wallets were breached. This incident underscores the vulnerabilities inherent in centralized custodial services, which, despite being perceived as safer options, remain attractive targets for cybercriminals. In response to these incidents, security experts recommend several best practices for users: Utilize Hardware Wallets: For long-term holdings, hardware wallets offer an added layer of security by keeping private keys offline. Stay Informed on Audits: Engage with DeFi protocols that undergo regular security audits to ensure the integrity of their smart contracts. Diversify Holdings: Distributing assets across multiple platforms and storage solutions can mitigate the risk of a single point of failure. Final Thoughts January 2025 proved that the momentum from the previous year is far from over. From major macroeconomic policies like Trump’s tariffs to the wild rise of political memecoins, the crypto market remains as unpredictable as ever. As institutional players double down, regulatory clarity remains a top concern, and the industry continues to grapple with balancing innovation, security, and financial stability. As the year unfolds, one thing is clear—crypto remains at the heart of the financial conversation, shaping and being shaped by the global economy in real time. 🚀
The Beginner's Guide to MPC Wallets
24 mins read
Welcome to "The Beginner's Guide to MPC Wallets", your essential starting point to explore the transformative potential of Multi-Party Computation (MPC) wallets. As digital security and privacy become increasingly vital in our connected world, MPC wallets are revolutionizing how we manage secure transactions and protect sensitive keys. This guide is designed to simplify the complexities of MPC wallets, making it accessible whether you're just starting out or looking to deepen your understanding. Along the way, we’ll uncover how these innovative wallets are shaping the future of secure digital interactions. Here’s what we’ll explore together: The Basics: A clear introduction to MPC and how it powers next-generation wallet solutions. Real-World Impact: Practical examples that showcase how MPC wallets are transforming industries. Benefits and Challenges: A balanced look at what makes MPC wallets a game-changer—and what to watch out for. The Road Ahead: Emerging trends and innovations that promise to push MPC wallets even further. Whether you’re a tech enthusiast, a blockchain advocate, or someone seeking a secure wallet solution, this guide will provide the knowledge you need to confidently navigate the world of MPC wallets. Let’s dive in! What is MPC? At its core, Multi-Party Computation (MPC) is a subfield of cryptography that allows multiple parties to jointly compute a function over their inputs while keeping those inputs private. The essence of MPC is to enable this collaborative computation without any single party having access to the others' data. MPC emerged from the field of cryptography in the 1980s. It was initially a theoretical concept, but over the years, it has evolved significantly, driven by both advances in computational power and a growing need for data privacy. Basic Principles of MPC Secret Sharing Secret sharing is a cryptographic protocol that plays a pivotal role in ensuring data privacy and security. It involves dividing a secret, such as a cryptographic key or a piece of sensitive information, into multiple parts, known as shares. These shares are then distributed among a group of participants. The key aspect of secret sharing is that the original secret can only be reconstructed when a sufficient number of these shares are combined together. This threshold is predetermined and ensures that no single participant can access the full secret on their own. Here are 2 of the most common secret sharing schemes in use today: Shamir's Secret Sharing Scheme Developed by Adi Shamir in 1979, this is one of the most widely used secret sharing schemes. It is based on polynomial interpolation in finite fields. In Shamir's scheme, the secret is transformed into a polynomial of degree d, where d is one less than the number of shares required to reconstruct the secret (this is also known as the threshold). For instance, if the threshold is 3, the polynomial will be of degree 2. Each share is a point on this polynomial. To reconstruct the original secret, a minimum number of shares equal to the threshold is required. These shares are used to interpolate the polynomial, and the secret is the constant term of this polynomial. Think of Shamir's method as a jigsaw puzzle. You have a picture (which is your secret) and you break it into many puzzle pieces. You give each friend a piece of the puzzle. Only when enough friends (the number you decide, like 3 or 4) come together and join their pieces, can they see the whole picture and find out the secret. If they have fewer pieces than needed, they can't see the full picture, so they can't guess the secret. Blakley's Secret Sharing Scheme Proposed by George Blakley around the same time as Shamir's, this scheme is based on geometric properties. In Blakley's method, the secret is represented as a point in an n-dimensional space. Each share corresponds to a hyperplane in this space. The intersection of at least n such hyperplanes (where n is the threshold) is a single point, which is the secret. Much like Shamir's method, unless the threshold number of hyperplanes (shares) is available, the secret cannot be determined. Blakley’s scheme is notable for its simplicity and the fact that it offers a different mathematical approach to secret sharing, rooted in geometric concepts. Blakley's method is like having a treasure map. You draw lines on the map, and where enough lines cross, that's where the treasure (your secret) is hidden. You give each friend a different line to add to the map. Only when enough friends (again, a number you decide) come together and draw their lines on the map, will they find the crossing point where the treasure is hidden. If not enough friends come together, they won't find the crossing point and can't find the treasure. Computational Trust Computational trust refers to the reliance on mathematical algorithms and protocols to establish and verify trust in digital environments. Unlike traditional trust, which is often based on personal experiences and subjective judgment, computational trust is built upon objective, algorithmically driven processes. In the context of blockchain technology, computational trust is exemplified by the use of cryptographic techniques and consensus algorithms. For instance, cryptographic methods like public and private key encryption ensure that transactions are secure and that identities are authenticated, thereby creating a trust layer over digital interactions. MPC itself is a cryptographic technique that distributes trust among multiple parties. No single party can compromise the computation or the privacy of the data. Additionally, consensus mechanisms, such as Proof of Work (PoW) or Proof of Stake (PoS), further reinforce trust. These mechanisms allow a network of decentralized and often anonymous participants to agree on the validity of transactions without needing a central authority, thus creating a trustless environment where participants can engage securely based on the assurance provided by the computational processes themselves. What is an MPC Wallet? MPC wallets are built on the foundational principles of Multi-Party Computation (MPC) technology, leveraging its cryptographic capabilities to redefine digital asset security. Unlike traditional wallets that rely on a single private key, MPC wallets split the key into encrypted shares distributed across multiple devices or participants. These shares collaborate through MPC protocols to authorize transactions without ever reconstructing the entire key, ensuring enhanced protection against theft, loss, and unauthorized access. By utilizing MPC technology, these wallets offer a secure and flexible solution for managing digital assets in an increasingly interconnected world. Witness MPC Wallets in Action Imagine a company with multiple departments, such as Research, Marketing, and Operations, each managing its own budget. To ensure robust security and shared accountability in treasury operations, the company adopts a Multi-Party Computation (MPC) wallet for fund management. In this setup, the wallet's private key is divided into key shards using MPC technology, with each shard distributed to the heads of different departments. When a department needs to initiate a transaction, at least two department heads must collaborate by using their key shards to authorize the transfer. This approach not only strengthens security—making it nearly impossible for unauthorized access even if one shard is compromised—but also promotes shared control and collective decision-making over company finances. The result is a wallet solution that fosters collaboration while streamlining operations. For a more straightforward application, consider a group of three friends managing a shared cryptocurrency investment. Each friend holds a shard of the wallet’s private key, requiring any two of them to approve transactions. This ensures that no single individual can act unilaterally, offering a balance of security and trust while managing shared assets. How MPC Works in Wallets At the heart of MPC wallets lies a process grounded in advanced cryptographic principles. Here’s how the technology enables secure and private collaboration: 1. Input Gathering Each participant contributes a private share of the key. In the context of wallets, these shares are created during the initial setup, with no single party ever holding the full private key. 2. Key Fragmentation The private key is divided into encrypted shards using cryptographic techniques, akin to breaking a secret into incomprehensible pieces. 3. Distributed Key Shares Each shard is distributed among the participants or devices, ensuring that no single entity can access or use the wallet independently. 4. Secure Computation When a transaction is initiated, the participants use their key shards to perform cryptographic operations collaboratively, authorizing the transaction without ever reconstructing the full private key. 5. Final Authorization The results of these computations are combined, allowing the transaction to proceed securely while preserving the privacy and security of the key fragments. The Top Benefits of Using MPC Wallets Multi-Party Computation (MPC) wallets are quickly gaining traction for their innovative approach to digital asset management. By leveraging advanced cryptographic techniques, MPC wallets offer a range of benefits that make them ideal for both individuals and businesses. Let’s break down the key advantages: 1. Enhanced Security MPC wallets eliminate the traditional reliance on a single private key by splitting it into multiple encrypted shares. These shares are stored across different devices or parties, ensuring that no one entity has complete control. This approach reduces the risk of theft, phishing attacks, or unauthorized access, as an attacker would need to compromise multiple shares simultaneously. 2. Resilience Against Single Points of Failure Traditional wallets are vulnerable to the loss or theft of private keys. With MPC wallets, the absence of a single key ensures that even if one share is compromised, the wallet remains secure. 3. Flexible Multi-Signature Functionality MPC wallets support collaborative decision-making by requiring multiple participants to approve transactions.This feature is especially valuable for organizations managing corporate funds or requiring layered security for high-value transactions. 4.

New Scam Alert on TON: Everything You Need to Know
3 mins read
Cryptocurrency exchanges face a constant battle to stay ahead of evolving security threats, and the TON bounce scam is one of the latest challenges targeting blockchain transaction mechanics. This sophisticated scam exploits vulnerabilities in how exchanges process deposits on the TON network, using a clever “double-spend” or “bounce” tactic to manipulate account balances. In this blog, we’ll dive into the inner workings of the TON bounce scam, exploring how it operates, why it’s effective, and—most importantly—what measures exchanges can implement to safeguard against this emerging threat. Read on to uncover the details and learn how to protect your platform and users. Mechanics of the Scam Initiating the Transaction The scammer sends a deposit of 1 TON (or similar token) from their address (the red box) to the exchange's deposit address (the green box). Creating the Bounce Effect The TON blockchain supports a "bounce" feature where a transaction that cannot be fully processed (e.g., due to lack of funds or smart contract restrictions) will return the tokens to the sender. This results in two parts to the transaction: Outgoing Transaction (Scammer → Exchange): The exchange detects this part as a deposit. Bounce Back (Exchange → Scammer): The TON blockchain mechanism sends the tokens back to the scammer's wallet. Exploiting Exchange Logic If the exchange's wallet system fails to recognize the second part of the transaction (the bounce), it will assume the deposit was successful and credit the scammer's account. The scammer then immediately withdraws the credited funds from the exchange before the error is detected. End Result The scammer's wallet balance remains the same (because the funds bounced back), but they gain additional funds credited by the exchange, effectively stealing assets. This is what an account that has engaged in such a scam before looks like: https://tonviewer.com/EQCWXzcOaG__xbHttae18kLzAHxIRVe-XF1bLbfAZ1n1gY_d Mitigation Strategies for Exchanges Pre-Post Balance Verification Ensure the exchange monitors both outgoing and incoming transaction statuses on the blockchain, including potential reversals or bounces. Smart Contract Validation Employ stricter validation rules to confirm that a deposit remains on the blockchain and has not been reversed. Delayed Credits Implement a short delay before crediting user accounts to confirm transaction finality, especially on blockchains with unique behaviors like TON. Auditing Deposit Logic Regularly review deposit-handling code to identify potential exploits, particularly for newer blockchains or unique transaction mechanisms. Final Thoughts By implementing the steps above, exchanges can significantly mitigate the risk of TON bounce scams. This method is efficient, secure, and adaptable to other potential network-specific quirks. Remember, there are a lot of people with bad intentions out there, so stay safe and take care!
