Blockchain security company CertiK's latest data shows that in May 2026, losses in the crypto industry due to hacking, exploitation of vulnerabilities, and fraud amounted to approximately $68.3 million, a decrease of nearly 90% compared to over $650 million in losses in April, making it the third month this year with losses below $100 million.CertiK stated that approximately $2.6 million in losses during May came from phishing attacks. In contrast, in April, significant attacks on Drift Protocol and KelpDAO's infrastructure resulted in losses of approximately $285 million and $292 million, respectively, with these two incidents accounting for about 95% of the total losses for that month, making April one of the worst months for losses since March 2022.Despite the reduction in large-scale attacks at the protocol level, CertiK warns that risks such as phishing attacks, social engineering scams, deepfakes, and credential leaks continue to grow. Researchers point out that an increasing number of attackers are targeting employees, operational systems

According to the data panel on the ChainCatcher official website, regarding BTC wallet balances, in the past 7 days, Bybit had the largest increase among the top 10 exchanges, reaching 4.91%, followed by Binance (+2.35%) and Bitfinex (+1.1%); Kraken had the largest decrease at 4.98%, followed by Bithumb (-1.87%) and Gemini (-0.6%).In terms of exchange asset transparency proof, in the past 7 days, only three exchanges had net inflows, namely Binance (+$303 million), Bitfinex (+$102 million), and Deribit (+$46.45 million); the top three for net outflows were OKX (-$187 million), Bitget (-$185 million), and Bybit (-$70.495 million).

On-chain analyst Axel Adler Jr stated in a recent report that the Bitcoin market has entered a significant volatility compression phase. The realized volatility over the past week (30-day moving average) has dropped from about 39 in early March this year to the current level of around 17, with a quarterly decline of over 56%, approaching historical low levels. Currently, the BTC price remains around $73,500, still below the approximately $79,500 200-day moving average. Historical experience shows that extremely low volatility often indicates that the market is accumulating energy, typically followed by a significant directional trend. However, volatility compression itself does not provide directional signals; it merely indicates that the market is about to make a new trend choice.Meanwhile, the Delta indicator, which reflects changes in market premiums (the difference between market capitalization growth rate and realized market capitalization growth rate), has been in negative territory for six consecutive months, further dropping to about -0.0013 in May. This indicator suggests that the growth rate of Bitcoin's market capitalization continues to lag behind the growth rate of realized market capitalization, indicating a contraction in market risk appetite and valuation premium.The current market exhibits a combination of "low volatility + cooling premiums," which is not a typical overheated bull market structure but rather resembles a consolidation phase after emotional cooling. If BTC subsequently returns above the 200-day moving average, and Delta rebounds to near zero, it will indicate that the market has re-entered a risk appetite expansion cycle; conversely, if volatility releases downward and Delta continues to deteriorate, it may enter a deeper risk-averse phase.In summary, Axel Adler Jr stated that the current market direction remains neutral, but the degree of compression is at a high level, and the probability of significant directional volatility in the future is continuously increasing.

According to monitoring by PeckShield, there were a total of 40 major hacking incidents in the cryptocurrency sector in May, with total losses of approximately $81.7 million, a decrease of 87.4% compared to $647 million in April. Among them, cross-chain protocols remain the main target of attacks, with 8 major cross-chain attacks causing losses of $33.28 million, accounting for 41% of the total losses for the month.Significant loss events include SUPERFORTUNE AI (approximately $15.18 million), Verus-Ethereum Bridge (approximately $11.58 million, already refunded), and THORChain (approximately $10 million), among others.

According to Cointelegraph, CertiK data shows that losses from attacks on crypto platforms in May dropped to $68.3 million, a nearly 90% decrease from $650 million in April. May became the third month in 2026 with losses below $100 million. Of this, approximately $2.6 million came from phishing attacks, and about $9.4 million of stolen funds have been recovered or returned. The largest single loss in May came from the Verus Protocol cross-chain bridge attack, with $11.5 million stolen; THORChain ranked second, with $10.1 million stolen. Code vulnerabilities were the highest loss type, accounting for about $45 million, or 66%; wallet or private key leaks resulted in $13.7 million in losses. Cross-chain bridges were the primary target of attacks, with losses of $28.6 million, accounting for 42%. DeFiLlama data shows that there were a total of 29 incidents in May, of which 7 involved private key leaks.

Analyst Darkfost stated that since September 2025, the inflow of stablecoins from million-level whales on Binance has halved, dropping from approximately $62 billion per month to $33 billion, indicating a significant reduction in the participation of large whales in the cryptocurrency market.When a large amount of stablecoins flows into trading platforms, it usually indicates that the market is regaining interest and is about to be repriced. A decrease in inflow suggests that large capital is exiting the market. Monitoring whales remains one of the best ways to gauge potential market sentiment. Currently, the US-Iran conflict and its ripple effects are still creating a lot of uncertainty, making risk management crucial.

According to Jinshi reports, the weekly change in ADP employment in the United States for the week ending May 9 was a decrease of 35,750, while the previous value was a decrease of 42,250.

According to The Block, since the KelpDAO cross-chain bridge attack in mid-April, the total value locked (TVL) in DeFi has decreased by about 14%, from approximately $172 billion to $148 billion. The attackers exploited vulnerabilities in off-chain infrastructure rather than smart contract vulnerabilities, stealing about $292 million and exposing new infrastructure risks.The outflow of funds has continued for more than five weeks, indicating that investors are broadly withdrawing marginal capital rather than just targeting specific protocols that were attacked. Lending, as the largest DeFi category, saw its locked amount decrease from about $53 billion to $40 billion, marking the largest decline. Liquidity re-staking protocols also experienced significant drops. The KelpDAO attack indicates that as the security of smart contracts improves, off-chain infrastructure is becoming a more easily exploitable attack surface.

According to Jinshi News, Chris Turner from ING stated in a report that the prospects for a Federal Reserve interest rate hike are increasingly strengthening, which is expected to support the dollar. Even with news of specific progress in peace negotiations between the U.S. and Iran, the dollar should not have much room for decline.He pointed out that Federal Reserve Governor Waller warned in a recent speech that if oil prices remain high, the possibility of an interest rate hike cannot be ruled out. At the same time, due to economic fragility, investors have lowered their expectations for interest rate hikes in the Eurozone and the UK.

According to BBX data, corporate Bitcoin reserves are under pressure, intertwined with the continuous outflow of ETF funds, leading to an overall cautious sentiment in crypto concept stocks. The core dynamics are as follows:Trump Media & Technology Group, Corp. (NASDAQ: $DJT) transferred 2,650 BTC (approximately $205 million) to a Crypto.com exchange address on May 22. The company's official statement described this as a "transfer rather than a sale," part of an expanded trading strategy, but the actual disposal method remains to be confirmed as of the report deadline. On-chain data shows that the funds have arrived at the Crypto.com exchange address. Previously, the company transferred 2,000 BTC (approximately $175 million) to Crypto.com about four months ago. The Q1 2026 financial report (May 9, CoinDesk) indicates that as of March 31, the company held 9,542.16 BTC (with a fair value of $647.1 million, and a purchase cost of approximately $1.13 billion); after this transfer of 2,650 BTC, Arkham's on-chain estimate of the remaining holdings is about 6,889 BTC (approximately $532 million). The Q1 financial report also disclosed a net loss of $405.9 million (compared to a loss of $31.7 million in the same period last year) and revenue of only $871,200. The company originally purchased 11,542 BTC at an average price of about $118,522, with a total purchase cost of approximately $1.37 billion, and the current holdings are still significantly discounted compared to the cost; during the same period, the company withdrew its ETF applications for Bitcoin, Ethereum, and Solana from Truth Social.The U.S. Bitcoin spot ETF recorded over $2.26 billion in net outflows in the two weeks ending May 23, ending a streak of seven consecutive weeks of net inflows. During this period, Bitcoin fell from about $82,500 (the recent high on May 6) to $74,305 (on May 23), a decline of about 10%, marking the lowest point since April 20. The iShares Bitcoin Trust (NASDAQ: $IBIT) under BlackRock, Inc. (NYSE: $BLK) has seen its holdings decrease from a peak of about 812,000 BTC to about 800,000 BTC, still accounting for approximately 62% of total assets in U.S. Bitcoin spot ETFs. CoinDesk analysts attribute this round of outflows to high U.S. Treasury yields (with the 10-year yield touching 5.01%) and systemic deleveraging driven by geopolitical pressures, rather than a weakening belief in Bitcoin's long-term logic.

According to the data panel on the ChainCatcher official website, regarding BTC wallet balances, in the past 7 days, among the top 10 exchanges by balance, only Gemini saw a decline, with a decrease of 0.25%; Bybit had the largest increase, reaching 2.65%.In terms of exchange asset transparency proof, in the past 7 days, the top three net inflows were Bybit (+$393 million), Bitget (+$342 million), and HTX (+$13.14 million); the top three net outflows were Binance (-$236 million), Gate (-$98.43 million), and Deribit (-$72.20 million).

On May 14, BNB Chain released the "BSC Post-Quantum Cryptography Migration Report," stating that it has completed the migration testing for quantum-resistant cryptography for transaction signatures and the consensus layer, using the NIST standardized post-quantum signature algorithm ML-DSA-44 (Dilithium) and the pqSTARK aggregation scheme.The report shows that BSC has replaced transaction signatures from ECDSA to ML-DSA-44 and switched consensus voting aggregation from BLS12-381 to pqSTARK to address the potential threats posed by future quantum computing to the existing elliptic curve cryptography system. However, post-quantum signatures also significantly increase the on-chain data volume: the size of a single transaction has increased from about 110 bytes to approximately 2.5KB; the block size in a 2000 TPS scenario has increased from about 130KB to around 2MB; and the TPS in the testing environment has decreased by about 40%-50%.BSC stated that the current network bottleneck mainly comes from the larger transaction data propagation, rather than the consensus protocol itself. Meanwhile, the consensus layer aggregation still maintains high efficiency, with pqSTARK achieving a signature compression ratio of about 43:1, and the additional burden on validators remains within a controllable range. The report concludes that existing technology can achieve "quantum-resistant" deployment for blockchain, but future issues related to network bandwidth and data scalability still need to be addressed.

Ionic Digital released an unaudited mining and operational update report for April 2026, disclosing that 20.45 bitcoins (BTC) were mined in April, a decrease of 27.1% compared to the previous month. The average daily hash rate was 1.51 EH/s, a month-on-month decrease of 26.2%, mainly due to the complete shutdown of its hosting facility in GXD, Oklahoma, which is currently out of operation.Currently, the company has only four mining sites in Midland still operating, which contributed all 20.45 BTC output in April. During the same period, global network hash rate decreased by 2.1%, but block output remained basically stable, with a month-on-month increase of 0.5%. In terms of finances, Ionic Digital maintained a zero-debt status, having not sold any BTC in April. As of April 30, the company held 2,836.4 BTC, an increase of approximately 19.9 BTC compared to the previous month.
