Galaxy Digital launches $5 million fund to advance research and development of quantum-resistant security for Bitcoin.

According to on-chain monitoring, a newly created wallet address 0x448a withdrew 74,900 HYPE tokens from Galaxy Digital, valued at approximately $4.39 million, and subsequently transferred them to Coinbase.

According to official announcements, OKX has now launched large withdrawal protection and after-hours withdrawal protection. Large withdrawal protection allows users to independently set a 24-hour cross-channel cumulative withdrawal threshold, with a maximum equivalent of $10 million. After-hours withdrawal protection enables KYC-verified users to set a daily protection period of up to 12 hours, during which operations including on-chain withdrawals, C2C sales, API withdrawals, and Pay top-ups will be blocked. Users can configure these features in the "Security Center" → "Advanced Security Settings" section.

According to monitoring by OnchainLens, following the Summer Fi attack on July 6, the attacker stole approximately 6.017 million DAI, and has since been converting and transferring funds via Tornado Cash. Currently, the remaining funds in the attacker’s wallets include: 11.3 ETH (valued at around $21,600) held in the original wallet, and 282.9 ETH (worth approximately $543,500) in a second wallet.

According to monitoring by The Data Nerd, wallet address 0x2684 has been steadily accumulating ETH and WBTC since June 30, with its current unrealized profit exceeding $12.5 million. The whale has purchased a total of 54,449 ETH (valued at roughly $94 million, at an average price of ~$1,726) and 600 WBTC (worth ~$38.37 million, with an average purchase price of ~$63,950). The position turned to unrealized profit after the whale added to its holdings during a market downturn.

Crypto Quant analyst Axel Adler Jr noted in a post that Bitcoin has recently entered a low-volatility compression phase. The 30-day average of its 1-week realized volatility has fallen to 28.3, a roughly 31% drop from the June 25 peak of 41.6. The metric has also retreated to around the 8th percentile of its historical distribution since 2016, meaning 92% of past trading days saw higher volatility than current levels. Meanwhile, Bitcoin’s 30-day momentum of open interest (OI) relative to market capitalization has been negative for 21 consecutive days, signaling market leverage is continuing to decline rather than accumulating amid the low-volatility environment. The cryptocurrency’s current price has rebounded approximately 11.4% from its June low, but this uptick has not been paired with an expansion of derivative positions, reducing the risk of a large-scale liquidation cascade. However, Bitcoin remains below its 200-day moving average of $72,666. If volatility rises back above 35 while the price fails to hold above the long-term moving average, downside risks could increase.
