Bitcoin Flash Crash: Nearly $527 million Liquidated Across the Network in One Hour, Mainly Long Positions

Since September, multiple long-dormant Bitcoin wallets have initiated transfers one after another, with September 19 being no exception. Before a transfer from a 2011 wallet, four other early P2PKH (Pay-to-Public-Key-Hash) wallets each moved 25 BTC, totaling 100 BTC. All four transactions were confirmed at block height 967722. These four wallets were all created in February or March 2013, a period marked by high Bitcoin price volatility and the peak of the Cyprus banking crisis in March 2013. On March 1, 2013, Bitcoin traded at roughly $32, rising to $91.95 by March 31. On-chain data shows the four P2PKH addresses acquired the 100 BTC at an extremely low cost. Just 10 blocks later, at block height 967732, an even older wallet transferred 100 BTC. Created on November 2, 2011, this address moved the 100 BTC in a single transaction from a P2PKH address to a newer P2WPKH (Pay-to-Witness-Public-Key-Hash) wallet. The Bitcoin was originally acquired at just $3.24 per coin. The funds were then fully transferred, with the wallet utilizing the "send all funds at once" feature. It is reasonable to infer that the four 25-BTC transfers, which later flowed into the same wallet, belong to the same entity. This aggregation transaction ultimately landed in a P2WPKH wallet belonging to custodian BitGo.

Ethereum co-founder Vitalik Buterin responded in a post to Paradigm CTO Georgios Konstantopoulos’ question—“What room is there left for privacy going forward?”—stating that privacy only truly dies when one gives up on it. “I will not give up on privacy; instead, I will double down on it,” he added. Earlier reports noted that Vitalik updated Ethereum’s roadmap in August, with quantum security, privacy protection, and native Rollups identified as future priorities.

At the 2026 World Manufacturing Conference, Changxin Technology announced the official mass production of its fifth-generation technology platform. The company stated that it has achieved a 11.95-nanometer half-pitch for the active area of its memory array, a 45:1 aspect ratio for memory capacitors, and reduced the height of the core active region to 6762 nanometers. Meanwhile, the fifth-generation process platform has seen a significant improvement in storage density: under equivalent conditions, the yield per wafer has increased by more than 50% compared to the previous generation platform. The 24GB LPDDR5X products built on this platform have entered formal mass production and are now fully adopted in domestic mainstream flagship smartphones. (The Paper)

According to official announcements, Genius.fun has launched the "Genius Alpha" exclusive tag to provide projects with higher visibility. Projects that receive this tag will get a dedicated category and prominent placement on the platform, helping the community improve recognition amid the large number of tokens launched daily. Genius.fun noted that its launchpad has lowered the barrier to token issuance, but it has also made it harder for genuinely dedicated teams to distinguish themselves from projects seeking quick cash-outs. Genius Alpha uses a straightforward differentiation signal: project teams pay $300 to gain additional exposure. The platform also emphasized that the payment only represents the project team’s investment and does not guarantee the project’s quality. Genius Alpha is part of its roadmap, and the platform will later provide more tools to support project launches, organizational operations, and the advancement of business goals. The platform believes that making tokens easy to create is just the first step; helping the community use tokens to achieve longer-term goals will be the focus of its next phase.
