Last week, funds have flowed into #Bitcoin, #Ethereum, and #Hyperliquid.

According to Hyperinsight monitoring, the whale address starting with 0xc278 has completed 61 BRENTOIL trades since trading Brent crude on March 19, of which 59 were long positions and only 2 were short positions, with a long position ratio of 96.7%. The total net loss from all 61 trades is approximately $2.431 million, with positions worth over $1 million accounting for 99.4% of the total loss. Yesterday morning, its Brent long positions triggered a system liquidation again. The entire liquidation closed out 47,600 BRENTOIL long positions, with a liquidation turnover of about $4.046 million, a weighted liquidation price of approximately $84.99, and a total loss of around $275,000. After the liquidation, the address no longer holds any Brent positions. Before the liquidation, BRENTOIL on Hyperliquid dropped from a high of $91.68 to a low of $82.81 on Sunday, with a maximum decline of 9.7%; its final backup liquidation price was about 7.6% lower than the high. This round of decline mainly occurred after Trump said he would suspend a new round of strikes on Iran and that a Middle East ceasefire agreement was near. The whale had three long positions in early April that lost about $882,000, $513,000, and $460,000 respectively, but afterward it still almost only went long on crude oil, repeatedly recording the largest single liquidation on the network.

CryptoQuant analyst Darkfost said short-term Bitcoin holders transferred more than 32,000 BTC to centralized exchanges (CEX) on August 1 at a loss, marking one of the largest sell-off loss events in the past month.

Bitcoin hardware wallet manufacturer Coldcard tweeted that the past three days have been among the most difficult in the company’s history, with some users losing years of savings. The team has been in constant contact with customers since last Friday, assisting in transferring still-secure funds and providing recovery guidance. The company has now destroyed remaining Coldcard inventory produced using vulnerable firmware and suspended shipments. Satscard, Opendime, and Tapsigner are unaffected. The released patch firmware prevents newly generated mnemonics from being impacted, but old mnemonics created on the vulnerable firmware remain at risk; users are required to create new wallets and transfer their funds. The company temporarily recommends alternative hardware wallets including Bitkey, Ledger, Trezor, Jade, and Bitbox, and urges affected users to retain their devices to support future recovery efforts.

According to statistics from Onchain Lens, losses from the Coldcard hardware wallet vulnerability have reached $88.6 million. Four attack waves have been recorded so far: The first and second waves saw 1,158.81 BTC stolen from 2,673 victims; the third wave involved 207.73 BTC from 293 monitored P2WSH vaults; the fourth wave remains unconfirmed, possibly affecting 462 victims and totaling 388.93 BTC.

Nvidia Senior Vice President Gilad Shainer announced at a recent tech forum that Co-packaged Optics (CPO) has entered mass production. Switches developed by Nvidia in collaboration with its supply chain have begun delivery to key partners and are already deployed internally at the company. Switches equipped with CPO technology are expected to be widely deployed in AI data centers globally starting this year. Shainer noted that the biggest opportunity in the future optical communications market lies in vertical scaling (Scale-up), which requires over ten times the bandwidth efficiency of horizontal scaling (Scale-out). Shainer previously led R&D at Mellanox; after Nvidia acquired the firm, he headed the AI Platform Network Transmission division and co-developed the COUPE silicon photonic packaging platform with TSMC. This announcement helps dispel market concerns over optical communications specification upgrades and boosts the operational outlook for related vendors. It is reported that Nvidia has already integrated CPO into its Spectrum-X switches, with the goal of supporting the upcoming large-scale deployment of the Vera Rubin AI platform, which delivers at least three times the computing speed of the GB300. Trendforce projects that the CPO/NPO market will exceed $39 billion by 2030, with growth momentum accelerating significantly between 2028 and 2029 as vertical scaling drives the adoption of optical interconnects. Separately, according to BIT (bit.com) market data, as of press time, CPO-related stocks posted modest pre-market gains: AAOI rose 2.63%, LITE gained 1.92%, and MRVL increased 2.4%.

According to on-chain analyst Ai Yi (@ai_9684xtpa), two new addresses opened a cumulative 5x long position in KAITO worth $6.94 million (notional value: $7.106 million) on Hyperliquid in the early hours of today, becoming KAITO’s two largest positions. Both addresses sourced their margin from OKX. KAITO has plunged nearly 20% in the past 24 hours, rapidly trimming its month-to-date gains, leaving the two addresses with an unrealized loss of $991,000.
