A PANews daily roundup put several crypto and tech developments in focus, led by strong U.S. spot ETF flows and a new market data feature on X. According to SoSoValue, U.S. spot Bitcoin exchange-traded funds recorded $999 million in net inflows on Sept. 21 Eastern Time, extending the streak to three straight days. BlackRock’s IBIT led with $381 million, while ARKB from Ark Invest and 21Shares added $289 million. Spot Ether ETFs also posted $270 million in net inflows the same day, with BlackRock’s ETHA and Fidelity’s FETH leading the list. On the product side, X rolled out live quote displays for stocks and cryptocurrencies. The feature includes a trading button that routes users to Coinbase, Gemini, Kraken, Moomoo and Interactive Brokers. The roundup also covered a Bloomberg report that the U.S. Department of Justice is investigating whether Binance may have violated Iran sanctions, a governance incentive proposal vote launched by World Liberty Financial, xAI’s release of Grok 4.7, and fresh revenue figures from the Bittensor ecosystem. In market data and on-chain activity, PANews highlighted a 14-year-dormant wallet moving 600 BTC, a brief USDe depeg on Binance, and new ETH accumulation by BitMine and several whale addresses.

Google has been fined €403 million by Ireland’s Data Protection Commission, according to a Techub News brief citing Crypto Briefing. The penalty stems from an investigation into how the company handled users’ location data. Ireland’s regulator said Google’s conduct breached the European Union’s General Data Protection Regulation, or GDPR. The report did not provide additional details on the specific practices at issue, but it identified the handling of location data as the focus of the case. The fine adds to the list of major GDPR enforcement actions taken by European regulators against large technology companies. In this case, the Irish DPC was the authority named in the report, and the amount of the penalty was specified as €403 million.

Marvell said on Aug. 4 that it has launched the Bravera SC6 SSD Controller, model MV-SF1410, aimed at the PCIe Gen6 NVMe SSD market for AI data centers, hyperscale cloud operators, and enterprise database deployments. The company said the chip is built for a shift in AI system design toward tiered memory architectures, where NVMe SSDs act as a high-capacity memory layer rather than serving only as conventional storage. According to Marvell, that setup can provide tens to hundreds of terabytes of capacity at a lower cost than GPU HBM and DRAM, helping keep GPUs utilized while reducing infrastructure costs. Bravera SC6 supports PCIe Gen6, remains backward compatible with PCIe Gen1 through Gen5, and complies with the NVMe 2.2 specification. It also features 16 NAND channels, transfer speeds of up to 3600 MT/s, support for ONFI and Toggle NAND, and compatibility with SLC, MLC, TLC, and QLC flash. Marvell said samples are expected to become available in the fourth quarter of 2026.

Fears that quantum computers could soon crack Bitcoin keep resurfacing, but the source article argues the gap between theory and practical attack capability remains vast. In theory, the hardware required to break elliptic curve cryptography, or ECC, has fallen sharply, from about 317 million physical qubits in 2022 to fewer than 500,000 in a 2026 paper. That is a major change on paper. The problem is that current machines can only run real algorithms with about 105 usable qubits, leaving several orders of magnitude still missing. The article walks through what would actually be needed to run Shor’s algorithm against ECC, including logical qubits, error correction, decoding speed, and the production of magic states needed for non-Clifford gates such as Toffoli gates. It says the 2026 design would require around 1,200 logical qubits, about 90 million sequential Toffoli gates, roughly 500,000 physical qubits under current error-correction assumptions, and a runtime measured in minutes. It also separates abstract cryptographic risk from actual wallet exposure. For Bitcoin, addresses only become vulnerable once a public key is revealed on-chain, which is why the article highlights roughly 6.7 million BTC as already exposed. Ethereum faces a related issue because it uses the same secp256k1 curve and ECDSA signatures, while its persistent account model makes repeated address use more common.

A TechFlowPost article translated from Derrick Cui argues that practical quantum attacks on elliptic curve cryptography, or ECC, are still several orders of magnitude away even after major theoretical advances. The piece says recent research has cut the estimated hardware needed to break ECC from about 317 million physical qubits in 2022 to fewer than 500,000 in 2026, but today’s machines can run real algorithms on only about 105 qubits. It walks through what would actually be required to attack ECC with Shor’s algorithm, including logical qubits, error correction, decoding, Toffoli gates and magic-state distillation, then compares those requirements with current hardware. The article also discusses what a quantum break would mean for Bitcoin and Ethereum. In Bitcoin, the main risk is tied to addresses whose public keys have already been revealed on-chain, while Ethereum’s persistent account model would leave any wallet that has sent a transaction exposed if quantum attacks were available today. The piece concludes that the gap between theory and deployable machines remains enormous, and that no reliable timeline can be inferred from current progress alone.
