Former Ripple CTO David Schwartz emphasizes the neutrality of XRP as a crucial factor in its adoption by countries wary of using currencies controlled by rivals for trade settlement. According to NS3.AI, XRP functions as a politically neutral settlement infrastructure, making it attractive to nations aiming to mitigate geopolitical risks linked to dominant national currencies such as the U.S. dollar. The integration of XRP by banks and countries is viewed as a strategic necessity rather than a speculative endeavor.

Despite a significant drop in silver prices, retail investors have poured nearly $500 million into the silver market over the past week. According to Jin10, Vanda Research data indicates that during the six trading days ending Thursday, retail investors invested $430 million into the largest silver ETF, SLV. This includes over $100 million on January 30, when silver prices fell by 27%, marking the largest single-day decline in history. StoneX analyst Rhona O'Connell noted that silver's allure continues to attract investors. She added that the appeal of silver has increased due to its 'massive sell-off,' with some investors viewing it as an opportunity to buy at lower prices.

CoinSharesのレポートによると、実用的な量子コンピュータの出現可能性は、ビットコインのセキュリティへの潜在的影響に関する議論を引き起こしている。ビットコインの量子脆弱性は差し迫った危機ではなく、予見可能な技術的課題であり、調整のための十分な時間がある。技術的には、量子リスクの主因はShorアルゴリズムによるECDSAまたはSchnorr署名の解読で、これにより秘密鍵が暴露される可能性がある。影響を受けるのは主にP2PKアドレスを早期に使用した約170万BTC（総供給量の約8%）であり、短期的にはシステム的な市場衝撃を引き起こす可能性は限定的だ。供給量の25%がリスクに晒されているという主張は明らかに誇張されており、アドレス移行によってリスクは軽減できる。長期攻撃は今後10年以内に理論的に可能となるが、mempool内で10分以内に秘密鍵を解読する短期攻撃は今後数十年は依然として不可能である。秘密鍵漏洩により市場に流入する可能性のある規模は約1万BTCであり、価格体系への影響は限定的である。保有者は安全なアドレスへ自主的に移行可能。残りの標的は約3.4万アドレスに分散しており、量子技術の突破があっても全面攻撃の完了には数十年を要する可能性がある。

Block Inc., the payments company led by Jack Dorsey, is notifying hundreds of employees about possible job eliminations as part of its annual performance reviews. According to Cointelegraph, this move is part of a broader restructuring initiative aimed at enhancing operational efficiency and aligning product lines. Bloomberg reported on Sunday that up to 10% of Block's workforce could be impacted, citing sources familiar with the situation. As of late November, the company employed just under 11,000 people, according to an executive at the time. The restructuring comes as Block seeks to integrate its peer-to-peer payments platform, Cash App, more closely with its merchant services arm, Square. Additionally, the company is expanding newer ventures, including its Bitcoin mining division, Proto, and an artificial intelligence project known as Goose. Despite these changes, Block's shares saw a nearly 5% increase on Friday, according to Google Finance. Block is set to release its quarterly earnings on February 26, as reported by Bloomberg. Analysts anticipate an adjusted profit of approximately $403 million, or 68 cents per share, on revenue of around $6.25 billion for the fourth quarter. In the previous quarter, Block reported a net income of $461.5 million on $6.11 billion in revenue, with gross profit rising 18% year over year. This growth was driven by a 24% increase in Cash App and a 9% rise in Square, although the stock experienced a decline post-release due to some performance metrics not meeting Wall Street expectations. Bitcoin remains a significant revenue stream for Block, generating about $1.97 billion in revenue for the third quarter, down from $2.4 billion the previous year. By the end of September, Block held 8,780 BTC, valued at over $1 billion, and recorded a $59 million quarterly valuation loss. In November last year, Square, Block's payments platform, introduced a Bitcoin payment option for merchants, enabling them to accept BTC directly at checkout through its point-of-sale terminals. This launch complements earlier tools that allow merchants to convert a portion of daily card sales into Bitcoin, as part of Square's broader payment and wallet ecosystem. Currently, more than four million sellers across eight countries utilize Square's services.

Analysts forecast Block to post $403 million in Q4 profit on $6. 25 billion revenue, following a third quarter marked by strong gross profit growth but mixed market reaction. source: https://cointelegraph.com/news/jack-dorsey-block-may-cut-10-percent-staff-restructuring?utm_source=rss_feed&utm_medium=rss&utm_campaign=rss_partner_inbound
