KiloEx 向香港警方报告 700 万美元被盗事件，承诺向用户赔偿

Strategy（前身为 MicroStrategy）旗下股票 MSTR 下跌逾 5%。不仅如此，在 BTC 跌破 90,000 美元后，MSTR 的市值与其比特币持有量的比率已降至 1.6。 根据雅虎财经的数据，Strategy 的股票在盘前交易中下跌了 5.65%。截至今日美国东部时间下午 16:00，Strategy 的股价为 282.76 美元。据信 Strategy 股价暴跌是由比特币 (BTC) 价格下跌引发的，2 月 25 日，比特币价格曾跌至 87,630 美元。 比特币的下跌不仅影响了 Strategy 的股价，还影响了其溢价率。Michael Saylor 的公司长期以来与比特币保持着密切联系，因为它以持有 BTC 的最大公司而闻名。自 2024 年底以来，这家软件开发公司拥有 BTC 总供应量的 2% 以上。最近，它购买了 20,356 枚比特币，购买时价值近 20 亿美元。 不幸的是，加密货币分析师 Miles Deutscher 表示，在最近的比特币价格暴跌之后，Strategy 可能不得不抑制比特币的购买狂潮。 $MSTR 的市值与其基础的 $BTC 持有量的溢价已从 11 月份的 3.4 的高位跌至现在的 1.6。这个数字越低，Saylor 筹集更多资金购买 $BTC 的难度就越大。看来他必须放慢脚步了。pic.twitter.com/yljEAgHyot— Miles Deutscher (@milesdeutscher) 2025 年 2 月 25 日 你可能还喜欢：Strategy 以 19.9 亿美元增持 20,356 枚比特币，扩大企业 BTC 持有量 根据Deutscher的分析，MSTR的溢价市值与比特币持有量的比率已从11月份的峰值3.4大幅下降至2月25日的1.6。这意味着该股票的市值现在更接近其比特币持有量的实际价值，而不是被高价推高。 Deutscher 在最近的帖子中表示：“这个数字越低，Saylor 筹集更多资金购买 BTC 的难度就越大。” 由于比特币价格下跌，如果比特币价格不能在短期内反弹，该公司将很难发行股票或利用其股票来筹集购买更多比特币所需的资金。此外，投资者不会愿意支付超过比特币当前内在价值的价格，从而限制了 Saylor 筹集资金的能力。 正如 crypto.news 之前报道的那样，比特币在 2 月 25 日下跌了 6.78%。Matrixport 分析师警告称，BTC 可能会经历更深的下跌，尤其是在交易活动低迷限制了逢低买入需求的情况下。 阅读更多：加密货币清算总额已超过 10 亿美元，加密货币为何会崩盘？

众议院共和党人和民主党人都提出了监管美国稳定币的提案，表明该领域是唐纳德·特朗普总统任期内的立法重点。 据 Punchbowl News 报道，众议院金融服务委员会资深民主党人马克辛·沃特斯 (Maxine Waters) 发布了一项提案，提议通过货币监理署、联邦存款保险公司和美联储等联邦监管机构对稳定币进行监管。 沃特斯的讨论稿还概述了州监管机构的监管框架。早在 2022 年，沃特斯众议员就批评了共和党领导的众议院委员会法案，称该法案“存在严重问题”，因为人们担心允许州监管机构在没有美联储监督的情况下批准稳定币。当时，她在前委员会主席帕特里克·麦克亨利面前辩称，这种方法可能会带来不可预见的风险。 你可能还喜欢：Bitwise CIO：美国稳定币法案可能会超越比特币 ETF 的影响 沃特斯众议员的提议意味着自特朗普总统上任以来，共和党和民主党议员都已引入了稳定币监管规定。 上周，众议院金融服务委员会新任共和党主席弗伦奇·希尔 (French Hill) 提交了一份稳定币监管法案草案，由众议员布莱恩·斯泰尔 (Bryan Steil) 共同发起。该法案将授予 OCC 批准和监督支付稳定币发行者的权力。 具体来说，OCC 可以向持有联邦许可证的非银行稳定币运营商颁发许可证并进行监管。这些规定可能允许 Ripple 等公司进入这个价值 2200 亿美元的市场。 希尔众议员的法案与沃特斯众议员的提议形成鲜明对比，因为该法案将稳定币监管权交给了美国货币监理署，而不是沃特斯所提倡的美联储。沃特斯此前表示，众议院立法者需要就稳定币达成“大协议”，才能推进监管。

一名 30 多岁的韩国男子因诈骗加密货币投资者 29.3 亿韩元（约合 204 万美元）被判处三年监禁。 昌原地方法院根据《特定经济犯罪加重处罚法》判处该男子（仅被认定为 A 人）犯有欺诈罪。 据《国际日报》报道，他假扮为一位富有的投资专家，引诱通过在线聊天室认识的受害者，并承诺保证本金并提供 30% 至 50% 的年回报率。 2021 年 12 月至 2023 年 8 月期间，A 共 324 次从投资者那里获得资金。他声称这笔钱将用于加密货币投资，但实际上，他没有资产或工作，并且在之前的加密货币投资中已经损失了数十亿韩元。 你可能还喜欢：特朗普贸易战担忧加剧，加密货币融资利率暴跌 “利息”支付 为了赢得受害者的信任，A 将部分资金以“利息”的形式偿还，实际上是将这笔钱用于类似庞氏骗局的骗局。 法院指出，虽然部分资金已退还，但由于还款方式迂回，损失不能视为已弥补。 负责裁决的法官金成焕表示，实际获利远低于诈骗总额。受害者不太可能获得全额赔偿。 你可能还喜欢：币安联合创始人回应批评者指责该平台导致 ACT、TST 和其他货币价格下跌

IOTA’s upcoming Rebased upgrade could be its most ambitious yet, replacing centralization with decentralization and unlocking smart contracts for a future-ready blockchain. On May 5, IOTA will activate Rebased, a protocol upgrade that marks the project’s most ambitious departure from its original architecture since its inception in 2015. More than just a technical milestone, Rebased appears to be a foundational pivot — one that replaces legacy components, modernizes the network stack, and reframes the network’s broader identity in the crypto landscape. Once branded as a “blockchain without blocks,” IOTA’s earlier value proposition hinged on the promise of a feeless, scalable network powered by the Tangle, a directed acyclic graph designed to process transactions in parallel rather than sequentially. But that promise came with its caveats: the project spent years shackled to a centralized Coordinator node that acted as a gatekeeper for transaction finality. Despite efforts like Coordicide, IOTA struggled to fully convince skeptics that it could deliver decentralization and developer traction at the same time. With Rebased, the developers want to change that narrative. What’s coming for IOTA The Rebased upgrade transitions IOTA to a delegated proof-of-stake model where validators are elected by token holders. With the Coordinator gone for good, network security and consensus now rest on a decentralized set of nodes, each accountable to the community. It’s the first time in IOTA’s history that the network will finalize transactions without any centralized fallback. Yet, consensus is just one layer of this overhaul. The real headline may be what’s now possible on top of IOTA’s new layer. Rebased introduces native smart contract capabilities through MoveVM, a virtual machine that runs the Move programming language originally developed by Meta for its failed Diem project. By choosing Move over Ethereum-style EVM compatibility, IOTA seems to betting on long-term sustainability over immediate compatibility. Key features of MoveVM | Source: IOTA You might also like:IOTA integrates Nansen to bring advanced on-chain analytics to users Smart contracts on IOTA will run directly on layer-1, rather than via sidechains or bridged networks like it works with Ethereum. This puts IOTA on a path to compete more directly with other layer-1 networks like Aptos (APT) or Sui (SUI), which also use Move. Transaction costs would remain near zero, while the protocol would still allow tipping validators to prioritize transactions, ensuring fair processing during sudden demand spikes that outpace gas price adjustments. “The protocol would still allow for tipping validators for prioritization, ensuring transactions can be processed fairly when demand spikes faster than the protocol can adjust gas prices.” IOTA Scalability, long touted but rarely successfully realized, also gets a practical upgrade. The Mysticeti consensus algorithm, introduced with Rebased, targets over 50,000 transactions per second with sub-second finality under normal conditions. Both Solana and IOTA’s Rebased network require similarly robust infrastructure for their validator nodes, including 24-core CPUs, 128 GB of RAM, 4 TB of storage, and 1 Gbps internet connections. What IOTA’s Rebased means for regular users For everyday users, the transition will be pretty noticeable. The Firefly wallet — once the primary interface for IOTA — will be deprecated. Users are expected to migrate to a new browser-based IOTA Wallet, designed to support the Rebased protocol natively. Moreover, the migration isn’t automatic: users must back up their Firefly wallets using stronghold files, mnemonics, or exported keys before the upgrade goes live. Anyone relying on Ledger hardware wallets will also need to manually install a new version of the IOTA Ledger app, especially since Ledger Nano S support is being sunsetted in Ledger Live. There’s also a long-awaited change in how IOTA holders interact with the network: staking. For the first time, token holders can lock up their assets to earn rewards, and more critically, to influence validator selection, introducing new economic alignment between the protocol and its participants, something IOTA has lacked until now. IOTA Rebased tokenomics | Source: IOTA The minimum staking requirement to become a validator would be set at 2 million IOTAs, with an initial cap of 150 validator seats. Validators can meet the minimum staking requirement through delegators’ stake contributions, allowing for flexibility in participation. Exchanges supporting IOTA will pause deposits and withdrawals during the upgrade window but are expected to resume shortly after the mainnet transition. Trading activity, however, should continue uninterrupted. For a project often criticized for over-promising and under-delivering, Rebased is a moment of redefinition. It turns IOTA into a decentralized, programmable, scalable layer-1 protocol with real developer tooling and economic incentives. It’s not a patch or optimization. It’s a clean break. The stakes are high: if successful, Rebased could finally turn IOTA into what it always aspired to be: a general-purpose decentralized network that competes on technical merit, not just white paper vision. And if not, the crypto space is less forgiving today than it was in 2017. Read more:IOTA announces network upgrade for more real-world adoption
