废除美国国税局针对去中心化金融平台规定的法案已在参议院获得批准，为总统的预期签署奠定了基础。 3 月 26 日，参议院以 70 票对 28 票通过了废除备受争议的 DeFi 经纪人规则的议案，该规则旨在扩大该行业企业的纳税报告要求。 本月早些时候，众议院在两党的支持下通过了这项决议，共和党众议员迈克·凯里（Mike Carey）是该法案的直言不讳的批评者，他称这是“政府大规模越权”，将损害美国公民的隐私并阻碍该行业的发展。 现在，该决议将提交给唐纳德·特朗普总统进行最终批准。白宫加密和人工智能顾问戴维·萨克斯此前已确认政府将支持该决议，预计特朗普将签署该决议成为法律。 该规则最初由美国国税局和美国财政部于 8 月提出，并于 2024 年 12 月最终确定，要求 DeFi 平台向美国国税局报告用户交易（具体来说是加密货币销售的总收益），类似于传统经纪商。 你可能还喜欢：美国众议院投票推翻 IRS 的 DeFi 经纪人规则 这将包括收集和归档参与这些交易的用户的个人数据，批评人士称，这违背了去中心化的本质，并给通常没有中央运营商的平台带来不必要的压力。 废除该规则的支持者认为，该规则在实践中不可行，并可能会阻碍美国创新。 数字资产倡导组织区块链协会与德克萨斯州区块链委员会去年起诉了美国国税局。 该协会的法律主管玛丽莎·科佩尔 (Marisa Coppel) 去年在一份联合声明中批评了监管机构，声称美国国税局和财政部“超越了其法定权限，扩大了‘经纪人’的定义”。 他补充道：“这不仅侵犯了使用去中心化技术的个人的隐私权，还会将整个新兴技术推向海外。” 阅读更多：白宫支持取消 2024 年 12 月通过的臭名昭著的 DeFi 经纪人规则

SecondSwap announced on Tuesday its expansion to the Avalanche blockchain ecosystem following a successful launch on Ethereum earlier this year. The integration is designed to offer a transparent and accessible secondary market for tokens subject to vesting schedules or early contributor lockups, crypto.news can exclusively report. According to a Tokenomist report earlier this year, the sector is estimated to hold more than $100 billion in value. SecondSwap is a decentralized exchange focused on locked and vesting digital assets. Following its launch on Ethereum (ETH) in February, SecondSwap’s expansion to Avalanche (AVAX) introduces native smart contracts designed for managing token lockups, secondary trading, and price discovery directly on-chain. Bringing transparency to locked token trading Traditionally, trading locked tokens has been limited to private, off-market transactions. The downside is that it often lacks transparency and carries settlement risks. “Today’s secondary market for locked tokens remains largely manual, opaque, and inefficient,” Kanny Lee, Founder of SecondSwap, said in the press release. “SecondSwap is transforming this model by bringing locked token trading fully on-chain, with smart contract execution that delivers transparent pricing, verifiable asset transfer, and real-time settlement.” Projects using SecondSwap can issue, price, and trade locked assets without relying on third-party services. Investors can benefit from a platform offering a bidding mechanism that allows users to propose discounts and select preferred vesting periods. Lot sizes consist of three, six, and 12 month lockup periods which means better access for a broader range of investors, not just institutional participants. Early users who whitelist their wallets and place bids can potentially access discounted tokens compared to prevailing market prices. Expansion supports Avalanche’s DeFi growth plans Justin Kim, Head of Asia at Ava Labs, said the launch fits into Avalanche’s broader strategy to expand DeFi infrastructure and support tokenized asset markets. “SecondSwap perfectly aligns with Avalanche’s mission to digitize, democratize, and de-risk asset ownership,” he said. SecondSwap’s expansion follows a $1.2 million seed funding round led by GSR and Animoca Ventures. The company says it plans to continue building tools to support on-chain lifecycle management for token projects, aiming to reduce volatility tied to unlock events and improve overall market efficiency.

埃隆·马斯克的 SpaceX 将派遣一个由四人组成的团队执行极地轨道任务，资金由比特币矿池 F2Pool 的创始人王春提供。 一支由四名宇航员组成的团队正准备进行一次不同寻常的太空之旅，这是人类从未尝试过的旅程：直接飞越地球的南北极。这项任务由埃隆·马斯克的 SpaceX 执行，名为 Fram2，资金来自马耳他的加密货币投资者王春，他通过比特币 (BTC) 挖矿发家致富。 该团队搭乘 SpaceX 太空舱升空，其中包括王在极地探险中认识的三位探险家：挪威电影制片人 Jannicke Mikkelsen、德国机器人研究员 Rabea Rogge 和澳大利亚探险家 Eric Philips。他们之前都没有去过太空。 此次任务定于美国东部时间周一晚 9:46 从佛罗里达升空，机组人员将踏上一条人类航天器从未走过的路径。虽然一些卫星使用极地轨道进行地球观测，但人类任务通常沿着更接近赤道的路径飞行。Fram2 将瞄准真正的 90 度倾角，这意味着它将直接飞越两极。 F2Pool 一度发展成为比特币网络中最大的挖矿池之一，贡献了网络相当一部分的哈希率。 比特币矿池分布 | 来源：Hashrate Index 但随着美国和俄罗斯矿工的崛起，比特币挖矿领域的竞争愈发激烈，F2Pool 的作用也变得越来越小。根据 Hashrate Index 的数据，如今，它仅占比特币总哈希率的 10% 多一点。 你可能还喜欢：比特币矿工在减半前创纪录赚了 20 亿美元 已开采超过 7,000 BTC 目前尚不清楚 Chun 为这次为期数日的飞行支付了多少钱。在 2022 年接受 Staking Rewards 采访时，Chun 表示，在 F2Pool 成立的头两年里，他“亲自开采了 7,700 枚比特币”，截至发稿时价值约为 6.4 亿美元，不过 Chun 承认，他卖掉了早期开采的所有 BTC。 “2013 年 1 月，我卖掉了 2011 年和 2012 年的所有比特币，并偿还了我的初始贷款。我从父母那里借了一些钱来构建第一个 GPU 配置。我记得当时卖出的价格大概是 11 美元。” Chun Wang 此次太空任务提供了多种研究机会。例如，机组人员将参与太空旅行对人体影响的研究，包括脑液转移和睡眠中断。他们将接受类似于 SpaceX 2024 年北极星黎明号任务的 MRI 扫描。 As early as March 31st at 9:46 p.m. ET, SpaceX will launch Fram2, the first human spaceflight mission to explore Earth from a polar orbit.

More than 60% of astronauts experience nausea in microgravity. Astronauts experiencing severe symptoms may use anti-nausea injections, but these can cause grogginess. The Fram2 team hopes to contribute to developing better treatments. 太空领域的性别差距 此外，此次任务还将包括英国初创公司 Hormona 的一项实验，旨在追踪女性宇航员的荷尔蒙波动。米克尔森和罗格将在飞行过程中使用尿液测试纸。 Hormona 联合创始人 Jasmine Tagesson 在接受 CNN 采访时表示，此次飞行可能有助于缩小“医学领域的性别数据差距”，因为在 700 多名前往太空的人中，只有约 15% 是女性。不列颠哥伦比亚大学医学教授 Jerilynn Prior 博士指出，太空中的压力因素可能会扰乱排卵。“至少，相关的压力可能会缩短黄体期，”她说。 除了医学研究之外，Fram2 还将进行一系列实验，包括在太空中种植蘑菇、在微重力环境下测试锻炼程序以及从轨道上观察极光。 此外，机组人员还将尝试记录史蒂夫极光现象，这是 2016 年发现的一种神秘极光现象。卡尔加里大学空间物理学专家埃里克·多诺万博士指出：“从太空拍摄极光的照片尚未广泛进行。” The crew is expected to spend three to five days in orbit before returning to Earth with a splashdown in the Pacific Ocean. 阅读更多：BitMEX：未知组织控制 47% 的比特币哈希率

A high-profile House hearing on crypto regulation got testy Tuesday after House Democrats, led by Rep. Maxine Waters walked out in protest over President Donald Trump’s involvement in crypto. The joint hearing — organized by the House Financial Services and Agriculture Committees — was meant to discuss a new draft of market structure legislation that would divide oversight of digital assets between the Securities and Exchange Commission and the Commodity Futures Trading Commission.  But, for a moment, the debate on regulatory frameworks was interrupted and marked by political tension. Waters, the ranking Democrat on the Financial Services Committee, formally objected to the hearing at its outset.  “I object to this joint hearing because of the corruption of the President of the United States and his ownership of crypto and his oversight of all the agencies,” she said during the session, before exiting with other Democratic members. During a heated exchange, Waters kept “insisting on the objection,” citing dubious ties between Trump and the crypto industry.  You might also like:21Shares launches ETP giving exposure to Crypto.com’s CRO    Partisan concerns over crypto The walkout followed Waters’ earlier warning to Committee Chair French Hill that she would oppose the session unless Republican lawmakers agreed to include language addressing Trump’s financial ties to crypto.  Those ties have come under increased scrutiny in recent months, with Trump and his wife, Melania, launching their own memecoins, and a pro-Trump financial group, World Liberty Financial, unveiling a stablecoin.  Trump also held a crypto fundraising dinner Monday night, with prices reportedly reaching $1.5 million per plate. Hill responded by defending the bipartisan nature of the legislative efforts, saying the new draft “places universal requirements on issuers of all stripes” and should not be derailed by political disputes, according to Politico.  You might also like:UK rules out Bitcoin reserves: not ‘appropriate for our market’ Democrats against GENIUS Democrats have also expressed concerns about the GENIUS Act, a proposed stablecoin bill that aims to set federal standards for issuance and compliance. Over the weekend, several Democratic senators, including Mark Warner and Raphael Warnock, flagged issues such as the need for stronger anti-money laundering rules and stricter oversight of foreign issuers. Waters is reportedly planning a separate “shadow hearing” to highlight what she sees as conflicts of interest surrounding Trump’s crypto activities. Joint hearings in the House require unanimous consent, but the hearing is still going at the time of writing.  You might also like:Crypto staking firm Figment eyes $100m to $200m acquisition deals with ‘smaller providers’

Pepe 是加密货币中第三大模因币，由于近期的下跌趋势失去了动力，其在过去两周内表现波动。 Pepe（PEPE）维持在关键支撑位 0.000010 美元，较 12 月高点下跌 65%。 此次下跌导致其市值蒸发近 60 亿美元，从 100 亿美元跌至 41 亿美元。这反映了更广泛的 meme 币市场，因为大多数代币在过去两个月内都崩盘了。 Pepe 的抛售恰逢期货未平仓合约大幅下降，表明投资者需求减少。未平仓合约已从 1 月份的 5.56 亿美元下降到今天的 2.58 亿美元。该指标追踪期货市场所有未完成的看涨和看跌期权订单，可洞察市场情绪。 从积极的一面来看，许多 Pepe 持有者似乎都坚持持有。CoinCarp 的数据显示，Pepe 持有者的数量已从上个月的 384,000 人攀升至 404,100 人。 你可能还喜欢：这就是为什么 Solana 价格面临 40% 崩盘风险 Pepe 价格技术面发出混合信号 Pepe 价格图表 | 来源：crypto.news 日线图显示，Pepe 的价格已从 12 月的 0.00002828 美元回落至 0.000010 美元。最近，随着 50 天和 200 天加权移动平均线交叉，它形成了死亡交叉模式，这是技术分析中历史上的看跌信号。 持续的盘整表明佩佩可能正在形成看跌旗形形态，其特点是急剧下跌，随后出现一段时间的横向波动。这种形态通常预示着进一步下跌。 进一步加剧了看跌预期，Pepe 已跌破 61.8% 斐波纳契回撤水平 0.000011 美元，表明空头仍占主导地位。这些技术模式表明可能跌至 0.0000058 美元，这是去年 8 月创下的最低波动水平。 不过，也有看涨逆转的情况。Pepe 已形成下降楔形模式，其趋势线汇聚，通常是突破的前兆。如果这种情况发生，Pepe 可能会反弹至 0.000025 美元，较当前水平上涨 150%。 你可能还喜欢：Bitcoin funds lead $415m outflows as Fed signals tighter policy
