Ethereum recently rejected from a key confluence zone, including the 0.618 Fibonacci level. With price back under the point of control, traders are watching closely for signs of a deeper move or a trap.Ethereum’s (ETH) price action has stalled at a technically significant region, the 0.618 Fibonacci retracement level, drawn from the most recent pivot high to low. This area is also reinforced by daily horizontal resistance and a descending VWAP, adding to its weight as a decision zone. After several failed attempts to push higher, ETH has now begun to roll over, trading back under the point of control (POC) of the local range. Key technical points Major Resistance Cluster:The 0.618 Fibonacci aligns with daily resistance and a descending VWAP, forming a strong technical ceiling. Loss of POC:Price has fallen below the volume point of control, indicating sellers are gaining control of the short-term auction. Bearish Structure Building:Lower highs and a stalled breakout raise the probability of a move toward the next key support near $1,540. ETHUSDT Chart (4), Source: TradingView Detailed analysis After an impulsive move higher, Ethereum’s price has spent several sessions consolidating below a heavy resistance zone. The 0.618 Fibonacci level, a widely watched retracement marker, is reinforced by daily horizontal resistance and a declining VWAP drawn from the last major high. This confluence attracted notable selling pressure, and ETH has now failed multiple times to break above.What adds further caution to the current structure is the recent loss of the point of control within this region. Price has now dipped below the highest-volume node of the recent range, suggesting that the market is no longer accepting value at these levels. This often precedes range rotation or continuation in the direction of the rejection, in this case, to the downside. You might also like:Bitcoin consolidates below key resistance as lower timeframe trend develops The technical landscape also reveals a clear short-term bearish structure forming. ETH has been unable to print higher highs or maintain higher lows, increasing the probability of a broader correction. The next logical support level sits around $1,540, not only a structural level from previous sessions but also a zone with visible price inefficiencies (e.g., unfilled fair value gaps and single prints) that could act as magnets for price.This setup opens the door for a potential 10% downside move from current levels, especially if the recent swing low fails to hold. Still, traders should remain alert to the possibility of a fakeout, as Ethereum has previously shown sudden strength from similar rejection zones. What to expect in the coming price action Ethereum’s failure to break out above the 0.618 confluence zone and its rejection from the POC suggest a higher chance of rotation toward lower supports. If price breaks below the recent swing low, the $1,540 region could be the next target. However, if buyers can defend current levels and reclaim the POC, this might prove to be a local fakeout before resuming upward. For now, caution is warranted as price hovers near a decisive level.

随着白宫数字资产峰会的临近，参议员伊丽莎白·沃伦致信大卫·萨克斯，质疑他与加密公司 Bitwise 的关系。 Axios 援引沃伦的信函获悉，在白宫首届数字资产峰会于 3 月 7 日星期五举行前的几个小时，参议员伊丽莎白·沃伦（民主党 - 马萨诸塞州）向唐纳德·特朗普政府的白宫人工智能和加密货币沙皇戴维·萨克斯发送了一封信，对潜在利益冲突表示担忧。 In the letter, Warren questions how the federal government’s increasing involvement in blockchain could benefit existing cryptocurrency holders, potentially creating conflicts of interest. She specifically asked Sacks about his connections to the industry, zeroing in on his past links to crypto companies. “The planned Crypto Strategic Reserve is just the most recent example of a Trump Administration crypto policy with the potential to benefit a wealthy, well-connected few at the expense of taxpayers.” 伊丽莎白·沃伦 萨克斯是一名特殊政府雇员，不受一些道德规范的约束，包括与财务披露相关的规范。 沃伦指出，他之前在 Craft Ventures 担任的职务曾受到严格审查，该公司支持 Fold、Lightning Labs 和 Bitwise 等加密货币公司，而 Bitwise 的前五大持股与特朗普总统最近宣布的战略加密货币储备中提到的五种代币相匹配。 参议员还想弄清萨克斯或任何参与储备政策的人是否在宣布之前进行了与这些资产相关的交易。 “尽管您通过 X 发表了公开声明，但目前仍不清楚您个人何时撤资 BTC、ETH 和 SOL，Craft Ventures 何时撤资 Bitwise，以及您身边的人是否“可能持有头寸并在最近的价格飙升中抛售”。 伊丽莎白·沃伦 沃伦进一步强调，美国证券交易委员会的立场应该保护创建模因币的公司和个人免受潜在的诉讼，这可能会直接使特朗普总统的货币企业受益，例如特朗普官方币（TRUMP）和梅拉尼娅币（MELANIA）。 预计白宫加密货币峰会将于美国东部时间 3 月 7 日星期五下午 1:30 至下午 5:30 举行。 你可能还喜欢：White House Crypto Summit: Nic Carter reacts to March 7 Bitcoin reserve announcement As crypto.news reported earlier, U.S. President Donald Trump has signed an executive order to establish a Strategic Bitcoin Reserve. The reserve will be funded with Bitcoin (BTC) seized by the federal government through asset forfeiture, which means that taxpayers won’t incur any costs. Per Sacks, the U.S. government currently holds around 200,000 BTC, though no full audit has been conducted yet. The executive order requires a complete accounting of federal digital asset holdings and forbids the sale of Bitcoin in the reserve, comparing it to a “digital Fort Knox.” Read more:分析师称，到 2030 年，美国战略加密储备可能通过黄金销售增加 100 万比特币

FTX 的破产成本接近 10 亿美元，使其成为美国历史上最昂贵的第 11 章案件之一。 法庭记录显示，已向负责此案的法律和金融公司支付了近 9.48 亿美元，迄今为止已批准超过 9.52 亿美元的费用。据彭博社报道，尽管成本高昂，但大多数客户预计能收回 118% 的索赔，这在破产程序中是罕见的结果。 高额费用源于追回分散在复杂账户网络中的数十亿美元资产的努力。律师和财务顾问在这一过程中发挥了至关重要的作用，以大幅折扣购买 FTX 债权的对冲基金是受益者之一。 FTX 上周开始向债权人进行首次分配，但法律团队仍在继续追踪额外资产。 你可能还喜欢：Fold 又购买了 10 个比特币，目前持有的比特币数量已超过 1,000 个 沙利文和克伦威尔 据彭博社报道，FTX 的首席律师事务所 Sullivan & Cromwell 已获得超过 2.48 亿美元的报酬，而财务顾问 Alvarez & Marsal 已获得约 3.06 亿美元报酬。负责监管客户索赔和其他债权人事务的律师事务所收取了约 1.1 亿美元的费用。 2008 年金融危机期间，苏利文·克伦威尔律师事务所在指导美国财政部和主要金融机构方面发挥了关键作用。该公司协助摩根大通收购贝尔斯登，并协助政府救助美国国际集团。 此外，该公司还在历史上最重大的公司欺诈案之一安然公司破产后提供法律和财务咨询。 FTX 案的成本远远超过其他加密货币破产案的成本，包括 Celsius、Genesis、BlockFi 和 Voyager Digital，这些公司合计的费用约为 5.02 亿美元。 该破产公司仍面临正在进行的诉讼，其中包括针对币安的 18 亿美元诉讼。 据彭博社报道，虽然 FTX 的成本相当高昂，但仍远低于雷曼兄弟 60 亿美元的破产成本——这是美国历史上最昂贵的破产案。 你可能还喜欢：加密货币犯罪：中国男子在韩国进行加密货币交易时被杀
