美国证券交易委员会批准现货以太坊 ETF 期权交易

华尔街分析师上调了对经济衰退的预测，此举可能会影响比特币和其他流行的山寨币，如柴犬币、狗狗币、瑞波币和卡尔达诺。 PIMCO 分析师将经济衰退的可能性上调至 35%，摩根大通经济学家则认为经济衰退的可能性为 40%。高盛则将经济衰退的可能性上调至 20%。 穆迪著名经济学家马克·赞迪 (Mark Zandi) 也认为可能性为 35%。大多数分析师都提到了消费者信心持续下降、政府削减开支以及唐纳德·特朗普的贸易战。 技术性衰退的定义是连续两个季度出现负增长。亚特兰大联储的一项流行指标估计，本季度美国经济将萎缩 2.4%。 在经济衰退时期，柴犬、狗狗币、XRP 和卡尔达诺的交易情况如何？ 经济衰退的特征是经济出现负面状况，包括高失业率、生产力疲软以及消费者信心下降。 然而，比特币（BTC）和柴犬币（SHIB）、狗狗币（DOGE）、瑞波币（XRP）和卡尔达诺（ADA）等山寨币很有可能在经济衰退期间表现良好。 这是因为美联储可能会通过降息和重启量化宽松政策（也称为 QE）来干预市场。量化宽松是指美联储通过购买政府债券、抵押贷款支持证券和其他资产来创造货币并将其注入经济的情况。 你可能还喜欢：RED 价格在一天内发生一系列变化后飙升 18%，交易量增长超过 200% 当美联储增加市场流动性时，加密货币、股票和其他风险资产往往表现良好。一个很好的例子就是 2008-2009 年的全球金融危机。虽然股市在经济衰退开始时暴跌，但在美联储和联邦政府干预后反弹。 同样，比特币的价格在新冠疫情爆发时也一度暴跌，但直到 2021 年才出现强劲反弹。 美联储今年降息幅度超过预期的可能性越来越大。周三公布的经济数据显示，美国2月份通胀率降至2.8%。 此外，美元指数和美债收益率近期均有所下跌，增加了美联储采取更为鸽派基调的可能性。 这些山寨币已经崩盘 SHIB vs DOGE vs ADA vs XRP 图表 | 资料来源：crypto.news 经济衰退将发生在 SHIB、DOGE、XRP 和 ADA 等山寨币在过去几个月暴跌之时。Shiba Inu 的价格已从今年的最高水平下跌了近 70%。DOGE、XRP 和 Cardano 也已从 2024 年的高点下跌了 50% 以上。 除了美联储可能降息外，这些现在被视为便宜货的货币还可能从其他潜在事件中受益。例如，唐纳德·特朗普提议建立战略比特币储备 以及大量流行的美国硬币。 此外，美国证券交易委员会已撤销多起加密货币诉讼，并可能在今年晚些时候批准一系列山寨币 ETF。这些催化剂可能会帮助推高比特币和山寨币的价格。 你可能还喜欢：《华尔街日报》：特朗普家族正就币安股份进行谈判，力促赦免捷克总统

Solana 联合创始人 Anatoly Yakovenko 对第 2 层解决方案的必要性提出了质疑，他认为经过优化的第 1 层可以充分满足速度、成本和安全性要求。 争论始于 rip.eth 在 X 上发帖称“没有理由构建 L1”，因为第 2 层提供了更好的速度、安全性和成本效率，而没有新共识机制的负担。他引用了 Eclipse，一个利用 Solana (SOL) 虚拟机的以太坊 (ETH) 第 2 层，作为优化扩展方法的一个例子。 In response to the lost, Yakovenko argued that a well-optimized layer-1 can be more secure, faster, and less expensive, pushing back on the idea that layer-2s are the best scaling solution. He noted that layer-2s frequently introduce security risks through fraud proofs and multisigs and rely on a slow-moving data availability layer. https://twitter.com/aeyakovenko/status/1903854829480583607?s=46&t=nznXkss3debX8JIhNzHmzw 你可能还喜欢：Solana 的 SIMD-228 提案旨在将 SOL 通胀率降低 80%，但未能达到批准门槛 当被问及区块链数据限制时，他驳斥了人们的担忧，称 Solana 每年产生约 80TB 的数据，对于建立业务来说太少，但对于个人来说又太多，无法轻松存储。关于存储，他澄清说，Solana 的账本与其状态是分开的，可以转移到 Filecoin 等去中心化存储提供商。 Yakovenko 的观点与以太坊联合创始人 Joseph Lubin 的观点截然不同，后者认为第 2 层对于扩展至关重要。在最近的数字资产峰会上，Lubin 表示以太坊是 Rollup 的最佳平台，因为它的安全性很高。他重申了自己的信念，即以太坊的未来在于第 2 层扩展。 尽管雅科文科心存疑虑，但第 2 层已经在 Solana 上首次亮相。Solaxy 是一种新的扩展解决方案，于 2 月筹集了 1900 万美元，它在链下处理交易，然后在 Solana 的主网上结算，以减少拥堵。 The need for a layer-2 like Solaxy arises from the significant growth of decentralized finance and memecoins on Solana, which has strained the network’s capacity and occasionally caused outages. 尽管即将到来的 Firedancer 升级有望将 Solana 的吞吐量提高到每秒 100 万笔交易，但拥塞仍然是一个问题。一些开发人员认为，为了避免拥塞并确保长期可扩展性，仍然需要第 2 层解决方案。 阅读更多：Solana 的首个元 DEX 聚合器 Titan 软启动，承诺零费用路由

The crypto market took a hit today as Bitcoin dropped below a key support level, weighed down by profit-taking and broader macro concerns. On Thursday, May 15, afternoon Asian time, the total crypto market cap slid by 4.8% to $3.39 trillion. Bitcoin (BTC) dipped 1.6% to around $101,846, losing the $103,100 support level.  Analysts are now watching the $101,600 mark as the next crucial level that it needs to hold to keep the recent bullish momentum alive. This dip comes right after the latest U.S. Consumer Price Index (CPI) data was released. Inflation for April came in lower than expected, rising just 2.3% year-over-year—the slowest pace since 2021, and down from March’s 2.4%. While low inflation can be a good sign, it also hints at weakening consumer demand, which could point to underlying recession fears. Interestingly, even though Trump’s new tariffs haven’t fully trickled down to consumer prices yet, the softer inflation print probably won’t be enough to convince the Federal Reserve to cut interest rates, despite pressure from Trump. Rate cuts are something the crypto traders have been hoping for, since lower rates usually boost liquidity and risk appetite. Investors are also in wait-and-see mode as they await the U.S. Producer Price Index (PPI) data coming out later today at 12:30 PM UTC. The report should give more clues about inflation, which could play a big role in what the Fed decides to do next with interest rates. Most market experts believe the Fed is likely to keep interest rates steady, and that’s prompted many traders to lock in profits, especially after Bitcoin’s strong run above the $100,000 mark.  While most of the market is sliding, some altcoins may be better positioned to ride out the downturn.

The SEC recently reduced Ripple’s fine to $50 million, effectively ending the long-running lawsuit and reinforcing XRP’s non-security status. XRP will also be in the spotlight this week as investors watch for the upcoming launch of CME’s XRP futures on May 19 and await a key SEC decision on a proposed ETF linked to XRP next month. On the daily chart, XRP has bounced back nicely after hitting a low of $1.6218 in April. It’s now trading above both the 50-day and 100-day moving averages, which is a bullish sign. XRP price, 50-day and 200-day EMA chart — May 15 | Source: crypto.news XRP has also formed an inverse head-and-shoulders pattern, a classic signal that often points to a trend reversal. The “head” is around $1.62, and the two “shoulders” are near the $2 mark. While the rally could keep going, there’s also a chance XRP might dip to retest the $2.21 support level before moving higher again. This kind of move, known as a break-and-retest, is actually seen as a strong bullish setup. If current trends hold, XRP could climb back to its year-to-date high of $3.40, reflecting a potential 36% upside from its current price. Tron (TRX) TRX has gained steady traction in this bull cycle, supported by TRON’s expanding role in the stablecoin market and rising on-chain activity. The network recently surpassed Ethereum in total USDT supply, cementing its position as a key infrastructure for stablecoin transfers, particularly in emerging markets. Other bullish drivers include TRON’s growing integration with real-world asset platforms and its sustained dominance in daily active addresses and transaction count, which have consistently outpaced most layer-1 networks in 2025. On the daily chart, TRX has bounced back nicely from support at $0.21, climbing to nearly $0.28 this week. It finally broke above the $0.25 resistance level, which had been a tough resistance level since January. TRX price, 20-day and 50-day EMA chart — May 15 | Source: crypto.news Tron is now trading inside an ascending channel and sitting just below the top of that range. It’s also moved above the 20-day and 50-day EMAs, which usually signals strength. If TRX breaks above the $0.28 level, it could push higher toward the $0.45 mark, last year’s high, which would be a 66% jump from current prices. Dogecoin (DOGE) Dogecoin (DOGE) has surged over 42% in the past month and was trading at $0.22 when writing. The rally comes amid rising institutional interest. Grayscale recently launched a dedicated Dogecoin trust, while 21Shares partnered with House of Doge to introduce DOGE-based exchange-traded products in global markets. Separately, the Dogecoin Foundation is working to advance real-world adoption of the original memecoin. In collaboration with House of Doge, it aims to onboard one million retailers through the Dogebox toolkit, an open-source solution for integrating DOGE payments. All of these point to a maturing ecosystem, where Dogecoin has evolved from its memecoin roots into a credible player within the broader decentralized landscape. On the daily chart, DOGE has broken above $0.242, a key resistance level it struggled with back in March. DOGE price, MACD, and RSI chart — May 15 | Source: crypto.news It’s also formed a textbook head-and-shoulders pattern over the past few weeks. In technical analysis, this setup often points to a potential trend reversal or continuation. Adding to the bullish signs, both the MACD and RSI indicators are pointing upward. The RSI is currently at 62, which suggests there’s still room for more upside. With this momentum, DOGE is well-positioned to return to its year-to-date high of $0.436, which would translate to a 93% rally from current levels.
