Crypto Twitter (now X) has always been a place where someone with an illustrated animal for a profile picture can explain why your financial future depends on a token you just learned about. Now X’s Cashtag links are shortening the route from that conversation to a crypto exchange.Kraken joined X’s US Cashtag partner program on Sept. 16, giving users another route from tickers such as $BTC to its exchange. Tapping a Cashtag can bring up posts and a price chart on X, while the trading link sends users to Kraken’s app or website, where they sign in or register and…

In brief The Fed raised its benchmark rate 25 basis points to 3.75%-4% on a unanimous 12-0 vote Wednesday, its first hike since July 2023, after traders priced in a 93% chance of the move. Bitcoin briefly touched $76,499 after the announcement before settling near $76,300, roughly flat on the day as the broader crypto market held above $2.6 trillion. Zcash surged as much as 23% toward $1,425 after Paradigm co-founder Matt Huang disclosed his firm’s ZEC stake, calling the token “a private complement to Bitcoin.” Bitcoin traded near $76,300 on Thursday, largely unmoved a day after the Federal Reserve…

In brief King Charles III hosted representatives from Nvidia, OpenAI, Anthropic, and Google DeepMind at Dumfries House in Scotland on September 17, urging them to keep AI “firmly in the service of humanity.” The summit, organized by the Ditchley Foundation, came days after Anthropic CEO Dario Amodei’s essay calling on AI labs to deliberately slow capability gains, a call OpenAI’s Sam Altman and xAI’s Elon Musk both endorsed. The gathering produced no binding agreements — delegates only discussed whether a shared set of guiding principles could be established. King Charles III spent Thursday playing AI safety diplomat.The monarch hosted senior…

In brief OFAC has designated BitBank, an Iranian exchange controlled by financier Babak Zanjani. Treasury says Zanjani used it to move hundreds of millions in Bitcoin to the IRGC between June and July. The Hormuz toll authority has been routing its payments through the exchange since June. The U.S. Treasury has sanctioned BitBank, naming the Iranian exchange it says carried the Bitcoin that shipping companies paid for safe passage through the Strait of Hormuz.Since June, the Office of Foreign Assets Control said, the Hormuz Safe Marine Services Authority has used BitBank to pass the payments it collects on to the…

In brief Solana’s target slot time—the window a validator gets to produce a block—dropped from 300 milliseconds to 250 on Friday, the network’s third speed cut since August. The change makes blocks arrive nearly 17% faster but doesn’t raise how many transactions the network can process, since each shorter slot now carries proportionally less computation. A further cut to 200 milliseconds has no mainnet date and will only proceed if block-skip rates—how often a validator misses its turn—stay in check. Solana’s internal clock just ticked faster. Earlier Friday, the network’s target slot time dropped from 300 milliseconds to 250, a…

In brief Over five days in August, Bitcoin rose 24.6% while coin-denominated open interest fell 12.6%, meaning the rally ran on unwinding short positions rather than fresh bullish bets. The options market flipped after 361 straight days of puts pricing richer than calls, and the front of the futures curve repriced while the long end held—signs of a one-off event, not a regime change. The data comes from a joint Glassnode-Bybit with numbers through August 23, covering four crypto-native venues, excluding CME. Bitcoin’s most violent rally of its two-year drawdown wasn’t powered by fresh bullish bets. It was powered by…

In brief The Senate failed to advance the Clarity Act in a 49-50 vote, with Democrats voting as a bloc and three Republicans joining them; the breakdown sparked finger-pointing, though seven negotiating Democrats called it “a setback, but not the end.” With industry fatigue mounting, attention has shifted from Congress to regulators, with figures like the Solana Policy Institute’s Kristin Smith calling agency guidance “the more viable path forward right now.” Both agencies are moving: SEC Chair Paul Atkins tied a new tokenized-stock innovation exemption to the bill’s failure, while the CFTC issued no-action relief and sent a broader crypto…

A grocery store worker says scammers posing as Chase Bank fraud investigators drained $73,000 from his savings. The Mariano’s employee, identified as David Lipsky, transferred the money after callers claimed the FBI would arrest him if he did not move his funds into what they called a safe account, reports ABC7 Chicago. Lipsky says the first call appeared to come from Chase and warned that his account had been compromised. Says Lipsky, “They worked with the FBI, they said. If I didn’t do it, they were going to get the FBI at my house and arrest me.” He first tried…

In brief Bitcoin surged to $80,846, up 5.88% in 24 hours, after the Fed’s rate hike came paired with an unexpectedly dovish forecast. The spike has led to more than $230 million in Bitcoin short bets being liquidated, and over $445 million across the entire crypto market. Technical indicators suggest a bigger move could still be building. Risk assets caught a break this week that few were positioned for. The Federal Reserve raised interest rates by 25 basis points on Wednesday, its first hike since 2023, but the accompanying “dot plot” projected a median policy rate of just 4.1% through…

In brief XRP jumped 6.93% on the day, opening at $1.2964 and topping out at $1.4028 before settling near $1.3863—one of its sharpest single-day moves in weeks. The gap between XRP’s 50-day and 200-day EMAs on the daily chart has narrowed to its tightest point since August 2024, and a golden cross could form as soon as mid-October if the current pace holds. That same crossover already happened on the noisier 4-hour chart back on August 21—but the gap has been closing instead of widening since then, a warning sign the daily golden cross isn’t a lock. Crypto traders are…
