Crypto Mayhem: Bitcoin & Ethereum Dive as Global Regulators, DeFi Hacks and Bullish Prophets Shake Up Markets (Sept 27–28, 2025)

28 September 2025
  • Bitcoin & Ethereum weakness: The crypto market saw a sharp selloff in late Sep 2025, wiping out over $160 billion in value. Bitcoin slid below $111K (off its $124K Aug peak), trading near ~$109K [1]. Ether fell under $4K, briefly dipping to ~$3,850 before rebounding to ~$4,036 [2] [3]. Altcoins tumbled as well: Cardano ~–8.5%, Dogecoin/Shiba Inu down 4–12% [4], while XRP and Avalanche showed relative resilience. The overall market cap contracted to ~$3.8T [5] [6] amid slackening trading volumes and mounting fear.
  • Driving factors: A confluence of macro trends fueled the downturn. A strong U.S. dollar (on geopolitical jitters and soft jobs data) drove investors to safe assets [7]. The U.S. Federal Reserve’s cautious outlook (Powell’s comments on labor/inflation) shook tech stocks and spilled into crypto [8]. At the same time, huge leveraged liquidations (over $1.65B in long positions [9], including ~$112M on Solana) forced forced selling in BTC, ETH and many altcoins. In short, “Red September” hit crypto hard, though some experts still foresee a late-2025 recovery [10] [11].
  • Regulatory climate: Politics and policy headlines are roiling crypto. In Washington, a potential US government shutdown (looming Sept 30 budget deadline) threatens to stall crypto rulemaking [12]. Jessica Martinez of the Blockchain Association warned a shutdown “would stall critical progress on crypto policy” [13] (though leaders reportedly remain “committed” to passing market structure and stablecoin bills [14]). On the global stage, the UK and US announced a transatlantic taskforce on Sept. 22 to align digital asset rules [15]. Elliptic policy head Mark Aruliah said this coordinated push “signals a strong intent to close [the regulatory] gap” and could set a global benchmark [16].
  • Stablecoins & finance: Regulatory news buoyed stablecoin markets. The CFTC is moving to allow stablecoins as collateral in derivatives, with acting Chair Caroline Pham dubbing stablecoins’ collateral role a “killer app” [17]. Firms like Circle, Ripple and Tether cheered the plan as a boon for liquidity. In Europe, major banks (ING, UniCredit, etc.) unveiled plans to issue a Euro-denominated stablecoin under MiCAR rules (targeting late 2026 launch) [18]. This underscores how stablecoins are being woven into mainstream finance.
  • Market metrics & on-chain data: On-chain data reflect cautious markets. Crypto futures open interest remains high (~$78B in BTC futures) even as prices drift【34†】. For example, CoinGlass data show BTC futures OI recently jumped alongside price, indicating big positions still in play. Total value locked (TVL) in DeFi stabilized around $150B [19] after recent swings. TradingView charts show Bitcoin dominance ~58–67%, hinting at renewed interest in altcoins. Notably, Solana’s network activity is softening – active addresses are down 28% in a week and network fees fell 15% [20] – as new competitors (e.g. Aster DEX) and macro fear have weighed on SOL.
  • Technology & protocol updates: Blockchain development is moving ahead despite the turmoil. Ethereum’s Fusaka upgrade is on track for a December 3 mainnet launch [21]. Vitalik Buterin highlighted that Fusaka’s new Peer Data Availability Sampling (PeerDAS) mechanism – an “unprecedented” approach allowing nodes to verify block data by sampling – will greatly boost scaling (dropping gas fees towards $0.10) [22] [23]. Gate.io launched “Gate Layer,” a new EVM-compatible Layer-2 (built on OP Stack) to scale its ecosystem (5,700 TPS, GT token burns) [24]. Meanwhile, staking-focused initiatives advance: Solana staking ETF proposals (Franklin Templeton, Fidelity, Grayscale, etc.) were amended Sept 25, and analyst Nate Geraci expects these to clear the SEC by mid-October [25].

  • DeFi & institutional moves: DeFi remains dynamic but also exposed. The upstart Hyperliquid network suffered major losses: ~$700K was drained from a Treasury Market pool, and its HyperVault protocol was rug-pulled for ~$3.6M (assets laundered via Tornado Cash) [26] [27]. Security experts warn Hyperliquid’s small validator set (4 nodes) leaves it vulnerable [28]. On the upside, companies continue to build crypto treasuries: Australia’s Fitell Corp announced a $100M convertible note to back a “Solana treasury strategy” aimed at generating yield from SOL [29]. Bitcoin ETF volumes (e.g. BlackRock, Vanguard) are still strong; MicroStrategy CEO Michael Saylor forecasts new Bitcoin highs by year-end, noting that “companies and ETFs are buying far more Bitcoin than the miners produce,” creating an ongoing supply squeeze [30] [31]. Over $6B is now held in corporate treasuries across 200+ companies, attracting regulatory scrutiny (SEC/FINRA are probing firms for suspicious stock moves around crypto announcements [32]).
  • NFTs & Metaverse: Interest in digital worlds is rebounding. According to DappRadar/Coindesk, metaverse-related NFT sales jumped 27% in August (13,927 items sold, ~$6.5M volume) [33]. Analyst Sara Gherghelas noted the metaverse “is far from obsolete, with users gradually returning” [34]. Platform updates abound: Sandbox held a record LAND auction, Otherside (Yuga Labs) added AI world-building tools, Decentraland rolled out a major graphics engine upgrade, and Mocaverse is gearing up its own Moca Chain (testnet soon) [35]. Binance also reported a slight uptick in NFT trading volume overall, driven largely by gaming and meme projects. Meanwhile, Web3 gaming remains vibrant, with new “play-to-earn” titles launching globally (the Filipino game GIGACHADBAT debuted its baseball-themed NFT project recently).

  • Security alerts & scams: Law enforcement and hacks made headlines. Interpol led a global crackdown (“Operation HAECHI VI”), seizing $97M in crypto and 68,000 bank accounts from online fraudsters [36]. In DeFi, the Hyperliquid exploits (above) underscore ongoing risks in novel protocols [37] [38]. Crypto.com vigorously denied reports that it hid a 2023 data breach; CEO Kris Marszalek called the Bloomberg/X account story “misinformation,” noting any phishing incident was “contained within hours” and promptly reported [39]. On the NFT side, scammers continue to mimic big brands. Notably, the ubiquitous “Scattered Spider” hacker group (linked to FBI indictment) claimed responsibility for a Phishing attack at BloomTech, though no large exchange breaches were confirmed beyond Crypto.com’s admitted minor incident. Finally, market analysts flagged an uptick in Rug-pull accusations (e.g. the now-defunct HyperVault and various token launches) – a reminder that due diligence is crucial as DeFi TVL grows (already ~$150B).
  • Expert commentary: Voices across crypto weighed in. Galaxy Digital CEO Mike Novogratz told Bloomberg that recent U.S. bills (the GENIUS Act and CLARITY Act) will “unleash a tremendous amount of new participation in crypto,” potentially upending the old four-year cycle [40]. He also noted that bearish news (including Hyperliquid’s woes) contributed to the pullback, but he believes “this is just a pullback” and expects the bull market to resume [41]. Crypto “mom” Commissioner Hester Peirce (SEC) again joked about moving on (her beekeeping quip) but reaffirmed she favors balanced regs that don’t stifle innovation. SBI Asia CEO Yuji Nishi (former SEC official) commented that Asian regulators are still in “wait and see” mode on ETFs and crypto IPOs, eyeing U.S. guidance. On policy, Blockchain Association’s Jessica Martinez warned lawmakers that “a shutdown would stall critical progress on crypto policy,” while Solana Policy Institute’s Kristin Smith agreed it would be “a setback, but it’s clear [Congress] remain committed” to passing a market-structure bill [42] [43]. In markets, Elliptic’s Mark Aruliah said the UK–US taskforce “will strengthen a shared commitment to higher standards” in crypto oversight [44]. Samsung’s influential blockchain exec, Jaemin Won (Galaxy Security), reiterated that “security-first design” is vital after Hyperliquid, echoing calls for more audits and insurance in DeFi.
  • Outlook & upcoming events: Heading into September’s end, focus shifts to several key dates. On Sept 29, the SEC and CFTC will hold a joint roundtable on digital asset regulation, expected to clarify cross-border and collateral questions [45]. In Congress, House and Senate leaders aim to mark up the crypto market-structure bill (CLARITY) in Oct/Nov (per Rep. Hill). Onchain, Ethereum’s Fusaka is tentatively scheduled for Dec. 3 (the current $2M audit contest has dozens of findings to fix) [46]. Meanwhile, crypto conferences and elections loom: Europe’s MiCAR stablecoin framework takes effect in Jan 2026 (spurring the euro-coin push [47]), and Brazil’s DAC 2025 this week brought together BlackRock, CME, Tether and regulators to debate Latin America’s crypto path. Macro-watchers will monitor U.S. inflation/labor reports and Fed moves, plus China’s stance: Beijing just instructed Hong Kong to pause some real-world asset (RWA) token projects [48].

  • TTD vs ROKU: Should Investors Buy The Trade Desk Stock Instead of Roku?
    October 19, 2025, 6:54 AM EDT. Investors debating whether to buy The Trade Desk (TTD) or Roku (ROKU) will note both stand to gain from the ongoing streaming adoption. The piece highlights that even with different business models, both names have benefited from the secular ad-spend and user growth in connected TV. It references Stock Advisor's top-10 approach, noting that TTD wasn't among the current recommendations, while Roku and TTD carry positions for Motley Fool analysts. Past calls, such as Netflix (2004) and Nvidia (2005) recommendations, show how early picks can compound dramatically, though no guarantee exists. The article also cites historical Stock Advisor performance (average ~1,055% since inception) and points to price data from Oct 16, 2025. Investors should weigh strategic fit, risk tolerance, and timing before deciding.
  • Lyft Emerges as a Growth Driver for Portfolios Amid Strong Profitability and Cheap Valuation
    October 19, 2025, 6:52 AM EDT. Lyft is expanding at a double-digit pace, with Q2 2025 rides up 14% year over year and underpenetrated markets like Nashville posting 20%+ growth. The ride-hailing company has also turned a corner on profitability, delivering positive free cash flow on a trailing-12-month basis and six straight quarters of gains under CEO David Risher. Despite higher sales and marketing spend, core expenses remain in check and R&D declined. With a current valuation near 8x free cash flow-well below peers-Lyft offers a rare mix of top-line growth, bottom-line improvement, and an attractive valuation. The company's guidance for 13%-17% bookings growth in Q3 underscores its momentum, making it a potential staple for growth portfolios.
  • Where Will Nvidia Stock Be in 3 Years? AI Demand, Market Share Risks, and the Path Forward
    October 19, 2025, 6:36 AM EDT. Nvidia has dominated the AI GPU market and is positioned to stay ahead over the next three years. Its GPUs power the training of today's generative AI models, driving ongoing revenue and profit growth as hyperscalers push more data-center capex. The 2026 cycle could set new records in enterprise spend. But the bull case isn't without risk. AMD has signaled parity with a major OpenAI deal, suggesting potential share loss to cheaper hardware. Broadcom is pursuing custom AI accelerator chips that can beat Nvidia on cost for specific workloads, though with less flexibility. There are two main scenarios, one more likely: Nvidia maintains leadership while facing pricing pressure and some share erosion.
  • IPO Genie Launches AI-Driven Crypto Presale Aiming at $3 Trillion Private Markets
    October 19, 2025, 6:20 AM EDT. IPO Genie ($IPO) is positioning itself as the largest crypto presale by combining AI-driven insights with blockchain verification to unlock private markets access. The platform evaluates pre-IPO opportunities using AI analytics across thousands of data points, helping investors discriminate growth signals from hype. Each transaction is anchored by blockchain verification, providing auditable transparency and tamper-proof records. The project offers tokenized market access so retail investors can participate in deals historically limited to VCs and institutions. Long-term holders can benefit from staking & rewards, while its insurance-backed risk management framework aims to mitigate volatility. By bridging crypto with traditional private markets, IPO Genie targets data-informed participation rather than speculative hype, inviting early entrants to participate in a new era of accessible, AI-powered investing.
  • One Incredible Reason to Buy UPST Stock as Rates Fall
    October 19, 2025, 6:02 AM EDT. Upstart (UPST) has been volatile in 2025, down 23.5% year to date, but the stock now trades around 19x forward earnings - a compelling entry for growth buyers. The big driver: easing interest rates. As the Fed and market rates fall, borrowing costs drop, defaults ease, and Upstart's AI-driven lending platform benefits from a friendlier environment. After years of revenue decline, Upstart is back in growth mode, with Q2 revenue more than doubling YoY and transaction volume up 159%, helping return to GAAP profitability sooner than expected. With the Fed's rate-cut path continuing and Q3 guidance calling for roughly 73% revenue growth and about $9 million in net income, the stock could resume its uptrend.
