$20 for a Face: The Underground Business of Crypto KYC

Crypto KYC Bypass: A $20 Underground Industry Despite stringent KYC (Know Your Customer) requirements from major crypto exchanges, a thriving underground market exists to bypass these checks for as low as $20. Users often face geo-blocks or lengthy verifications, preventing access to services. This has fueled demand for illicit KYC services. Reports indicate over 500,000 participants in underground KYC markets, with more than 1 million listings selling verified profiles from platforms like Coinbase and Kraken. These accounts often include real personal data, sometimes without the original owners' knowledge. Fraud techniques have evolved, including deepfake attacks (up 2000% in three years), screen-based spoofing, and AI-generated fake documents. The virtual currency sector is the primary target, accounting for over 78% of KYC attacks. An investigation into a Telegram-based KYC vendor revealed a TRON address with over $59,000 in USDT from 600 transactions over two years, all eventually transferred to an OKX hot wallet. An interview with a KYC service provider, "Maoli," who operates in Chinese-speaking regions, detailed the process: clients pay for accounts verified by "foreigners" recruited globally, often from lower-income regions, who perform the KYC steps for a small fee. These accounts are sold with warnings against holding large funds due to fraud risks and potential reclaiming by the original identity owners. Maoli described the business as a "three-way win": users gain access, exchanges get user numbers, and he profits. However, this ignores the victims of identity theft whose data is used without consent. The KYC system, while intended for security, functions as a permeable barrier, with a vast shadow economy ensuring access for those willing to pay.

Ripple CEO Says XRP Utility Is Company’s ‘North Star’, Acquisitions Overperforming

Ripple CEO Brad Garlinghouse emphasized that enhancing XRP's utility is the company's core guiding principle, or "North Star," driving its product development and acquisitions. He noted that recent acquisitions, including Ripple Treasury and Ripple Prime, have significantly exceeded expectations, with Ripple Prime tripling its revenue. Garlinghouse highlighted a major opportunity in integrating crypto and stablecoin payments into traditional treasury systems, pointing out that $13 trillion in payments were processed last year with zero crypto involvement. He also discussed U.S. crypto regulation, expressing support for the CLARITY Act but revising his expected timeline for its passage to late May, stressing the importance of clear regulations to retain innovation and investment in the U.S.

US Media Reveals the Inside Story of Sora's Shutdown: Losing Millions Daily, User Base Halved, and Facing Talent Poaching from Competitors

OpenAI has abruptly shut down its Sora video-generation tool, a project once hailed as the next consumer AI frontier after ChatGPT. Initially launched with high expectations, including a major partnership with Disney, Sora allowed users to insert themselves into various video scenes. However, it quickly became a significant financial drain, reportedly losing about $1 million daily. Its user base peaked at roughly one million before halving, and it consumed excessive computational resources needed for OpenAI's core priorities, such as its upcoming "Spud" AI model and enterprise productivity tools. Facing stiff competition from rivals like Anthropic and a strategic shift towards AI agents and coding tools ahead of its IPO, OpenAI decided to reallocate resources. Key researchers behind Sora were also targeted in a Silicon Valley talent war, with Meta's CEO personally attempting to recruit them. The shutdown shocked Disney, which had planned to invest $1 billion and use Sora across its operations. The deal has now collapsed, and Disney is exploring other AI partnerships. OpenAI will focus its efforts on robotics and other long-term projects.

Memory Module Prices Plummet, Memory Stocks Fall Collectively, Has the Memory Super Cycle Peaked?

Memory module prices have plummeted recently, with DDR5 kits in the U.S. seeing discounts of up to $110 and wholesale prices in China dropping sharply. This has triggered a significant sell-off in memory stocks, wiping nearly $100 billion from the sector's market value last week. Analysts are divided on whether this signals the end of the memory "super cycle." Some, like Dan Nystedt, argue that buyer resistance to high prices, especially for DDR4 in smartphones, indicates a classic cyclical peak. However, others, including independent analyst Jukan, contend that the current cycle is structurally different, driven by essential, inelastic demand for high-end DDR5 in AI and premium devices, with manufacturers now operating models that prevent reckless overcapacity expansion. Investment bank HSBC remains bullish, calling the recent sell-off an overreaction and stating that the AI-driven super cycle is only at its midpoint. It argues that efficiency technologies like Google's TurboQuant will accelerate, not hinder, AI adoption and demand, and it forecasts strong growth in AI server shipments and enterprise SSD demand through 2027. It views any price pullback as a buying opportunity.

SIREN sings a warning even as bulls defend local support: What’s next?

AI-powered memecoin SIREN has exhibited significant volatility and bullish momentum since February, though it recently entered a corrective phase. The 3-day chart remains in a bullish trend, but the RSI is retreating from overbought levels, and trading volume has notably declined. A descending triangle pattern suggests a potential breakdown below the critical $0.78-$0.80 local support zone. If breached, this could trigger a deeper correction toward $0.70. For a sustained upward move, a high-volume breakout above $2 is necessary, but current low demand makes this unlikely. Traders are advised to wait for clearer signals, as a false breakout or further decline appears probable in the short term.

Euro Stablecoins Have Entered DeFi, What Are Other Local Currencies Waiting For?

Euro stablecoins are leading the adoption of non-USD stablecoins in DeFi, while other local currency stablecoins remain primarily used for payments and settlements. The implementation of MiCA regulations in Europe effectively ended Tether’s EURT, reducing its supply from over $400M to around $50M. However, the broader non-USD stablecoin market (excluding EURT) has nearly tripled since early 2023, reaching $1.1B by February 2026. Euro-denominated stablecoins account for over 90% of non-USD transaction volume and are increasingly integrated into DeFi protocols like Aave and Morpho for lending and trading. In contrast, other local currency stablecoins (e.g., BRL, JPY) are mostly used for payments, remittances, and enterprise settlements, with nearly 80% of their activity falling under unidentified transfers. Regulatory clarity, as seen in Brazil and Japan, is crucial for adoption. The growth of non-USD stablecoins is driven by their potential to reduce FX costs, streamline cross-border payments, and minimize dollar dependency. While euro stablecoins have set a precedent for DeFi integration, broader adoption of other local currency tokens will likely focus first on payment infrastructure before expanding into DeFi applications.

Tiger Research: What AI Services Do Crypto Companies Offer?

This Tiger Research report examines the growing trend of cryptocurrency companies integrating AI services, driven by a fear of missing out (FOMO). Unlike previous cycles, established and profitable firms like Coinbase and Binance are leading this charge, moving AI from theory to practical necessity. Key areas of AI adoption include: - **Research:** Projects like Surf are building crypto-native AI tools that aggregate fragmented on-chain and social data, providing more accurate answers than general AI models. - **Trading:** Exchanges are deploying AI to let users execute trades via natural language commands, lowering the barrier for non-developers and automating strategies. The goal is user retention in an increasingly competitive landscape. - **Security/Audit:** Firms like CertiK use AI to enhance smart contract audits by automating initial code scans and enabling post-audit, real-time monitoring, thus addressing previous security blind spots. - **Payment Infrastructure:** Protocols are emerging to enable AI agents to make autonomous payments (e.g., for APIs or services) using on-chain wallets and stablecoins. Circle’s proposed Gateway-x402 integration is a notable example, though this field is still nascent. The push is fueled by rapid AI advancements (e.g., MCP, OpenClaw) and competitive anxiety. However, the report cautions that while adoption is accelerating, the gap between offering a feature and its actual, trusted use remains significant. The motivation is strategic positioning for an AI-driven future, not just marketing.

How to Determine if a Candlestick Chart is Worth Buying in 3 Seconds

In his article, experienced crypto trader Mac shares a simplified approach to quickly evaluating whether a chart is worth buying within 3 seconds, based on market structure rather than complex indicators. He emphasizes four key rules: buy if the chart is in an uptrend (making higher highs and higher lows), avoid if it's consolidating or in a downtrend (making lower lows and lower highs), and consider buying if it's transitioning from a downtrend to an uptrend. Mac explains that market structure breaks—such as a price falling below a previous higher low in an uptrend or breaking above a previous lower high in a downtrend—signal trend changes. He uses examples like PayPal, Coinbase, and Bitcoin to illustrate these concepts, showing how structural breaks indicate shifts in market control between buyers and sellers. He also shares three critical lessons: avoid trying to "catch the bottom" in a confirmed downtrend, trust your analysis by combining technicals with fundamentals and narrative, and don't worry about entering late—just not too late, ideally after a few higher highs and higher lows confirm the trend. The goal is to improve trading odds by focusing on clear, high-timeframe trends and avoiding emotional decisions.
