The article not only covers strategy application and risk control points but also provides a comprehensive analysis of industry controversies and risks.

Dive into Polymarket’s explosive growth in 2025 and explore how it leverages blockchain-based prediction markets, regulatory adaptation, and user-driven innovation to reshape the landscape of information trading and speculation—while uncovering early investment opportunities in the new market cycle.

In Q3 2025, the NFT market posted $1.58 billion in trading volume across 18.1 million sales transactions. With speculative activity waning and infrastructure development surging, utility-driven assets have emerged as the primary growth engine.

As speculative sentiment declines in 2025, a distinct group of winners remains in the crypto market. Rather than trading coins or chasing market trends, these individuals consistently earn stable returns through arbitrage. This article, based on in-depth interviews with four arbitrage professionals, reveals the evolution of their strategies: from manual trading-based arbitrage to high-frequency quantitative trading, and from airdrop harvesting to cross-chain arbitrage. Their experiences demonstrate a more measured and pragmatic approach to achieving sustained success in the cryptocurrency industry.

The article notes that while the x402 protocol is currently gaining significant adoption, the ERC-8004 standard—its complement and potentially more impactful counterpart—is emerging. It analyzes the relationship between the two protocols: x402 addresses payment challenges for AI Agents, while ERC-8004 focuses on Agent identity, reputation, and verification. The article indicates that ERC-8004 may represent a foundational infrastructure opportunity for the next phase of the Agent Economy.

This article provides an in-depth analysis of how stablecoin systems are quietly becoming "narrow banks" within the financial landscape. Stablecoins absorb substantial fiat-pegged assets backed by U.S. Treasury bonds, and in doing so, they siphon capital from the traditional banking sector. The author describes this as a "liquidity black hole," emphasizing that the rapid growth of stablecoins could undermine banks’ credit creation processes and disrupt monetary policy transmission. This development introduces novel systemic risks that are transnational and blockchain-based, moving beyond conventional finance.

This report highlights that as of August 2025, the global stablecoin market capitalization has reached $280 billion, with annual on-chain settlement volumes surpassing $30 trillion. Stablecoins are evolving from mere crypto trading instruments into global financial infrastructure. This explosive growth is driven by regulatory implementation and the entry of major enterprises. The enactment of the GENIUS Act, the Stablecoin Bill, and the MiCA Regulation mark the beginning of a “compliance grand era” for stablecoins. Their model has advanced into a “Peg + Yield + Application” triad, expanding across payments, yield generation, and real-world applications. At the same time, competition has shifted from “token battles” to “infrastructure battles,” with players such as Tether, Circle, Stripe, and Alchemy Pay building proprietary blockchains to capture dominance in payments and settlements.

This article systematically outlines three core trading categories that traders must master in 2025: incremental, convex, and specialized trading. The author provides an in-depth analysis of their respective risk-return structures, success probabilities, and occurrence frequencies, revealing a complete strategic spectrum ranging from steady compounding to high-risk breakthroughs. Whether you're a short-term operator or a long-term trend trader, this classification framework can help you identify your trading style while optimizing strategies and risk management.

The article proposes a novel perspective: the crypto world is actually divided into two systems - "narrative-driven" and "utility-driven." The former is propelled by stories and visions, such as Bitcoin, AI x Crypto, and x402; while the latter centers around real-world use cases and yields, like stablecoins, wallets, and exchanges. The author provides an in-depth analysis of the logic and interaction between these two systems, offering builders and traders a framework for making trade-offs and identifying arbitrage opportunities between narratives and practical applications.

This article provides a systematic review of the x402 protocol’s ecosystem changes in the week following the explosive popularity of $PING, analyzing why it did not become a short-lived phenomenon. It highlights that x402’s sustained momentum is driven by support from Coinbase, a distinctive narrative that integrates AI with payment scenarios, and a capital migration trend from meme tokens to real-world applications. Proactive expansion across multiple chains has also established a solid foundation for x402’s long-term growth.

The article also presents several innovative use cases, such as gas-free user experiences, the x402 browser, and on-chain marketplaces. These concepts not only demonstrate strong foresight and inspiration but also offer valuable references for developers and professionals in related fields.
