Abstract

Cryptocurrency, after years of being perceived primarily as a speculative asset or a complex technological curiosity, is finally finding its true purpose: not as money for humans, but as money for machines. While cryptocurrencies like Bitcoin and Ethereum failed to become practical daily payment tools for people due to volatility, poor user experience, and regulatory complexities, they are perfectly suited for the emerging Agent-to-Agent (A2A) economy. In this new paradigm, AI Agents autonomously transact with each other—purchasing data, API calls, or computational resources—using crypto wallets and smart contracts. They require no customer support, handle micro-payments efficiently, and operate across borders without traditional banking hurdles. Protocols like x402 are reviving the long-dormant "402 Payment Required" HTTP status code, enabling machines to negotiate and pay for services seamlessly within milliseconds. We are witnessing a fundamental shift: machines will use cryptocurrency as a high-frequency, efficient medium of exchange in the background, while humans continue to use traditional fiat currency for daily life. Cryptocurrency isn’t replacing the bank account; it’s becoming the silent, foundational layer of a new machine-driven economy.

Author: Zhou Hang

Over the past decade, if you mentioned "cryptocurrency" to an average person, the words that likely came to their mind were: getting rich quick, pump and dump schemes, hackers, or some incomprehensible geek toy.

From the emergence of Bitcoin (BTC) to the smart contract revolution of Ethereum (ETH), to the noise of various public chains and stablecoins, this world has been noisy for over a decade. Countless brilliant minds and massive amounts of capital have flooded in, trying to build a decentralized utopia.

But we still feel confused in real life: besides being a highly volatile speculative asset, besides buying low and selling high on exchanges, what is cryptocurrency actually useful for? When we go downstairs to buy a cup of coffee, we still scan WeChat Pay or Alipay; for international transfers, we still go through cumbersome bank wire processes.

It claims to颠覆finance, yet it似乎can't even handle the most basic "payment" properly.

Until today, with the arrival of the A2A (Agent to Agent) intelligent economy, this confusion finally has an answer: cryptocurrency did not fail; it just spent the past decade targeting the wrong users.

Why Cryptocurrency Couldn't Become "Human Money"

When Satoshi Nakamoto released the Bitcoin whitepaper in 2008, the title prominently read: "A Peer-to-Peer Electronic Cash System." His original intention was to create an everyday payment tool.

In 2010, a programmer named Laszlo bought two pizzas with 10,000 Bitcoins. This was seen as the great beginning of cryptocurrency payments. But the subsequent script went in another extreme direction.

There are three insurmountable practical obstacles why cryptocurrency cannot become money for daily human use:

First is volatility. When something is worth $1 today, might drop to $0.5 tomorrow, or rise to $2, no one dares to price things in it. There's an economic常识called "Gresham's Law" (good money is hoarded); when you expect Bitcoin to rise, you absolutely舍不得use it to buy pizza.

Second is the anti-human experience. Humans are creatures who极度dislike hassle. Crypto payments require you to妥善保管a long string of私钥like gibberish; once lost, assets are instantly zeroed out, with no customer service to help you recover them. You also need to understand what Gas fees are and endure long waits during network congestion.

Finally, regulation and taxes. In many countries, buying a coffee with cryptocurrency is considered an "asset sale" by the tax authority, for which you need to calculate and declare capital gains tax.

Humans need stable, simple financial services with customer service backup and legal protection. The traditional banking and fiat system, while having friction, perfectly meets human needs for security.

Cryptocurrency tried to pull humans into a cold, absolutely rational, self-risk code world, and was naturally rejected by humans, eventually morphing into a form of "digital gold" and speculative chip.

Machine Money: When Agents Become Consumers

But what if we shift our perspective from "human" to "machine"?

In the A2A intelligent economy, hundreds of millions of AI Agents will be calling APIs, buying computing power, acquiring data, and even negotiating rental contracts for you in the background every day. The CEO of Coinbase pointedly noted: "AI can't take an ID card to open a bank account, but they can control a crypto wallet without any障碍."

For AI Agents, the advantages of the traditional financial system are all disadvantages, and the disadvantages of cryptocurrency are all advantages.

Machines don't need customer service; they only trust code. Traditional contracts require lawyers to draft, courts to enforce, and banks to settle, taking days or even months. In the Agent world, they use "smart contracts"—this is essentially a program stored on the blockchain. When conditions are met, funds are automatically transferred instantly, with no possibility of违约. This is the true "machine-native contract."

Machines need millisecond-level micro-payments. Imagine an AI Agent is generating a report for you; it needs to buy a piece of real-time data from another Agent for $0.001. The per-transaction fee for traditional credit card networks is as high as $0.30,根本无法supporting such micro-transactions. Through加密networks, an Agent can complete extremely low-cost settlement in hundreds of milliseconds.

Machines have no borders and no identity. They don't need complex KYC (Know Your Customer) verification. As long as they have a private key, an Agent running on a server in Singapore can instantly pay an Agent running in Tokyo.

A Status Code That Slept for 30 Years

The最能embody this paradigm shift is a真实history full of metaphor in the internet world.

If you often surf the internet, you must have encountered "404 Not Found." In the initial design of the HTTP protocol, there was actually another status code called 402 Payment Required.

The pioneers of the internet foresaw that the future network would not only need to transmit information but also value. But because there was a lack of a native internet payment layer at the time, this 402 status code was硬生生shelved for 30 years, almost never truly used.

Until 2025, a payment protocol designed specifically for AI Agents was born, its name is x402.

Through the x402 protocol, when an Agent requests data from another server, if payment is required, the server no longer pops up a credit card form for humans to fill out, but directly returns a machine-readable "402 Payment Required" instruction. After receiving the instruction, the Agent instantly calls USDC (a dollar-pegged stablecoin) from its crypto wallet to complete the payment. The entire process ends in hundreds of milliseconds, and the data channel opens.

No registration, no scanning, no password verification. Value flows seamlessly at the bottom layer of the internet, just like data.

Human Money and Machine Money: The Folding of Wealth

According to data from blockchain analytics firms, in the short few months from late 2025 to early 2026, AI Agents have already completed hundreds of millions of payments via stablecoins. Cryptocurrency no longer needs to prove itself more useful than Alipay; it has sunk into the deep sea of the internet, becoming the silently运转blood of millions of machines.

But the story doesn't end here. When machines start to have wallets, start to earn and spend money autonomously, as humans deeply固化by the concepts of "cash" and "bank accounts," how should we understand this new form of wealth? What is the relationship between our money and the machine's money?

In the past, wealth was显性的, physical. You took out a banknote, or opened a banking App watching the balance数字change, you had a切肤之感of "spending money."

But in the future, wealth will be folded.

Imagine you hire an AI Agent to operate a social media account for you. You don't need to pay it a salary; you just need to initially top up its "Agentic Wallet" with 100 USDC (equivalent to $100).

Next, this Agent begins its autonomous狂奔: it pays another data Agent 0.05 USDC to get hot trends; pays a drawing Agent 0.1 USDC to generate an illustration; after the article is published, it automatically deposits the advertising revenue it earned (maybe 0.5 USDC) into its own wallet.

In this process, the machine's money疯狂流转, earns interest, and is consumed at millisecond speed in the underlying network. And you, as the human owner,根本看不到these密密麻麻micro-payment bills. You don't need to understand what x402 is, or what smart contracts are.

The only thing you see is a极简report this Agent sends you weekly: "This week投入$10, net profit $50, profits have been withdrawn to your fiat bank account."

This is the ultimate division of labor between humans and machines regarding wealth: Machines handle friction, humans enjoy the results.

Machine money (cryptocurrency) is for flowing,它是high-frequency, cold, production material pursuing极致efficiency;而human money (fiat) is for feeling, it is for buying coffee, paying rent,承载life security—the final destination.

Cryptocurrency did not eliminate bank accounts; it just pushed complex financial transactions one layer down. While humans enjoy the极致convenience brought by AI on the front end, in those unseen底层, a financial system专属to machines is silently重塑the business rules of this world.

Deconstructing the U.S. Stock Quantum Computing Sector: IonQ, Rigetti, D-Wave, Which of These Concept Stocks is Worth Betting On?

**Title:** Analyzing the US Quantum Computing Race: IonQ, Rigetti, D-Wave – Which Concept Stock is Worth Betting On? **Summary:** The podcast discusses the resurgence of quantum computing as a national priority for both the US and China, driven by its potential to break current encryption, revolutionize drug discovery, finance, and logistics. The core challenge is commercializing the technology, which is hampered by high error rates in quantum bits (qubits). Quantum error correction, requiring thousands of physical qubits per reliable logical qubit, is key but years away. The analysis compares three main publicly traded US quantum computing firms: * **IonQ (Ion Trap):** Considered the most financially stable with the fastest commercial progress (2025 revenue: $130M, +202%) and high-quality clients. Its valuation is very high, pricing in significant future growth. * **Rigetti (Superconducting):** Seen as the highest-risk, highest-potential-reward bet. It has the smallest revenue but recently launched a 108-qubit system. Its valuation multiples are extreme, making it highly sensitive to news. * **D-Wave (Quantum Annealing):** Has the most unique positioning with real-world enterprise clients today (e.g., Mastercard, Volkswagen) solving optimization problems. Its recent acquisition moves it into general-purpose quantum computing ("dual-platform"), adding execution risk. Major tech giants like Google, IBM, and Microsoft are also heavily invested, pursuing various technical approaches. Nvidia is positioning itself as the essential bridge between classical and quantum computing. The investment phase is likened to AI in 2018-2020: promising underlying technology with accelerating breakthroughs but a commercial inflection point still 3-7 years away, suggesting potential for a market correction ("bubble washout"). For investors, suggested approaches include gaining exposure through tech giants with quantum divisions (e.g., Google, IBM) or using niche ETFs like WQTM for pure-play quantum exposure, rather than direct stock picks in the highly volatile pure-play companies at this early stage.

Ethereum Bears In Pole Position: $1,850 Could Be The Next Landing Spot

Ethereum's price remained bearish in May, with analysts predicting a potential drop to around $1,850. Crypto analyst Burak Kesmeci notes that ETH is trapped in a descending channel on the 4-hour chart, indicating seller dominance. If it fails to break the $2,033 resistance, a decline to the $1,822-$1,850 range is likely. While a breakout above $2,033 could target $2,400, the downward move appears more probable. This bearish outlook is reinforced by significant outflows from spot Ethereum ETFs, totaling over $241 million in the past week—the third consecutive week of major outflows. ETH has lost nearly 15% of its value over the last three weeks and is currently trading around $2,023.

From Parallel Finance to Mainstream Finance: The On-Chain Securities Era Ushers in a Historic Window

From Parallel Finance to Mainstream: The Dawn of On-Chain Securities For over a decade, the crypto industry has operated as a parallel financial system with its own currencies, markets, and assets—from Bitcoin and ICOs to DeFi, NFTs, and memecoins. Despite building a robust internal ecosystem, a wall has separated it from the traditional financial world. That barrier is now crumbling. The industry's first act was one of internal evolution: ICOs streamlined fundraising, DeFi recreated financial services on-chain, and layer-2 networks competed for scalability—all within the crypto bubble. While innovative, this cycle remained closed, with capital and users circulating internally, leading to volatile boom-bust cycles. Even Bitcoin ETFs, while attracting Wall Street capital, merely provided a channel to buy crypto assets without bridging the systems. The next, larger narrative is Real-World Assets (RWA) moving on-chain. This involves tokenizing stocks, bonds, funds, and future cash flows. Blockchain can compress the complex traditional processes of trading, settlement, clearing, and custody into a seamless, automated network operating in seconds. This shift is creating a new financial gateway: the native crypto securities broker. This entity will combine functions of an exchange, broker, bank, and custodian into a unified global financial operating system. Consequently, the next major battleground won't be the "public chain wars" focused on speed and cost, but the competition to build the financial infrastructure capable of hosting high-quality, liquid real-world assets. Access to global equities, index funds, or stakes in companies like SpaceX could erase the boundary between crypto and traditional finance, unlocking a market orders of magnitude larger than crypto's current valuation. In summary, after years of creating a separate financial world, crypto's next decade will be defined by its integration into the existing global financial system, marking the true beginning of its largest growth story.

Wang Chuan: When the Neighbor Old Wang Made 30x on Memory Stocks, How to Avoid Anxiety (Part Six) - The Trap of Commoditized Goods

Wang Chuan: When the Neighbor Lao Wang Made 30x on Storage Stocks, How to Stay Anxiety-Free (Part 6) - The Trap of Commoditized Goods. This essay uses historical and current examples to analyze the cyclical and high-risk nature of the data storage industry. It begins with the 1990s rise and dramatic fall of Iomega, whose stock soared over 160x in 18 months before collapsing 97% from its peak, illustrating the fleeting success of storage "meme stocks." The core problem is that storage products, like DRAM and flash memory, are highly commoditized. This leads to extreme volatility: prices have plummeted over 80% multiple times, and company stocks often crash 95% or go bankrupt. The industry's dynamic is defined by "elastic demand facing heavy-asset, long-cycle, rigid supply." When demand spikes and supply is fixed, prices skyrocket, as seen recently with AI-driven demand for High Bandwidth Memory (HBM). Companies like Sandisk and Micron have reported massive revenue and gross margin jumps (e.g., Sandisk's gross margin rising from 22.5% to 78.3%) despite minimal increases in production volume. However, these high margins are self-defeating. They incentivize massive new capacity investments (hundreds of billions planned from 2026), with supply expected to surge by late 2027. Once new supply meets demand, prices and profits will crash, potentially leading to a scenario where "selling more results in earning less." The article debunks the safety of long-term supply agreements, comparing them to fragile non-aggression pacts easily broken when market conditions shift. It warns that when an industry is highly profitable but trades at low P/E ratios, the risk is greatest, as plummeting prices quickly erase those earnings. Multiple asymmetric risks loom, including economic recession, reduced AI spending, faster-than-expected capacity expansion (especially from Chinese firms), and technological innovations that reduce memory requirements. In conclusion, the storage sector is a cyclical trap where periods of euphoric profits are often precursors to devastating downturns, luring unprepared investors into a "wealth incinerator."

Wang Chuan: When the neighbor Lao Wang earned thirty times from investing in memory storage stocks, how can you still avoid anxiety (6) - The trap of homogeneous products

The article, "Wang Chuan: How to Remain Unanxious After Neighbor Lao Wang's Thirty-Fold Gain on Storage Stocks (Part 6) - The Trap of Commoditized Goods," analyzes the cyclical and perilous nature of the data storage industry through historical and current case studies. It begins with the example of Iomega, whose Zip drives led to a stock surge of over 160x in the mid-1990s before collapsing over 97% from its peak due to competition from cheaper CD-R technology. This pattern is characteristic of storage, where products like DRAM are highly commoditized, leading to extreme price volatility. The sector has seen prices crash over 80% multiple times, with companies often facing bankruptcy. The core dynamic is "elastic demand facing heavy-asset, long-cycle, rigid supply." High prices attract new capacity, but the long lead time means supply eventually overshoots, causing sharp price corrections. The current AI-driven boom, exemplified by surging demand for High-Bandwidth Memory (HBM), has led to skyrocketing prices and profit margins for companies like SanDisk and Micron, despite relatively flat production volumes. However, the author warns this high-margin environment is self-defeating. The high profits are already triggering massive new capacity investments (hundreds of billions starting 2026), with supply expected to ramp up by late 2027. When supply catches up, total revenue and profits may fall even as more units are sold. Long-term supply agreements offer little protection, as buyers can find ways to renegotiate if market prices drop, similar to fragile political treaties. Key risks include economic downturns, cuts in AI spending, faster-than-expected capacity expansion (especially from Chinese firms), and innovations in chip/algorithm design that reduce memory needs. A critical trap is that at the cycle's peak, storage stocks often appear cheap with low P/E ratios, luring value investors just before an impending downturn where profits evaporate. The conclusion cautions that for commoditized goods like storage, high margins inevitably destroy themselves, and the current asymmetry favors downside risk over further upside. The neighbor's dream of easy wealth from storage stocks is portrayed as a precarious illusion.
