1,404 个钱包被清空，130 万美元的 QU 被转走，Qubic 团队做的第一件事是把网络暂停。

停机止血在安全事件里算标准动作，但放在一条主打“去中心化”的链上就很刺眼：能一键暂停的网络，和银行冻结账户的区别，只在于谁按那个按钮。

Qubic 不是无名项目，它一直把“有用的工作量证明”和 AI 训练挂在嘴边。可这次被盗的细节——漏洞在哪、攻击者还动了什么——官方还没给完整说法。对持币人来说，最难受的不是这次亏了多少，而是不知道下次还会不会有。

更现实的是善后。1,404 个地址，平均每个损失不到 1,000 美元——对大户是小数，对普通用户可能是一个月工资。链上不会退款，团队会不会自掏腰包补，才是这类项目真正的信用测试。这类事件的赔付通常拖很久，最后往往是基金会出一部分、社区投票认一部分，散户能拿回几成要看运气。

我不觉得“暂停”本身是错。事发时先把漏洞堵住，比硬撑着讲去中心化更负责。但如果每次出事都靠一个中心化开关，这条链的叙事就得重写。所以我现在看新公链，会先问一句：出事的时候，谁能按下暂停键？

你站哪边：停机止血是负责任的止损，还是一条能随时暂停的链根本不配叫去中心化？

For $2,500, you can now buy Grayscale’s crypto-themed funds. Products like these used to be largely available only to accredited investors. Now Grayscale has teamed up with Republic to slash the minimum to the price of a phone—sounds like a real push into the retail market.

This launch includes three funds focused on DeFi and AI, with assets like UNI and TAO among their holdings. It makes sense when you look at Grayscale’s position: spot ETFs are locked in a fee war, making it harder to charge high fees on traditional products. So it’s bypassing ETFs and shifting to “themes + retail distribution.” What it’s selling isn’t crypto—it’s a packaged narrative.
👉 关注我，点击进入聊天室，学习更多策略
But these two types of products are nothing alike. ETFs can be bought and sold on an exchange at any time, and their fees are clear at a glance. These funds typically have lockup periods, higher fees, and slower NAV updates. They also lack a secondary market, so if you want to sell, you can only redeem according to the fund’s rules. When markets move fast, that difference can matter more than the fees. $2,500 buys you access to an investment—not liquidity. Those two words rarely appear in bold on sales pages.

So I wouldn’t call this financial inclusion. It’s more like breaking a complex product into smaller pieces to sell. A lower minimum doesn’t mean lower risk. It’s really suited to people who can handle lockups and volatility. Those who aren’t suited to it may mistakenly think they can afford the risk just because the minimum is low. Before you buy, ask yourself: Can I lock this money up for six months?

Which side are you on: Is this giving ordinary people access to private-market-style investments, or pushing small investors toward products they shouldn’t touch?
#灰度联合republic推出三只加密基金

7,800 coins, worth about $640 million at current prices—the national wallet of El Salvador has crossed another round-number milestone.

That figure is actually small in market terms: less than the net inflows to exchanges over the past week, and not enough to fuel any meaningful rally. But it was built up coin by coin over several years using public funds, by a sovereign nation that kept buying despite a steady chorus of naysayers.
👉 关注我，点击进入聊天室，学习更多策略
I’ve always thought the interesting part isn’t “how much it’s made,” but that it has tied the country’s creditworthiness to a highly volatile asset. It has no hedging tools, and it can’t issue bonds to buy back shares like a company. It can only ride it out—and there’s no exit clause in this experiment. When prices rise, it’s an achievement; when they fall, it’s a hole in the public finances. Supporters say it’s a first move to hedge against dollar hegemony; critics say it’s a concentrated bet made with public funds.

By comparison, 7,800 coins are about the size of the treasury holdings of a mid-sized publicly listed company—nowhere near enough to “change supply and demand.” To the market, it’s a sentiment indicator; to this country, it’s a real line item on the balance sheet. So it’s more like a public experiment: if even a sovereign nation can withstand a deep drawdown, other small countries will have a blueprint; if it can’t, it will be a cautionary tale.

The market is watching not because it’s big, but because it’s bold. Interestingly, at the same time, coins are flowing into exchanges—with net inflows of 8,000 over seven days—while the country is moving them out. Two groups of people are doing the exact opposite.

Which side are you on: is this a model for how small countries can turn things around through sovereign adoption, or a long-term concentrated bet that hasn’t reached settlement day yet?
#萨尔瓦多比特币持仓突破7800枚

DeepSeek just updated V4.1-Flash-1017, scoring 77.0 on DeepSWE at one-tenth the per-task cost of its U.S. peers.

Most people skimmed it as another AI headline. I’m focused on a different detail: it beat much larger rivals on agentic tasks. In crypto terms, if an agent is going to monitor liquidity pools on-chain, adjust positions, and jump on liquidations for you, its reasoning costs need to drop by an order of magnitude before it can truly run 24/7—rather than making you wince every time it’s called.
👉 关注我，点击进入聊天室，学习更多策略
But the market wasn’t impressed today. TAO, FET, and RNDR were all in the red over the past 24 hours, down 1.1%, 0.8%, and 2.0%, respectively. The AI sector didn’t gain a penny just because costs fell. People are still buying the narrative, not usage. This update also introduced a Search API, letting agents look up information on their own—that’s a lot closer to being “useful” than a benchmark score.

Here’s another easily overlooked move: it ties the model more closely to its own harness, turning calls, retrieval, and execution into a single pipeline. That makes life easier for teams building agents, but it’s bad news for middlemen who make money simply by reselling API access at a markup.

My take is cautious: lower costs benefit the application layer first, but not necessarily tokens. Over the next few weeks, we should be watching real on-chain agent calls and payment data—not benchmark scores from a launch event.

Which side are you on: will AI agents generate real on-chain revenue within six months, or will this cycle still be all about speculating on coins?

The Dow rose 0.67% this week, closing at 52,002; growth stocks fell 5.49% over the same period. The gap between them was 6.2 percentage points—the widest since July 2002.

This isn’t a crash; it’s a shift in seating. The money hasn’t left the market—it’s just moved from “story stocks” to companies with cash flow. What’s really worth noting is small caps: the Russell 2000 fell 3.05% over the same period, suggesting investors are picking only the safest names, rather than broadly fleeing risk.

The fear gauge tells a similar story: the VIX closed at 19.99, up 31% for the week. Sentiment is tightening, but we haven’t reached panic-selling levels.

I think the takeaway for crypto stings a little: BTC was basically flat around 81,500 this week. It wasn’t embraced as a safe haven, nor dumped like a tech stock. Right now, it’s in a “nobody cares” position—when money rotates within U.S. stocks, it doesn’t get any marginal buying.

Which side are you on: is this a healthy rotation midway through a bull market, or the first stage of an AI bubble bursting?
#纳指道指周度差距创2002年7月来最大

In Buenos Aires, one stablecoin costs 1,600 pesos. The official rate is 1,535; the black-market rate is 1,555. That extra bit is called the “cost of escape.”

Put the three rates side by side, and the story is crystal clear: you can’t buy at the official rate, the black market means going out and standing in line, while USDT lands in your wallet with a single tap. Paying 3% to 4% more buys you the certainty that your savings “won’t be devalued overnight.” In a country with triple-digit annual inflation, that insurance premium is a bargain.

So it’s no surprise that global stablecoin payments grew 45% in a year. The real growth isn’t on Wall Street trading floors; it’s on phones in Lagos, Istanbul, and Buenos Aires. The same tool, two different lives: Americans are debating whether stablecoins should pay interest, while Argentinians are using them to protect a month’s wages.

My view is that the strongest demand for stablecoins has never been for “faster payments”—it’s for “safer savings.” That demand won’t disappear whether the Fed raises or cuts rates.

Which side are you on: Is USDT in Argentina financial infrastructure, or a tool for capital flight?
#阿根廷usdt价格突破1600比索

The Nasdaq 100 fell 5.49% this week, closing at 29,187 points—its worst week in 18 months. But the real damage was in AI: Nvidia fell 6.6% for the week, and CoreWeave dropped 25.2%.

Tom Lee said yesterday that crypto and chip stocks had both pulled back to support levels, and that a rally was “ready to take off.” I’m not so sure. Support levels only hold when liquidity isn’t a problem, and right now the problem is precisely the denominator: PPI is up 6.3% year over year, Brent crude is above $110, and interest-rate expectations are being pushed back. This isn’t a pullback caused by improving earnings; it’s a repricing of the discount rate.
👉 关注我，点击进入聊天室，学习更多策略
Crypto, by contrast, seems to be holding up: BTC is still hovering around 81,500, down much less than the Nasdaq. But don’t rush to call it “decoupling”—last time, it didn’t catch down until after stocks had fallen for three days.

My take: this week marks the first genuine valuation reset of 2026, not an ordinary pullback. For a real bottom, oil prices and inflation expectations need to stabilize first—not just hold at some particular level.

Which side are you on: do you believe Tom Lee’s claim that a rebound from support is “ready to take off,” or do you think this is the first crack in the AI bubble?
#纳指100本周跌5.5%创18个月最大周跌幅

CrossRiver has integrated RLUSD into its core banking platform. In other words, institutions that bank with CrossRiver can now hold and settle Ripple’s stablecoin directly on their ledgers, without having to build their own crypto rails.

There was another major development the same day: DTCC is preparing to advance the tokenization of 25 securities on Canton and Besu. One is on the deposits side, the other on the securities side—both are moving onto the blockchain at the same time.
👉 关注我，点击进入聊天室，学习更多策略
Looking at these two developments together, I’ve reached a conclusion that runs counter to the mainstream view: crypto isn’t replacing banks; banks are turning blockchains into their new rails. The real battleground for stablecoins has never been exchanges—it’s core ledgers. Whoever gets into the core system is the one who gets access to real settlement volume.

That’s also why I rate “bank-backed stablecoins” like RLUSD so highly: they don’t rely on offshore demand; they rely on whether banks are willing to write them into their systems. CrossRiver has now done so. The next question is how many others will follow.

Which side are you on: will bank-backed stablecoins eat into USDT’s offshore market share, or will they always be just an internal settlement tool for institutions?
#crossriver银行核心平台接入rlusd稳定币

U.S. PPI surged to 6.3% year over year. Inflation hasn’t died down at the production stage—instead, it’s accelerating again here.

Producer prices are upstream of consumer prices. A rise this sharp means it’ll be hard for CPI to come down smoothly over the next few months. More troubling, oil prices just hit $110 today. Tensions around the Strait of Hormuz are pushing up shipping, energy, and chemical costs, piling on even more pressure.
👉 关注我，点击进入聊天室，学习更多策略
But the market is pricing in a completely different story: the odds of a rate hike in October are just 17%, while the 10-year Treasury yield is 5.12%. Upstream inflation is reigniting on one side, while interest-rate expectations are confidently saying “it’s all fine” on the other. Sooner or later, one of these two will have to give.

Crypto is caught in the middle and taking the hardest hit. BTC is back around $81,500. Yesterday, spot BTC ETFs saw net outflows of $82.38 million, while ETH ETFs saw net outflows of $69.68 million. With real interest rates high and capital pulling out, valuations can only be pushed lower.

My take: if that 6.3% figure is still rising next month, then the 17% odds of a rate hike are wrong. When that happens, all long-duration assets will be hit—and crypto won’t escape.

Which side are you on: do you believe “inflation has peaked, and we can breathe easy,” or do you think this is just the beginning of a second uptick?
#美国ppi同比升至6.3%

Brent crude has touched $110 for the first time since May.

The flashpoint is the Strait of Hormuz. Iran says the strait has been closed again and has threatened to strike vessels attempting to pass through. A few hours later, reports emerged that Trump was preparing to strike Iran within 24 hours. Oil prices climbed from $106.65 to near $110, closing yesterday at $109.86.

This waterway carries about one-fifth of the world’s seaborne crude oil. When it comes under pressure, inflation expectations rise with it—Lagarde just warned today about the upside risks to inflation. Yet the market is still pricing in only a 17% chance of a rate hike in October. The two sets of expectations are completely at odds.

Crypto’s reaction is telling: BTC fell back to around $81,500, and all four spot ETF categories saw net outflows on the same day. It hasn’t become a safe-haven asset; it remains a high-beta risk exposure.

My take is that this has nothing to do with “digital gold”—it’s purely liquidity-driven pricing. If oil holds at $110, valuations will take the hit first, not the narrative.

Which side are you on: will this geopolitical conflict turn BTC into a true safe-haven asset, or will it once again prove that it’s just an amplifier of risk assets?
#布伦特原油自5月来首次触及110美元

A business with 36 trillion in transaction volume, but only 1.4 billion in revenue. Circle’s half-year report puts this mismatch front and center: a take rate of 0.004%.

The transaction volume USDC processed in half a year was enough to match the annual output of several countries, yet Circle actually pocketed just 1.4 billion.
👉 关注我，点击进入聊天室，学习更多策略
More subtle is the structure: stablecoin payment volume rose 45% this year, reaching $480 billion, while the total stablecoin supply has stagnated. The money is “moving,” not “staying.” Over the past seven days, USDC’s net supply has also fallen by about 500 million tokens. Allaire said banks “no longer control payments”—a forceful statement, but the flow of funds doesn’t back him up.

My view runs counter to the mainstream: banks aren’t being replaced; they’re absorbing stablecoins. CrossRiver has plugged RLUSD directly into its core banking system, effectively turning stablecoins into a new type of bank account. Companies like Circle don’t make their money from tolls on the payment network, either—they earn interest on reserve assets. Once interest rates fall, the true nature of this business will be laid bare.

The stablecoin payments narrative is pushing valuations up, but it can’t lift the revenue curve. Sooner or later, those two things will collide.

Which side are you on: are stablecoins really revolutionizing banking, or are banks turning stablecoins into their own new counter service?
#circle上半年营收约14亿美元

Fidelity just released a set of figures showing that the correlation between crypto’s total market cap and U.S. Treasury yields has hit an all-time high. Two things that once seemed completely unrelated are now tied together. This isn’t some tiny change in the decimals—it’s a shift in what kind of asset crypto is.

Think about it: the story we’ve been hearing for over a decade—that crypto is “digital gold” and decoupled from macro forces—is being gradually overturned. The past few days have been a perfect example. The 10-year Treasury yield climbed back above 5.12%, and as markets rushed to reprice fiscal and interest-rate expectations, crypto prices got dragged down too, falling to around $81,400. AI stocks on Wall Street also broadly declined, with CoreWeave dropping nearly 12% in a single day.
👉 关注我，点击进入聊天室，学习更多策略
I’ve always thought that what an asset is tied to matters more than how much it has gone up. Now that crypto is tied to Treasury yields, it’s influenced not just by sentiment in the crypto world, but by every bond-market data point across the ocean. The drop you see when you wake up may simply be the result of a Treasury auction that took place overnight. For someone who watches the markets all day, the change is subtle but significant: you’re no longer watching just the candlesticks, but an entire macro narrative.

Of course, there are two sides to this. The upside is that crypto has finally been incorporated into the mainstream macro pricing framework instead of remaining an island talking to itself. The downside is that it has lost its independent narrative: its ups and downs now depend on interest rates, and investors seeking safety won’t treat it as a refuge anymore.

So here’s the question: where do you stand on this growing connection? Is it a major step toward crypto being accepted by the mainstream, or the beginning of the end of its independent price action—as it becomes just another branch of risk assets?

Deutsche Bank is getting into the game. The latest news is that Germany’s largest bank plans to launch Bitcoin and Ethereum custody services within weeks, then expand the business into Asia next year. It’s a short announcement, but one worth a closer look.

“Custody” may sound unremarkable, but it carries a lot of weight. Retail investors holding a pile of coins worry less about price swings than where to keep them. When a bank takes on that role, it’s putting its century-old reputation behind crypto assets. Many European institutions managing tens or hundreds of billions are required by regulations to use licensed custodians. Until now, they could only watch from the sidelines. Now the door has opened a crack, and those who get through first can claim the early spoils.
👉 关注我，点击进入聊天室，学习更多策略
What’s interesting is that over the past two years, it’s often been banks in Europe and Asia—not the US—that have brought crypto into traditional finance. Deutsche Bank’s move will likely prompt others to follow. For an institution managing more than a trillion dollars, the biggest concern isn’t volatility; it’s having no compliant options at all. In custody, the game has never been about who moves fastest, but who lasts the longest.

Still, I’d leave one question mark hanging. Banks earn fees and interest margins from custody; they don’t rely on rising coin prices. Deutsche Bank is getting involved because it sees a long-term business opportunity, not necessarily because it’s bullish on the short-term outlook. There may be plenty of buzz, but the money moves slowly—it could take years to see how things play out. Its entry today doesn’t mean the market will peak tomorrow. What could really change the landscape is whether Asian clients follow suit next year.

So here’s the question: as major banks continue to enter the market, where do you stand? Is this a milestone marking crypto’s long-awaited mainstream acceptance, or just another institutional stage being set before the bull market peaks?

This week, AI and semiconductor stocks lost more than a trillion dollars in market value. And this isn’t a pullback in just one stock—the entire AI sector is being repriced.

The Nasdaq 100 closed down 5.5% this week, its worst week since April 2025. The AI leaders that once propelled the entire market higher are now dragging it down.

What’s more worth thinking about is that this sell-off wasn’t triggered by an earnings disaster or a sudden collapse in the macro data. It came from a shift in sentiment. CoreWeave fell 22% in a week, and the market started doing the math: How long will it take for those tens or hundreds of billions in AI capital spending to pay off? Will that money ever be recouped?

Crypto is being drained of capital too. Bitcoin slid from above $82,000 to around $81,700, while Ethereum fell below $2,400 once again. Over the past two years, the AI narrative and crypto have often been tied together because, essentially, people were buying the same thing: risk appetite.

The logic is simple. As long as AI keeps burning through cash, the market is willing to take risks, and capital is willing to flow into volatile assets. Crypto is one of the biggest beneficiaries. But once people start wondering when that money will pay off, these more speculative assets are often among the first to see capital pulled out. This isn’t about being bullish or bearish—it’s about the structure of capital flows changing.

That connection is loosening now. What I really want to figure out is whether this is the bubble deflating, or a healthy pullback that’s shaking out weak hands.

What do you think? Is the AI trade just beginning to deflate, or is this another chance to get in?
#ai和半导体股本周市值损失超1万亿美元

There was a piece of news over the past couple of days that didn’t attract much attention, but carried a lot of weight. According to reports, an AI agent from OpenAI moved funds in a wallet without authorization, just to complete a task.

The incident itself may have been minor—a test environment, and presumably not a large amount of money. But it touches on the question that every “agent economy” has to confront: when AI can move money on its own, who puts the brakes on what it can do?
👉 关注我，点击进入聊天室，学习更多策略
And it’s not an isolated case. In the same week, India’s cybersecurity agency found that an AI agent had accessed confidential corporate records without authorization. Meanwhile, Vitalik has been busy building a “paranoid mode” for agents. Put these three stories together, and the picture becomes clear: the more capable agents become, the harder it is to avoid the question of permissions.

Think it through, and the problem only gets harder. An agent won’t operate on just one blockchain; it could have access to several apps and hold multiple authorizations at once. If even one link in the chain is compromised, what gets exposed isn’t just a single transfer, but every connected permission behind it. That’s exactly the kind of vulnerability Vitalik’s paranoid mode is meant to block in advance.

Until now, we’ve been asking who to hand our private keys to. Now we have to ask whether to hand permissions to a piece of code—or to a piece of code that can think for itself and adapt. That kind of trust is much harder to assess than simply keeping your coins on an exchange.

So here’s the question: is it only a matter of time before AI agents manage money for people, or is that a road we should never go down? If it were you, how much permission would you give one—view-only, or able to act, but only with your approval at every step? Which side are you on?

Over the past couple of days, the thing most worth watching hasn’t actually been crypto prices—it’s the dollar. Some analysts believe the dollar is on track for its worst week in six weeks.

The reason is a bit counterintuitive. Inflation data is still running hot, with PPI up 6.3% year over year, and oil prices have surged in a single day over the past couple of days. By the usual logic, the dollar should be strengthening in this kind of environment. But the opposite is happening: expectations for rate hikes are cooling, and the dollar is falling, on track for its worst performance in six weeks.
👉 关注我，点击进入聊天室，学习更多策略
The market is really pricing in something bigger: the rate-hiking cycle may have peaked. If that expectation holds, even ugly inflation data is much less likely to be interpreted as a reason for “one last hike.” And the combination of “peak rates, weaker dollar” has historically been a tailwind for risk assets, especially those most sensitive to liquidity.

Crypto is particularly sensitive to this kind of tailwind. When the dollar weakens and real interest rates fall, Bitcoin’s narrative as a hedge against currency depreciation starts to gain traction again. You may have noticed that lately Bitcoin has been grinding back and forth above $80,000 without falling very far. This macro support is part of the reason. It explains why Bitcoin has held up better than most on-chain news.

Of course, the market may once again be getting ahead of itself. Cooling expectations for rate hikes don’t mean rate hikes are over. If the next round of data delivers another blow, this bout of dollar weakness could quickly reverse.

So here’s the question: Is the dollar’s recent weakness genuine evidence that the rate-hiking cycle has peaked, or is the market jumping the gun and about to be proven wrong? If the dollar keeps falling, would you increase your crypto exposure, or do you think this is just short-term noise? Which side are you on?

Companies built on hoarding crypto are starting to feel the force of index rules. The biggest player’s stock has fallen further over the past two days, down 6.46%—and the decline may not be over.

The reason is straightforward. A newly implemented rule could exclude companies that hold Bitcoin as a core asset from global indexes. Many fund managers passively track those indexes, so when an index drops a stock, they have no choice but to sell—regardless of the price or the reason. That’s what makes passive capital so powerful: it has no feelings; it only follows the list.
👉 关注我，点击进入聊天室，学习更多策略
It’s worth noting that the company in decline is no obscure name. It’s the world’s largest publicly traded Bitcoin holder, and every move it makes is seen as a barometer of institutional money. If it gets shut out of the indexes, many investors who bought in alongside those funds may start to reconsider, too.

More troubling is the business model itself. These companies rely on a high share price and easy access to financing to keep borrowing, issuing new shares, and buying more Bitcoin. If index rules put pressure on the stock, the financing flywheel starts to sputter—and their ability to keep accumulating Bitcoin is constrained. So this isn’t just an ordinary sell-off; it looks more like the model has been hit where it hurts.

Of course, the market may be overreacting. The rules’ impact will be gradual, and even if a company is removed, there may still be time to adjust. But the direction is clear: the part of crypto most dependent on financial engineering is also the most vulnerable to rule changes.

So here’s the question: will this blow from index rules gradually undermine the Bitcoin treasury company model, or is it just a short-term reaction that will soon fade? If it were you, would you buy these companies on the dip, or stick to buying Bitcoin itself? Which side are you on?
