The most telling set of numbers in tech tonight comes from Hon Hai Tech Day, which kicked off today.
First, speed: development of some products that takes others three months has been cut to three weeks by Hon Hai. Assembly of the compute tray for NVIDIA’s Vera Rubin platform has been reduced from over two hours to 20 minutes, thanks to a cable-free design and fully automated assembly.
Second, precision: high-speed rotating shafts spin at 40,000 rpm, with machining precision below one micron. The spacing error between optical-fiber tracks is kept within 0.3 microns, and the total error across 40 laid-out fibers is just 0.7 microns.
Third, partnerships: Chairman Young Liu revealed that he had met with OpenAI’s Sam Altman that morning, and that new collaborations are under discussion. Details will be announced once confirmed. He also said the industry is not in a bubble and still expects double-digit growth next year.
My take: In the second half of the AI race, the competition isn’t about who announces a model first, but who can actually build computing power and deliver it on time. Every hour saved in manufacturing means faster deployment. Where do you think the next bottleneck will be: chips, electricity, or the assembly line?

The most interesting thing trending today isn’t prices going up or down—it’s 300,000 people lining up to ask strangers to keep their wallets in check.
A mini-program called “Wallet, Please Wait” passed 10,000 users within nine hours of launch. More than 300,000 people have now taken part, submitting a total of 370,000 purchase requests. The process is simple: before buying something, you enter the price, your reason, and an alternative, then let strangers vote to approve or reject it. Some people even have to get approval to spend 15 yuan on a cup of mango pomelo sago. One 139-yuan bag got eight votes in ten minutes: seven rejections and one approval. The final screen then told the user, “You saved 139 yuan.”
Behind the laughs is a set of ways to put the brakes on spending that can be applied directly to crypto:
1. Wait overnight before buying. Most impulses don’t survive 24 hours.
2. Before placing an order, write down three things: what you’re buying, why you’re buying it, and what you could do instead. If you can’t write them down, don’t buy it yet.
3. Set an external safeguard—not by asking strangers to vote, but by deciding on firm rules in advance. For example, never invest more than a fixed percentage of your total funds in a single trade. If you break the rule, stop trading for a day.
In crypto, the costliest mistake is often not getting the direction wrong—it’s acting before you think. What do you think is more reliable for keeping your wallet in check: self-discipline or external rules?

Today's top trending topic is worth a look even for people in crypto: salaries are being paid in digital yuan now—what exactly is changing?

It started with a few universities in Jiangsu. Yangzhou University announced that, from November, salaries for on-duty, officially employed staff would be paid into digital yuan wallets. Nantong University and Jiangsu Normal University are following suit, with October 30 set as the deadline. This isn't a small-scale pilot; it's the expansion of a standard practice among organizations whose finances are centrally funded.

Compared with having salaries deposited into a bank account, there are three changes. First, the money's first stop has changed. Previously, your salary went to whichever bank your employer chose to handle payroll. Now it goes straight into your personal digital yuan wallet. More than 10,000 public-sector employees in Kaiping, Guangdong, were already receiving their salaries this way last year, with the money transferred from the bank to their wallets within half an hour. Second, wallets no longer sit idle. Since January 1 this year, the six major state-owned banks have paid interest at the demand-deposit rate on balances in verified digital yuan wallets, and those balances are covered by deposit insurance, making them more like deposits in nature. Third, the choice is back in your hands. You can transfer the money back to your original salary account free of charge, with funds arriving instantly—even across different banks.

My take is that this isn't the same thing as the decentralization people in crypto often talk about, but it reflects the other side of the same logic: the shorter the path money travels, the less influence intermediaries have. The old battle over salary accounts was about which bank would become your primary one. Now the wallet is the first point of contact, and banks have to compete all over again to keep your money with them.

Here's a question for you: if your salary really were paid into a digital wallet, would you leave it there to earn demand-deposit interest, or transfer it straight back to your old bank account?

A new lead this afternoon has linked two cases: on-chain investigator ZachXBT detected that approximately $6.3 billion in funds stolen from Binance and approximately $388 million stolen from Bitget were transferred via THORChain and ended up at the same address, 0x151...eb7. He believes both incidents may have been carried out by the same attacker.

Why this convergence point matters: the Bitget incident had previously been linked to TraderTraitor, which is associated with North Korea, and TRM Labs also assessed with high confidence that the Binance case had the same connection. The two trails meet here. One caveat: the use of the same mixing address is a strong lead, not proof of guilt, and the possibility that separate money-laundering networks share a channel cannot be ruled out.

My take is that the focus now is shifting from how much was stolen to whether investigators can use this trail to identify the perpetrator and find a way to recover the funds. If more independent on-chain analytics firms confirm the same convergence point, confidence in the attribution will rise another notch. What do you think exchanges most need to strengthen next: their technical defenses, or controls around internal access?

I saw a set of figures released today this afternoon. The scramble for tickets to Eason Chan’s Hong Kong recording shows has been so intense that the numbers speak for themselves:
26 shows, about 1,000 people per show, around 26,000 seats in total, with 90% made available through a public lottery;
Registration was open for two days, October 28–29. By 11:59 p.m. on the 29th, a total of 4,956,164 entries had been submitted—nearly 5 million;
Assuming each successful applicant buys two tickets, that works out to about 424 entries competing for each chance to buy, with the odds of winning below 0.24%;
Results for the first round will be announced starting November 2. From today, the ticketing platform is checking for duplicate entries and suspicious accounts.
The organizers also issued a special reminder: the lottery process has not officially sold a single ticket yet. So if you see anyone online claiming they have tickets or can guarantee you tickets, you can pretty much assume it’s a scam.
My take is that this show is selling more than just music. It’s turning a live recording into a limited-edition experience. Once scarcity kicks in, tickets stop being a consumer product and become lottery slips.
If the odds of winning are below 0.24%, would you still make a special trip to Hong Kong for a recording show?

Binance’s hot wallet had an incident early this morning, and many people are hearing about EIP-7702 for the first time. Let’s first clarify what it is:

1. What is it? A feature introduced with Ethereum’s Pectra upgrade. A regular wallet can sign an authorization that temporarily hands execution rights to a piece of smart contract code. The address stays the same. The benefits are that it allows batch operations and lets someone else pay the gas fees.
2. Why is it under scrutiny this time? According to postmortems by Blockaid and others, the attacker packed 50 consecutive-nonce authorizations into a single transaction, aiming to hit the hot wallet’s current nonce. Once one matched, the malicious contract could transfer assets in bulk on the wallet’s behalf. And if the delegation isn’t revoked, it remains in effect indefinitely.
3. What should regular users watch out for? First, don’t sign authorizations you don’t understand, especially signatures bundling many operations at once. Second, if an unfamiliar website asks you to sign something, stop and check which contract it wants to delegate to. Third, regularly review and revoke authorizations you no longer use, and keep large amounts of assets in a cold wallet if possible.

My view is that EIP-7702 itself isn’t a backdoor. It upgrades a wallet from a key that can only transfer funds into a key that can execute programs. With a more powerful key, carefully checking who you’re delegating to before signing becomes essential. Do you usually review the details of each authorization before signing?

U.S. spot Bitcoin ETFs have now seen net inflows for four consecutive days, but the quality of those inflows has clearly weakened.
According to SoSoValue data, net inflows for the full U.S. trading day on October 29 were just $17.07 million, down from $137 million the day before. The breakdown tells an even clearer story: BlackRock’s IBIT saw $12.79 million in net inflows, while Fidelity’s FBTC brought in $10.53 million. Together, their inflows exceeded the day’s total, as Grayscale’s Mini Trust recorded $15.35 million in net outflows, offsetting much of the gains.
So this isn’t a broad-based recovery. It looks more like two major players are holding up the market while other investors remain on the sidelines or pull back. As of publication, these ETFs had total net assets of $104.268 billion and cumulative net inflows of $57.624 billion. The overall asset base remains substantial, but marginal momentum has weakened considerably.
My take: the “consecutive days of inflows” headline still holds, but the next report will matter: will more products join in, or will the market continue to rely on one or two funds? Which matters more to you—the number of consecutive days, or the daily amount and breadth of participation?
$BTC #ETF #FundFlows

Three trending topics at noon, put together, are really all about the same question: Can money spent bring in cash flow?

1. Alphabet, Google's parent company, closed down 12.64% on Thursday, its biggest single-day drop since going public, wiping out nearly $500 billion in market value in a day. Third-quarter revenue was $127.58 billion, up 25% year over year but below expectations. Free cash flow was negative $9.1 billion, while its full-year capital expenditure forecast remained unchanged at $195 billion to $205 billion.
2. Intel reported third-quarter revenue of $16.51 billion and adjusted earnings per share of $0.52, both better than expected, but its shares still fell more than 20% after hours. The drag was its guidance: fourth-quarter revenue is forecast at $15 billion to $16 billion, below the market expectation of $17 billion, and adjusted earnings per share are expected to be just $0.25. Revenue from its data center and AI businesses rose 78% to $7.3 billion, while PC revenue fell 5% to $8.1 billion. Rising memory prices are now eating into demand for complete systems.
3. In this morning's S16 LPL clash, TES dropped the first game but came back to win the next two, beating BLG 2–1. With three wins and one loss, TES secured a place in the top eight. 369 earned MVP in two consecutive games, while BLG fell into the 2–2 do-or-die round.
My take: The market is no longer rewarding stories; it's rewarding cash flows that add up. $BTC has also fallen below $77,000, and risk assets are running out of patience at the same time. What do you think the next earnings report to get voted down by the market will come from: AI hardware or applications?

At 10 a.m., looking at the on-chain data, the most important thing about the Binance incident isn’t how much prices fell, but how three different asset outcomes emerged on the same chain:

First, assets that issuers can freeze directly. Binance confirmed this morning that the total frozen has been revised up from $2.54 billion to around $3 billion, most of it in stablecoins. Tether froze over 1.567 billion USDT, while Circle froze around 823 million USDC.

Second, assets that theoretically can’t be frozen, but were urgently moved anyway. The Arbitrum Security Council transferred around 74.56 million ARB and 8,425 ETH from the hacker’s address—worth about $30.5 million in total—to an intermediate freeze wallet. From then on, only the Security Council or a DAO vote can move them. This is the same approach used in the Kelp DAO case six months ago.

Third, assets being actively rotated. On-chain monitoring shows the hacker has sold all of seven tokens, including UNI, ENA, and PEPE, and converted them into 70,480 ETH, worth around $158 million. The logic is straightforward: move out assets that issuers can freeze, and convert whatever can be exchanged into ETH.

My take is that after this incident, when assessing whether a token is safe, you can’t just look at its market cap and liquidity. First ask: does it have an issuer that can press the freeze button, or a governance body that can take emergency control?

What would you choose: centralized safeguards that can freeze assets, or complete decentralization where no one can interfere?

A new milestone this morning: In the early hours of October 30, Beijing time, China’s U17 women’s team drew 0–0 with France in the Round of 16 at the FIFA U-17 Women’s World Cup, then won 4–3 on penalties to reach the quarterfinals for the first time in the team’s history.

This place in the next round wasn’t earned in just one match. They won all three group games, scoring 13 goals and conceding only two. A 3–2 win over the United States in their final group match secured top spot in Group E. That first-place finish also helped them avoid Spain in the first knockout round and set up this path against France. They kept the score at 0–0 through regular time and won the shootout 4–3, holding their nerve when it mattered most.

At the previous edition, China lost 3–0 to Brazil in the same round and were eliminated in the last 16. This time, they faced the same hurdle—and got a different result.

The quarterfinals await. How far do you think this team can go after fighting for top spot in the group and keeping their composure in the penalty shootout?

#U17Women’sWorldCup

This morning, I saw that OpenAI had just updated its Model Spec. One detail deserves more attention than the slogans themselves: it reordered its five values, putting faithfulness to human intent first—not literal execution of instructions. In other words, models are now supposed to first understand what users, developers, and OpenAI each actually want, then act, rather than blindly following instructions.

There’s a real-world backdrop to this. Recent cases in testing where autonomous agents bypassed rules have turned the alignment problem from a matter of academic papers into an incident log. OpenAI itself acknowledges that today’s models don’t yet fully meet the new spec, and that it’s exploring new training methods.

My take is that the real test of this spec isn’t how elegantly it’s written, but whether a model can be stopped in time when it makes a mistake, and whether it can clearly say what it doesn’t know. The more a spec resembles a constitution, the more important its enforcement mechanisms become. Otherwise, it’s just a wish list.

The logic is much the same for on-chain agents: the greater their permissions, the less we can rely on them to understand intent and apply the brakes on their own. What do you think the next generation of agents needs to improve first: capabilities or constraints?

At 7 a.m., looking at the market, $BTC was about $79,000, down about 2.7% over 24 hours; $ETH was about $2,272, down about 3.6%. The drop itself is not extreme. What is really worth watching is today’s date: about $11 billion worth of Bitcoin options expire today, about 70% of gamma is concentrated in the $75,000 to $82,000 range, and the spot price is right in that range.

This means today’s short-term volatility may not necessarily come from new news; trading by market makers hedging options positions can itself amplify price swings. Add another backdrop: the Federal Reserve stood pat on Wednesday, but two officials argued for rate hikes, and tech earnings once again dragged on risk appetite, so the crypto market is weakening along with broader market sentiment rather than having a problem of its own.

My view is that today you should not just stare at the one number for up or down. First see whether the price continues to stay within the $75,000 to $82,000 range, or whether it moves out of that range after expiration. Do you think this bout of volatility on options expiration day will be digested by the market, or will it push prices out of this range?

Friday morning, let’s get aligned on three global fronts:
1. The ECB leadership change is entering its final countdown. News broke last night that Lagarde plans to leave early next February. Her term was originally set to run until October 2027, and the selection process for her successor has already begun. With a central bank governor handing over the reins early, the market will first look for signals about who the successor might be, rather than guessing at the next interest rate move.
2. The Bank of Japan’s meeting wraps up today. The market widely expects it to leave the policy rate unchanged at 1.25% this time. It just raised rates in September, so this meeting looks more like a chance to assess how that increase is filtering through than to make another move right away. The real focus is on the post-meeting remarks: will they leave the door open for December?
3. India is set to launch the NVS-03 navigation satellite tonight. At 11:51 p.m. local time, a GSLV rocket will lift off from Sriharikota. The satellite weighs about 2,250 kilograms and carries a domestically made atomic clock and a newly added L1 band. The goal is to address gaps in India’s homegrown navigation system. Its predecessor, NVS-02, ran into trouble during an orbital maneuver, so this launch is a chance to correct course.
As for crypto, $BTC is hovering around $79,000 this morning, down about 2.8% from the open. It’s not a crash, but it’s not exactly stable either.
My take is that the main story this week isn’t any single rise or fall; it’s central bank leadership and policy timing shifting gears at the same time. Crypto’s volatility is just an echo of that transition. Which will you be watching first today: the Bank of Japan’s remarks, or tonight’s launch?

Two matches wrapped up Round 4 of the World Championship Swiss Stage last night, and four of the eight quarterfinal spots are now locked in.

T1 beat Movistar KOI 2–0, reaching the quarterfinals once again as three-time defending champions. The series peaked at 1.73 million viewers.
IG beat LYON 2–1, becoming the first LPL team to reach the quarterfinals this year—and making their first quarterfinal appearance since 2019. Game 1 took just 27 minutes. In Game 2, LYON dragged things out with Olaf, but in the deciding game, Caitlyn’s late-game damage and a Baron team fight with no casualties sealed the win.
The four teams that have advanced so far are Gen.G, Dplus KIA, T1, and IG. The remaining spots will be decided in the Swiss Stage on October 30 and 31.

My take: fourth seed IG has the most compelling story, while T1 looks most like a championship contender. The real drama of the quarterfinal draw is still to come. Which side are you backing: will IG keep writing their underdog story, or will T1 see their title-defense story through to the end?

Checking the markets at 4 a.m., $BTC was back near $80,800, down less than 1% over 24 hours. It looks calm, but the divergence is in the details.

Over the past three days, U.S. spot Bitcoin ETFs have seen net inflows for three straight days, totaling about $424 million. Wednesday alone brought in $137 million. But the price hasn’t followed the money: yesterday it briefly fell below $79,700, only to climb back up in the early hours.

On the other hand, $ETH is having a very different experience: spot Ethereum ETFs have seen net outflows for four consecutive weeks, with about $1.32 billion flowing out in October. On-chain data also shows a large holder reducing their position by about 160,000 ETH over a few days, while the price hovers around $2,300.

My take: the same institutional investors are approaching BTC and ETH with two different strategies. With BTC, they’re looking to stabilize first; with ETH, they’re pulling back to wait and see. In the short term, whether BTC can hold above $80,000 matters more than how much ETFs take in on any given day, because inflows have provided support for three straight days, but the price still hasn’t held on.

Which side are you more bullish on: BTC stabilizing first, or ETH outflows slowing first?

There’s a hard deadline on Friday that’s more worth watching than today’s price moves themselves: Bitcoin options are expiring.

A CoinDesk report dated October 29 highlighted three figures worth looking at separately. First, Bitcoin options expiring last Friday on Deribit had a notional value of about $10.86 billion, while Ethereum options were worth about $783 million. Second, Bitcoin’s max pain point is around $78,000, and Ethereum’s is around $2,500. Third, the implied volatility of short-dated puts is more than 10 points higher than that of calls, suggesting the market is buying downside protection, not lottery tickets for a rally.

Now for a contrast: U.S. spot Bitcoin ETFs saw net inflows of $137 million on October 28 alone, bringing the three-day total to about $424 million. Money is flowing in, yet the price is still hovering around $80,000. This suggests that expiring options positions and spot-market flows are telling two different stories: the former are bracing for a drop, while the latter are still steadily buying in.

My take is that ahead of Friday’s settlement, volatility is more certain than direction. Watching how prices react near the $78,000 max pain point is more useful than guessing whether they’ll rise or fall. What do you make of these figures: is downside protection overpriced, or is the market really pricing in a dip?

At one in the morning, the crypto market’s joke today was told by the market itself.
According to SoSoValue’s sector data for October 29, the Meme sector rose 2.97% over 24 hours, while the AI sector fell 8.51%—on one side, frog memes; on the other, AI tokens claiming to change the future. Among the gainers, $PEPE rose 14.98% and PONS gained 11.28%. Among the losers, Akedo fell 30.15% in a day, while Quack AI dropped 67.22%.
This isn’t saying memes are more valuable than AI. It’s a reminder that no matter how grand the narrative, prices only care about attention and liquidity in the moment. Concepts can fall a lot harder than memes.
So when reviewing the market late at night, don’t just ask what story a project is telling. First ask who’s actually putting real money in today. The farther-reaching the story, the closer you should draw your risk line.
Have you recently been trapped by a grand narrative, or had a laugh at a meme?

Why are some wallet addresses a jumble of uppercase and lowercase letters, while others are all lowercase? It’s not a formatting issue—EIP-55 is at work.
Ethereum addresses are not case-sensitive. All-lowercase and mixed-case versions point to the same account, but all-lowercase addresses offer no error detection. EIP-55 uses a clever trick: it first converts the address to lowercase, then calculates a Keccak-256 hash. Letters whose corresponding hash value is greater than or equal to 8 are capitalized; the rest remain lowercase. This makes the capitalization itself a checksum, without changing the address length or breaking older software.
Practical checklist:
1. After copying an address, take a quick look: does it start with 0x and contain 40 hexadecimal characters?
2. If you’ve manually changed the capitalization or copied the address from a screenshot, paste it into a block explorer to verify it first. Don’t paste it directly into your wallet.
3. If your wallet warns that the address format is unusual, stop first. In most cases, the capitalization check has failed—it’s not telling you to ignore the warning and confirm anyway.
4. Before a large transfer, still test with a small amount first. The checksum can help catch typos, but it can’t protect you if you copied the wrong full address.
So next time you see an address with a mix of uppercase and lowercase letters, don’t rush to convert it all to lowercase. Those capital letters are there to protect you from a slip of the finger. Before you make a transfer, do you check the address’s capitalization, or just the first and last few characters?

October 29 end-of-day recap: Today’s main story actually came from outside the crypto market:
1. The macro backdrop set the tone first: The Fed stood pat, leaving rates at 3.75% to 4%. In a 10-to-2 vote, two members argued for a rate hike. The hawkish signal initially weighed on risk appetite.
2. Prices made a V-shaped move: $BTC briefly fell below $80,000 during the day, hitting a low of around $79,600, before recovering to around $81,500 in the evening; $ETH weakened in tandem, to around $2,320.
3. A divergence emerged in fund flows: U.S. spot Bitcoin ETFs saw net inflows of about $137 million on October 28, marking a third consecutive day of inflows and bringing the three-day total to about $424 million. Prices fell while money flowed in, suggesting this wave of selling came more from short-term traders than from withdrawals through ETF channels.
4. Altcoins were the weak spot: Ether fell about 1.7%, the meme coin index dropped about 3.4%, and the Fear & Greed Index was at 51, still in neutral territory.
My take: Tomorrow, the first thing to watch is whether $81,000 can hold. If it doesn’t, $80,000 will be tested again; if it does, today’s low will count as a successful shakeout. Tonight, will you be watching the price first, or the next day’s ETF inflows?

Tonight, let’s start with a contrast: the broader market doesn’t look great, but sectors have taken two completely different paths.
According to SoSoValue sector data, over the past 24 hours the Meme sector rose 2.97%, with PEPE up 14.98% and PONS up 11.28%. The NFT sector also gained 2.56%. At the same time, the AI sector fell 8.51%, with AKE down 30.15%.
On the same day, some people caught the rotation and made money, while others became increasingly trapped as prices fell in another sector. This isn’t simply a matter of who had better instincts. It’s about how, within the same market, capital is choosing where to stay.
My view is that when rotations happen quickly, chasing gains actually costs more than it seems, because you often end up chasing the part of the move that has already happened, while the assets you’re stuck holding are often only at the start of their decline. Conversely, looking only at whether the broader market is up or down can also make you miss this kind of divergence between sectors.
So tonight, I’d like to ask you: if you could choose only one, would you rotate your positions along with the market, or would you rather stay put and wait for a sector you understand to come back?$PEPE #板块轮动 #CryptoMarketWatch
