Just saw an important development from TSMC, and it feels like a pivotal moment for the entire AI optical communication industry.
Their silicon photonics integration platform, COUPE, is expected to enter mass production this year. This is not just a technological breakthrough—it also marks co-packaged optics (CPO) moving from the lab to a truly industrialized stage.
The core advantage of the COUPE platform is that it uses SoIC technology to integrate optical engines and various computing and control ASIC chips into the same package substrate or intermediary device. The benefits are obvious—com

Just checked the energy futures market, WTI crude oil futures closed today at $94.69 per barrel, and it seems there is still some fluctuation room at this price level.
At the same time, natural gas futures are reported at $2.6470 per million British thermal units, gasoline futures are at $3.1637 per gallon, and heating oil futures are at $3.8329 per gallon. The entire energy sector, including crude oil futures and related commodities, continues to fluctuate, indicating that recent geopolitical and supply factors are still influencing pricing.
If you're interested in crude oil futures, you migh

Recently, many people have asked me about the KD indicator, especially how to understand those parameter settings. To be honest, many traders use the KD indicator without really understanding the underlying logic. Today, I’ll break it down.
The KD indicator actually consists of three layers. The bottom layer is RSV, which is the raw stochastic value. Its function is simple: to see where today’s closing price stands within a certain period. The formula is (today’s closing price minus the lowest price in the past n days) divided by (the highest price in the past n days minus the lowest price in

Recently, many beginners have been asking about technical indicators, and the most easily misunderstood one is the divergence rate. Simply put, the divergence rate is a tool used to measure how far the price is from the moving average. Understanding its meaning can be very helpful for trading.
I have been using the divergence rate myself for several years, and I’ve found that many people use it incorrectly. The core logic of the divergence rate is one sentence: the price will eventually return to the average cost. When the price deviates too far, it signals overbought or oversold conditions.

最近一直在思考一個問題：我們正在用最高權限去餵養一個隨時可能被奪舍的東西。
說實話，當初看到 OpenClaw 這類 Agent 工具時，我也被它的能力震撼到了。但越深入研究，越發現一個駭人的事實——我們在做什麼？我們在主動開門迎賊。
過去黑客要進你的電腦，得費盡心機：找漏洞、寫代碼、誘導點擊、一道道防線。但現在呢？我們自己在排隊送權限。完全磁盤訪問、文件讀寫、App 自動化控制——這些曾經是黑客夢寐以求的東西，我們現在直接打包送人。黑客甚至不用動手，門就從裏面打開了。
技術史有個殘酷的規律：每一波新技術普及的紅利期，都是黑客的紅利期。
1988 年互聯網民用化剛起步，莫里斯蠕蟲一夜之間感染了全球十分之一的聯網電腦。2000 年郵件普及的第一年，「ILOVEYOU」病毒直接摧毀 5000 萬臺設備。2006 年中國 PC 互聯網爆發，熊貓燒香讓數百萬臺電腦同時燃起三根香——那些滿屏的燒香圖像，成了整代人對網絡威脅的深刻記憶。2017 年企業數字化轉型提速，WannaCry 在一夜間癱瘓 150 多個國家的醫院和政府。
每一次，人們都以為自己看懂了規律。每一次，黑客已經在下一個入口等著。
現在輪到 AI Agent 了。
我整理了五種最容易被忽視的死法，建議你對照排查一遍。

Recently, I noticed a pretty critical time window. The next four weeks could be very important for the European economy because this period will essentially determine whether Europe is facing a new crisis or just a small setback in the recovery process.
Bloomberg also mentioned on X that market observers are now closely watching the performance of the European economy. In other words, they want to see clearly how Europe's economy will move next. The data and policy trends during this period will directly influence market judgments about the overall outlook of the European economy.
If the Europ

Recently, while chatting with friends, I found that many people still have misconceptions about coin-margined contracts, so I’ll briefly share my understanding.
First, let’s talk about the most straightforward difference: U-based contracts use U as margin, and both gains and losses are calculated in U. Coin-margined contracts, on the other hand, use the coin directly as margin—so the entire profit and loss calculation is in the coin. It sounds similar, but the trading logic is very different.
Coin-margined contracts have a natural characteristic: because you first use U to buy the coin, and th

Seeing Vouched win the Authentication Award at the FinTech Breakthrough for two consecutive years, this time they directly took home the "Annual Authentication Solution" award. Interestingly, they are not only engaged in traditional identity verification but have also expanded into the new field of AI agent identity recognition, launching the Know Your Agent suite and Agent Checkpoint.
In simple terms, it’s about using AI to detect and verify the identity of AI agents to prevent fraud. The CEO mentioned that the identity field is undergoing transformation, from mobile driver’s licenses to AI a

Just saw the market data: within the past hour, cryptocurrency futures liquidation amount reached $120,000,000, which is definitely a pretty big fluctuation in a short period of time. The total liquidation amount accumulated over the past 24 hours has already surged to $539,000,000, and it looks like the market’s leveraged positions are going through a round of reshuffling.
It’s said that this liquidation wave mainly concentrated on BTC and ETH trading pairs, where BTC is currently hovering around $70.98K, with a 24-hour drop of about 0.87%. ETH is about the same, near $2.19K. All the derivati

I discovered a super interesting Bitcoin news story. Over the past six months, while almost all national governments have not sold their Bitcoin, a very contradictory opposing trend has emerged — El Salvador has been increasing its holdings from 6,376 to 7,600 coins, while Bhutan has been dumping aggressively, selling from a peak of 13,000 down to 4,000.
Speaking of Bhutan, most people's impression is that of a mysterious Buddhist country that proposed the "Gross National Happiness" index. But you might not expect that this country, which only introduced the internet in 1999 and has banned pla

Recently, I saw someone around me get scammed by a Ponzi scheme again. A friend spent over 10,000 yuan to buy a so-called Ponzi bank card and mining phone, and the person just ran off. I want to explain the logic of this scam to everyone so that no one falls for it.
First, let's talk about what Ponzi coins really are. Many people think it's some kind of blockchain project, but it's not at all. The Ponzi coin app looks very simple: download the software, click a button every day to "mine," and invite friends to speed up. Sounds a lot like a certain domestic e-commerce scam, right? It’s definite

Recently, a friend asked me what the underlying logic is behind this wave of Bitcoin market movements. I realized that to understand the rise and fall of cryptocurrencies, it’s really about understanding changes in market supply, demand, and expectations.
Let’s start with the most straightforward facts. Bitcoin rose from around $15,000 over two years ago to a historic high of $126,080 last year. That increase was indeed astonishing. But now, it has pulled back to around $70,920. There are clues behind this volatility.
First, there are changes on the supply side. Bitcoin has a total supply cap

Recently, many beginners have been confused by various terminology after entering the crypto space. I’ve decided to organize a beginner’s guide to answer some of the most frequently asked questions.
First, it’s important to understand the difference between fiat currency and tokens. Fiat currency refers to government-issued money like RMB or USD, backed by government credit. Tokens, often called coins, but more accurately called “digital assets” or “utility tokens,” represent proof of rights on the blockchain. Tokens have three core elements: they must be digital certificates of rights, secure

Recently, I’ve noticed more and more friends around me want to get into the crypto world, but many of them don’t actually understand how to get started. So I’m going to organize the basic knowledge I’ve figured out over the past few years, hoping it can help everyone.
First, let’s talk about what “trading crypto” means. Put simply, it’s buying and selling digital assets on an exchange, and earning the spread by taking advantage of price fluctuations. Bitcoin and Ethereum are the two most mainstream types. The trading mechanisms in the crypto world are much more flexible than the stock market—t

When hanging out on Discord and Twitter, you've probably seen all kinds of unique profile pictures. Behind those PFPs, there's actually a whole culture.
PFP stands for Profile Picture, simply put, your personal avatar. But in the crypto community, PFPs usually refer to digital avatars issued by NFT projects, not just casual selfies. The most classic examples are CryptoPunks and Bored Apes, which have become symbols of identity since their launch.
You'll see various styles of PFPs trending, including pixel art, cartoon characters, and some more bizarre designs like cats, dogs, and skulls. The c

Recently, while revisiting K線 chart patterns, I was reminded of an ancient saying—“once momentum is gathered, then it declines; after the third time, it is exhausted.” This logic fits especially well when applied to an M top and an m bottom.
Let’s first look at the M top scenario. On the first push to a higher level, the bulls’ momentum is at its strongest; the market is filled with bullish voices, and capital rushes in. But by the second push to a higher level, everything changes. Retail investors who were trapped earlier begin to get out and escape their positions, and early profit-taking or

Retail investors' biggest problem is not knowing where to buy or sell. I often see people shooting in the dark, only to get trapped at the worst possible positions. In fact, true experts have long mastered a secret weapon: knowing how to identify those key support points.
Did you know that less than 10% of investors can accurately catch the bottom? Why? Because they’ve learned a skill—drawing support lines. Today, I’ll break down how these trading masters operate.
First, you need to understand what a support line is. When the price drops to a certain level, the bulls see an opportunity and buy

Recently, I’ve noticed that many new traders tend to fall into traps when using RSI. The main reason is that they don’t adjust the RSI settings according to their trading style. I want to share from practical experience how to properly use this indicator.
First, the conclusion: RSI isn’t a magical tool; it’s used to judge whether the market is overreacting. When RSI exceeds 70, it indicates that the upward momentum might be a bit overextended, with a risk of a pullback; below 30 suggests oversold conditions and a potential rebound. But this is just the surface. The real key lies in how to set

Friends who are new to the blockchain space probably have experienced this feeling: everywhere you see abbreviations like PoW, PoS, DPoS, as if you’ve been transported back to an era dominated by English terms. Actually, this is quite normal—blockchain itself is a global thing, and English terminology is unavoidable. But don’t worry, today I’ll help clarify what these three consensus mechanisms are all about.
Let’s start with PoW, which stands for Proof of Work. The name says it all—you get out what you put in. Simply put, everyone works together to solve the same problem; whoever solves it fi

Many people get confused between MA and EMA when looking at trading charts. In fact, the difference isn’t that complicated—today, I’ll simply explain what these two moving averages are.
First, MA is the most basic moving average. For example, the MA7 on a 7-day K line is simply calculated by adding up the closing prices from the past 7 days and dividing by 7. The result is the average cost of the trading lots over that period. The concept is very straightforward: it shows the average price at which people have been entering the market in recent days.
EMA is more interesting. It is also a movin
