Recently, while studying technical analysis tools, I discovered that the ancient mathematical concept of the Fibonacci sequence is truly fascinating in trading.
This sequence originated in ancient India, but it was the Italian mathematician Leonardo of Pisa, known as Fibonacci, who popularized it in Europe in the 12th century. He published this simple yet elegant series under a pen name: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144… Each term is the sum of the previous two. It looks simple, but it hides the most harmonious ratio in nature—the golden ratio 1.618.
This number was discovered as earl

Tomorrow is 519 again. Do you remember that year? The black swan event in the crypto world, I still feel a bit bittersweet when I think about it. The number of people who were looted at that time is countless. That thrill of huge ups and downs, honestly, it's really hard to experience again now.
On May 19, 2021, the cryptocurrency market experienced an unprecedented crash. Speaking of which, the trigger for this 519 incident was actually quite dramatic. Elon Musk first went on Twitter to wildly promote Bitcoin, invested 1.5 billion USD with Tesla, and announced accepting BTC payments, even fre

I just recently realized a pretty serious thing—your computer that you use to browse the internet right now might be secretly being used for mining by a malware infection. This isn’t alarmist talk; it’s really happening.
I just learned that these types of malicious programs can quietly infiltrate Windows systems, and then start using your hardware resources to mine cryptocurrencies. Even worse, ordinary antivirus software often doesn’t work very well against them, and removing them can be especially troublesome.
Mining malware mainly comes in two types. One hides in online scripts on websites—

Recently, I saw someone ask what liquidation of a contract means, so I might as well organize my understanding of leveraged trading.
Let's start with the most straightforward example. Suppose Bitcoin is $50,000 each, and you have $5,000. Regular trading means saving up money and waiting until you have enough to buy. But leveraged trading is different—you can only put in $5,000, and the remaining $45,000 is borrowed from the exchange. This is tenfold leverage.
Sounds good, right? If Bitcoin rises to $55,000, you sell and pay back the loan, doubling your $5,000 principal to $10,000 profit. But t

Recently, I’ve seen many people in the community discuss the phenomenon of price spikes, so I decided to organize my understanding of this topic.
Speaking of price spikes, many traders have experienced that moment of shock— the price of a certain coin suddenly jumps up or down, then quickly returns to the original level. This strange fluctuation seems random, but there is actually a logic behind it.
First, why do price spikes occur? The root cause is not complicated. Insufficient market depth is a major factor; when there aren’t enough buy and sell orders in the market, a large order can easil

Recently, I noticed a pretty interesting phenomenon—many traders are discussing Bitcoin's top phase with decreasing volume and sideways movement, as if everyone is pondering what this pattern really means. I also spent some time整理ing it, and I feel that some things are indeed worth talking about.
Actually, the sideways pattern, simply put, is when the price fluctuates within a very narrow range over a period of time, oscillating back and forth within a relatively fixed zone, with no obvious upward trend or sharp decline. When this situation occurs at high levels, and trading volume continues t

Recently, while reviewing technical analysis tools, I found that many people have quite a few misunderstandings about MACD parameter settings. Honestly, as one of the most commonly used indicators, MACD looks simple, but to really use it well, adjusting its parameters is definitely worth spending time on.
Let's start with the standard 12-26-9 set of parameters. The fast line EMA (12) captures short-term momentum, the slow line EMA (26) reflects long-term trends, and the signal line EMA (9) is used to generate trading signals. This set of settings is chosen as the default by major trading platf

I recently came across a set of old photos that show Lin Huıyin after giving birth. In 1929, she had just given birth to her daughter, Liang Zaibing, and her body hadn’t fully recovered yet, but Liang Sicheng kept taking photos beside her. Three years later, when their son Liang Congjie was born, he did the same again. At first glance, it may seem inconsiderate, but in fact it reflects the couple’s understanding of life—Lin Huıyin believed that childbirth was an important moment in a woman’s life and should be recorded properly, while Liang Sicheng fully supported her view.
Their story is actu

Recently, many Pi fans have been discussing and some even expect Pi to rise to $314,159 per coin. I have to say, while this idea is full of imagination, from a market reality perspective, it’s highly unlikely. Let’s have a rational discussion about the potential value of Pi Network.
Pi Network was launched by Stanford alumni in 2019, with the core innovation being its use of the Stellar consensus protocol instead of traditional proof of work, allowing ordinary users to participate easily with their phones. Currently, it is still in the closed mainnet phase; once it lands on major exchanges and

Actually, many beginners don't clearly understand the difference between full position and isolated margin. Today, I'll clarify the core distinctions between these two modes.
Let's start with the full position mode. This method uses all available balances in your account as collateral, which has a clear advantage— as long as your leverage isn't set too high, it's generally difficult to be forcibly liquidated. Because the entire account balance supports your position, institutions and seasoned traders who do hedging especially prefer this mode. But conversely, in extreme market conditions, loss

Recently, I noticed a new move by Naval Ravikant. He co-founded the USVC fund, which has officially opened for investment opportunities, with the minimum threshold lowered to $500. This is quite interesting for retail investors.
The name Naval Ravikant is well-known in the venture capital world, as the co-founder of AngelList, and he has been dedicated to democratizing investment channels. This time, the USVC fund targets companies that haven't gone public yet but have huge growth potential, including unicorn-level growth companies like OpenAI and xAI.
Honestly, this model is quite disruptive

There’s a story I’ve always wanted to tell properly—a story about a young man who changed the entire crypto world.
In 2014, a young Russian man came to Hangzhou to attend an exhibition. At the time, his name was Vitalik Buterin, and later everyone called him V God. At the event, he generously distributed 5,000 virtual coins, hoping to help people understand his technology. But you know what happened—almost everyone doubted him, and some even cursed him as a scammer to his face. However, those 5,000 coins that had been given away for free ended up climbing to $150 million. That was Ethereum—ETH

Recently, I saw someone discussing Bitcoin mining issues again, so I decided to organize some of my observations. Speaking of Bitcoin, many people actually don’t understand what mining is or why a virtual thing needs to consume so much electricity.
In simple terms, Bitcoin mining is the process of using computers to perform extensive calculations to obtain Bitcoin. It may sound like nothing special, but the problem is that as more people participate, the difficulty of mining keeps increasing. This is related to Bitcoin’s underlying design mechanism. There are only 21 million Bitcoins in total,

After spending a long time in the trading market, you will definitely encounter this phenomenon that people love and hate at the same time — the bull trap. Recently, I saw a few friends suffer losses from this, so I think it’s necessary to have a good discussion.
Simply put, a bull trap occurs when the price suddenly breaks through a key resistance level upward, seeming to signal the start of a rally, but then the price quickly reverses downward, trapping those who entered early. This situation is especially deceptive to experienced traders because the breakout itself looks very much like a ge

Recently, a friend asked me about leveraged trading, so I thought I’d organize my understanding and share it with everyone.
In simple terms, leveraged trading is using borrowed money to amplify your trading position. You only need to put up a portion of the principal as margin, and the platform allows you to control a larger amount of assets. For example, with 10:1 leverage, investing $10k allows you to operate a $100k position. This method is common in stock, forex, commodities, and even cryptocurrency markets.
Leverage ratios vary greatly across different markets. Stock markets usually have

Recently, some beginners have asked me how to use RSI, so I might as well organize my understanding of this indicator. To be honest, RSI is one of the most intuitive technical indicators, especially suitable for newcomers to quickly get started.
Let's start with the most practical part. RSI uses a value from 0 to 100 to measure the strength of price movements over a certain period. Above 70 indicates the market may be overly optimistic, while below 30 suggests excessive pessimism. It sounds simple, but this overbought and oversold logic can indeed help you avoid many risks. My personal habit i

I've been seeing people put goat emojis next to sports stars lately, and at first I didn't really get what it meant.
Later I realized that GOAT isn't actually a goat, but an abbreviation for Greatest Of All Time, meaning "the most legendary in history."
It's pretty interesting, using a goat to represent this concept.
The reason Messi and Ronaldo are called GOATs is because their achievements in football history are truly unmatched.
Think about it—one player scoring 40+ goals every year for 17 consecutive years, winning countless awards and assists, that's not something ordinary people

Recently, I've seen more and more people talking about quantitative trading, and honestly, I'm a bit surprised. Most retail investors' so-called quantitative trading systems are just buying ready-made apps or code scripts from others. The logic behind these is actually very simple—if someone could truly do quantitative trading and consistently make money, even promise perpetual profits, why would they bother to sell this stuff? It's worth thinking about this question.
Taking Fantom Quant as an example, it's a well-known top-tier quantitative company in the industry. Does founder Liang Wenfeng

Recently, AI videos have been flooding the internet, especially after seeing the effects created with Seedance 2.0, I finally understand why so many people are into this. I was still wondering how to get started quickly, but then I realized it's not that complicated.
ByteDance's Yimeng AI launched Seedance 2.0 in February this year, and honestly, it’s quite user-friendly. What attracts me the most is that you can upload text, images, videos, and audio all at once, and the system automatically generates a 5 to 12-second video. Plus, the lip-sync matching feature is truly excellent. I tried uplo

Wait, when did Song Hye-kyo and Lee Min-ho get together? Why did I just hear about this news? Have I been too busy lately and not paying attention to entertainment news? Or was this announced recently? It feels so sudden, how did these two end up together? Can someone tell me what happened?
