Recently, while studying blockchain data, I found that many newcomers are confused by the concept of "on-chain data." Actually, it's not that complicated. Simply put, it refers to all transaction information recorded on the blockchain, wallet activities, block details, and so on.
What does on-chain data include? The most basic is transaction details—who sent how much to whom and when. Then there’s wallet data, which can reveal what large holders are doing—very useful for judging market sentiment. It also includes block information, miner rewards, smart contract interactions, and more. Unlike o

Recently, I’ve been thinking about a question: what specific patterns are hidden within the bull and bear market cycles in the crypto world? This isn’t just about simple price upswings and downswings—it’s about the underlying logic of time behind it.
Just look back at history to see the clues. In 2017, when Bitcoin surged to 20,000 US dollars, everyone across the internet was shouting “straight to the moon,” and that kind of wild atmosphere still feels pretty magical when you think about it now. But then, from 2018 to 2019, prices kept plunging all the way down to a few thousand US dollars, an

I happened to see someone discussing Sun Yuchen's development trajectory, and this person is indeed quite worth talking about.
From his background, this guy was born in Qinghai in 1990. In 2007, he entered university through Peking University’s admission policy for talented students, and was even joked about as a "third-tier university dropout who made a comeback." During his study abroad in the U.S. in 2011, he received funding from Lee Teng-hui, then got involved in Bitcoin investments, earning hundreds of millions of dollars in a short period. This experience marks the starting point of all

Lately I've been thinking about a question: why do some people feel stuck no matter how hard they try, while others keep breaking through? I’ve realized the answer is actually simple—it's the determination to make money.
It's not that money can solve all problems, but lacking money definitely amplifies all issues. Without a solid financial foundation, even love, connections, and self-cultivation can easily become illusions. You'll find that when your pockets are full of money, the world you see is completely different. Others’ attitudes change, opportunities increase, and even your mindset bec

Recently, I came across someone mentioning that classic KFK prophecy post again, and I couldn't help but want to discuss it.
Back in 2019 on Douban, a person claiming to be from 2060 started a chain of over 270 questions and answers. The most astonishing part is that these predictions had an accuracy rate of over 80%. At the time, many people didn’t take it seriously, but if you look back, things like the Nepal landslide, the pandemic, Wu Yifan’s incident, and the housing market decline in the early 2020s were all predicted. The only possible loophole might be details like the host city of the

Recently, I’ve been reviewing harmonic trading and found the bearish bat pattern to be quite interesting. Many people may not be very familiar with it, but once mastered, it can provide a pretty good risk-reward ratio in actual trading.
Let’s start with the core logic of the bearish bat. It is a structure composed of four legs: XA, AB, BC, and CD. The most critical points are the termination points of B and D—these directly determine whether the pattern is valid. Point B needs to end at the 38% or 50% retracement of the XA leg; if it exceeds this range, it may develop into another pattern.
Whe

Recently, someone asked me what leveraged trading means, so I’ll give a simple example for better understanding.
Suppose Bitcoin is priced at $50k. If you buy one, that’s a regular trade. But leveraged trading works differently—you only need to put up 10%, which is $5,000, and I’ll cover the remaining $45,000. That’s tenfold leverage. Of course, the money I provide isn’t a gift; it’s a loan to you, and you have to pay it back.
If Bitcoin rises to $55k, a 10% increase, and you sell to pay me back $45,000, your $5,000 principal doubles, earning a net profit of $10k. Sounds great, right? But what

Recently, I've seen quite a few discussions about the Martingale strategy, so I want to organize some of my thoughts.
Honestly, the Martingale strategy looks very simple—doubling down. In theory, if you have enough capital, betting on the up or down side can indeed guarantee a 100% win rate, making losses impossible. But the key word here is "in theory."
I’ve realized that the biggest problem with the Martingale isn’t the strategy itself but human nature. For example, if you have a $10k capital and open a $1,000 long position, and then the market keeps falling sharply. You start adding to your

Let's talk about something every trader must understand—mathematical expectation. Many people lose money simply because they don't grasp this concept.
First, the most straightforward explanation: trading is really about having a long-term positive EV. What does that mean? It means that on average, each trade makes money, and the more you repeat this, the more you earn over time. Conversely, if your trading strategy has a negative expectation value, no matter how hard you try, it’s doomed to lose money in the long run.
Mathematical expectation, simply put, is the weighted average of all possibl

Friends who are new to the crypto world are probably confused by terms like “bulls,” “bears,” “go long,” and “shorting,” especially since these terms frequently appear when reading market analysis articles. Actually, understanding the meanings of go long and short is not difficult at all. Today, let’s go through it carefully so you can get it straight.
First, let’s talk about “go long” and “doing long.” “Go long” is easy to understand—it means you expect the market outlook for a certain coin to rise, and you believe it will go up. “Doing long,” on the other hand, is when you actually buy it. I

I recently finished reading Wykoff’s classic work and only then realized how restless I’ve been in the market all these years. To be honest, this theory has been circulating for nearly 100 years, yet I’ve only started to study it seriously now—no wonder I’ve been losing so badly.
First, let me talk about the most painful point: manipulators do exist in the market. Just think about it—if they can make money, capital must inevitably flock in. In a zero-sum game, the side with more resources has a better chance of winning. The reality, however, is that most retail investors are losing money, whic

Recently, I’ve been pondering a question: why do some people always chase after money, while those who are actually pursued by money tend to become wealthier? What’s the real difference?
I believe the key lies in mindset. Many people constantly complain about not having enough money or that earning money is too difficult, and as a result, money actually stays away from them. Money is actually quite spiritual; it can sense your attitude toward it. The more desperately you chase after it, the faster it runs away. Conversely, those who don’t treat money as the main goal and instead focus on self-

Bitcoin rebound to this position, and I see a bunch of people in the square shouting that the bull market is coming. To be honest, I’ve been used to this phenomenon for a long time. When prices go up, they look bullish; when prices go down, they look bearish. Most people are always following market sentiment, and the result is always losing money. I’ve told everyone countless times, don’t be led by this collective psychology, or you’re destined to only suffer losses in this market.
The reason I have both loyal fans and critics in this circle is because I never cater to the masses. Friends who

Recently, I've seen many people discussing stocks again and noticed that a lot of them don't understand the logic behind turnover. Honestly, if you haven't fully grasped the concept of turnover rate, you're basically guessing in the stock market.
Let's start with what turnover means. Simply put, it refers to how frequently stocks are bought and sold, reflecting how active a stock is. Some stocks are traded daily, while others haven't seen any activity in half a day. The difference lies here. What does a high turnover volume indicate? It shows that the chips are constantly flowing, and both bul

A few days ago, I was chatting with a friend and mentioned that I had bottomed out Ethereum at around 1400. Now it's risen to $2.16K, and I still feel pretty comfortable about it. Today, I want to share with everyone the logic behind this—Wyckoff Accumulation. This theory plays a significant role in my trading decisions.
Let’s start with the core principle of accumulation. I like to compare it to a merchant’s “secret maneuver.” Imagine you discover that apples in a small town are particularly valuable, but the locals haven't realized it yet. You want to buy a large amount, but buying directly

Recently, some fans asked how to read MA moving averages, so I’ll briefly talk about this most fundamental and practical technical indicator. To be honest, after I entered the crypto space, MA moving averages became one of the tools I used the most. If you can master it, it can help you avoid a lot of detours.
First, let’s talk about what MA is. A moving average (MA) line is created by connecting the average closing prices over a period of time into a curve, used to reflect historical price fluctuations and future trends. It sounds complicated, but in essence, it’s just helping you see the tru

Recently, I've been researching which P2E games are worth playing in 2026 and found that this field is changing really fast. Many people ask me if P2E games can still make money now. I think the key is to find truly fun projects.
Starting with card games, Gods Unchained is still quite interesting, with strong strategic elements, NFT card battles, and rarity determining market value. You can start playing completely for free. Parallel Life is also good—a sci-fi themed TCG game where participating in battles earns PRIME tokens, combining traditional card mechanics with blockchain well.
For role-

Recently, I've seen many discussions about an extreme hypothetical scenario: if the global situation truly spirals out of control, can traditional investment strategies still be reliable? Honestly, this topic sounds heavy, but from an asset allocation perspective, it's definitely worth considering.
My observation is that during wartime, what preserves value best ultimately depends on assets that don't rely on governments or financial systems. Gold is a classic example—thousands of years as a hard currency, maintaining purchasing power in any crisis. Silver, though more volatile, follows the sa

Recently, when analyzing candlestick charts, I’ve noticed that many people don’t have a deep understanding of the Doji pattern. In fact, the Doji is one of the most interesting signals in candlestick charts and is a key indicator for market reversals.
Simply put, a Doji pattern occurs when the opening and closing prices are basically the same, forming a horizontal line. What does this indicate? It shows that bulls and bears are evenly matched on that day, and the market sentiment is uncertain. When this pattern appears at the top or bottom of a trend, it serves as an important warning for inve

Recently, I’ve noticed that many people fall into traps when setting moving averages, especially by directly applying others’ parameters without adjustment. In fact, the key to moving averages isn’t how many lines you have, but understanding the market rhythm each line represents.
First, let’s talk about why parameter settings are so important. A moving average essentially smooths out chaotic price data, and the parameters determine how sensitive the line is to price changes. A 5MA represents the average price of the past 5 candles, while a 20MA is based on 20 candles. Smaller parameters react
