Before entering the crypto world, you really need to understand these trading fundamentals; otherwise, it’s easy to fall into traps when analyzing virtual currencies.
First, you must know the biggest difference — the crypto market operates 24/7, all year round, with no holidays like May Day or National Day, and no weekend closures. Users are scattered worldwide, and market fluctuations at different times are completely different. That’s also why some say the crypto market is more exciting than the stock market, because there are no daily limit restrictions; prices can plummet to zero in a seco

I’ve been tracking the Windows 98 revival project since 2023, and today I want to share some exciting new solutions to watch for in 2026.
Actually, over the past few years, we’ve already tried many methods. The DOSBox family essentially emulates the x86 processor through software, with derivatives like DOSBox-X and DOSBox Pure adding Voodoo 3D acceleration card emulation, allowing you to run Windows 95, 98, and Me programs directly. There are also emulators like 86Box, which can fully restore the nostalgic BIOS boot screen and emulate Voodoo 3 3000 acceleration cards, providing better compatib

I just saw that gold has dropped again today, falling below $4,300, and silver has also declined by 5%. Most people are shouting to sell when they see these news, but an analyst who has studied commodity cycles for many years, Kevin Smith, is going against the trend.
His perspective is very interesting: now is the opportunity to buy gold mining stocks, and he even recommends directly selling S&P 500 funds to switch into gold mining stocks. It sounds bold, but he supports it with historical data.
During the Yom Kippur War in 1973, Arab oil embargo caused oil prices to surge by 287%. At that tim

Recently, I've been reflecting on interpersonal relationships and realized I used to be way too timid. I was always habitually trying to please others, but as a result, the more I was kind to people, the more arrogant they became. I only truly understand this now.
Actually, many problems stem from myself. If you have no principles, or have principles but lack the courage to uphold them, others will gradually test your bottom line. It's like at first everyone is very polite, but with each interaction, the other person subtly tests your temper. Once they discover you're timid, they will escalate

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
