Recently, the Supreme Court's ruling seemed to generate a lot of buzz, but the market's reaction was surprisingly calm.
Here's what happened: The U.S. Supreme Court, in a 6-3 decision, ruled that Trump's invocation of the International Emergency Economic Powers Act (IEEPA) to impose $175 billion in tariffs was illegal. It sounds like great news for risk assets, but Bitcoin only briefly broke above $68,000 before quickly falling back to $67,000, with the gains wiped out within half an hour. The current price is around $66,850, and the market clearly isn't taking this good news seriously.

An era has come to an end. In early March last year, Warren Buffett officially stepped down as CEO of Berkshire Hathaway, handing over the reins to Greg Abel. This was not just a leadership transition, but a historic moment witnessed by both Wall Street and Main Street.
You have to understand, how long Warren Buffett's career has been? When he became an almost legendary figure on Wall Street, today’s tech CEOs weren’t even born yet. No one can replicate his achievements, not only because of his extraordinary talent, but also because investing has now become democratized. You simply don’t have

Recently, tensions in the Middle East have escalated, and I noticed a well-known market observer in the crypto space posted a rather heavy warning on X. Balaji Srinivasan, a seasoned industry veteran who previously served as CTO at a major exchange, bluntly pointed out that the destruction of Middle Eastern oil infrastructure could trigger an unprecedented economic and humanitarian crisis.
His core point is quite straightforward: if all oil and gas facilities in the Middle East are truly destroyed, we're not just talking about energy shortages, but a massive surge in prices across the board—fr

Elon Musk's Twitter deal has new developments. A California jury just ruled that he made misleading statements during the acquisition process, which caused actual losses to shareholders.
The background of this case is as follows — in May 2022, Musk questioned the accuracy of Twitter's reported bot data on Twitter, resulting in the stock price dropping nearly 10%. A group of former shareholders (including retail investors and options traders) sued, claiming they suffered losses due to these statements. The jury found that posts on May 13 and 17 were indeed misleading and had a direct impact on

Recently, the EUR/USD currency pair experienced a noticeable pullback, dropping from the weekly high of 1.1616 down to around 1.1560. The decline wasn't too large, but it still indicates a rebound in the US dollar. During the Asian session, EUR/USD fell about 0.2%, suggesting the dollar is trying to recover from previous heavy selling.
The US dollar index also rebounded, climbing from around 99.00 to 99.35, a 0.2% increase. The previous drop of over 1% in the dollar index was mainly due to global central banks signaling dovish policies, combined with rising energy prices driven by Middle East

Recently, I noticed that the Vietnamese crypto market is about to undergo a major change. According to internal documents from the Ministry of Finance, Hanoi authorities plan to fully ban citizens from trading digital assets on overseas platforms starting in 2026. The logic behind this move is quite clear—Vietnam, one of the countries with the highest global crypto adoption rates (ranked fourth), sees over $200 billion worth of digital asset transactions annually. The authorities view this as a primary channel for capital outflow and want to block it.
Honestly, the underground trading market i

Many people ask me how to choose moving averages when analyzing candlestick charts. Actually, the difference between MA and EMA seems complicated, but at its core, it's just one sentence: they react at different speeds.
Let's start with MA, which is the Simple Moving Average. For example, a 7-day MA is calculated by adding up the closing prices of the last 7 days and dividing by 7 to get an average. Basically, it reflects the average cost basis of the last 7 days' chips. When I use it, I find MA looks very smooth, with a more moderate trend, making it suitable for viewing the overall trend.
EM

Recently, there have been rumors online claiming that the mnemonic phrases for Satoshi Nakamoto's wallet have been cracked. I just laugh whenever I see such posts. Let me clarify: this is complete nonsense and entirely unfounded.
Some say that 10 out of 12 mnemonic words for Satoshi's wallet have already been cracked and that it’s about to be brute-forced. But the problem is, Satoshi Nakamoto's wallet simply doesn't have mnemonic phrases. I'm not just talking out of my ass; the timeline proves everything. Satoshi created the Bitcoin Genesis Block in January 2009, and the BIP39 standard for mne

I recently fell victim to a node scam and really want to share this experience in hopes of helping others avoid the same trap.
This happened last month. I opened my wallet to check if my salary had arrived, but instead I saw a full USDT balance. I was pretty happy at the time and immediately thought about withdrawing. However, the system asked me to pay a 20% "activation fee" first to unlock the funds. That’s when I became suspicious and quickly contacted wallet support.
The support’s response shocked me—my wallet was connected to a fake custom node. Simply put, someone tricked me into adding

Recently, I’ve noticed many people rushing to enter the market when the daily KD indicator shows a golden cross, only to be harshly taught a lesson by the market. There’s an easily overlooked issue behind this: most people treat the golden cross as a buy signal, but fundamentally, it’s just indicating a shift in momentum—two completely different things.
First, let’s talk about the logic of the KD indicator itself. The K line is the fast line, and the D line is the slow line. When the K line crosses above the D line from below, it’s a golden cross. It sounds like a bullish signal, but here’s th

Playing with contracts for so long, I’ve found that many beginners get stuck on basic calculations. Today, I’ll share the contract margin formulas I’ve organized, hoping to help everyone avoid pitfalls.
First, let’s talk about margins. There are actually two ways to approach margin: one is fixed margin, where the exchange directly specifies how much you need to pay to open a contract. For example, some contracts might require a minimum of 100 USDT, non-negotiable. The other is dynamic margin, which is more flexible. It’s calculated by multiplying the contract value by the margin ratio. For exa

Ten years in the crypto world is like living a century. This phrase couldn't be more fitting for Mao Shihang.
Speaking of Shen Yu, many veteran players have heard of this name. At 21, while still a sophomore at Beijing University of Chemical Technology, Mao Shihang first encountered Bitcoin in the library. At that moment, he was deeply attracted to this decentralized digital currency. From then on, he skipped classes to hang out on overseas Bitcoin forums, researching Satoshi Nakamoto and community interactions all day.
In early 2012, Shen Yu decided to fully commit, buying a few graphics card

Many people get confused by these letters when looking at charts on exchanges. Actually, they are just units of measurement. Once you understand them, it’s very simple.
Let me organize the most common units used on exchanges so you won’t be confused when viewing data in the future. 1k stands for 1,000, which everyone should know. Then 1M is 1 million, 1E is 100 million, 1B is 1 billion, and 1T is 1 trillion.
For example, if a project’s trading volume shows 500k, that means 500,000. If you see a trading volume of 1B, that means 1 billion. These units are used when looking at market cap, trading

Recently, I’ve noticed that many beginners are still confused about concepts like bullish, bearish, bull market, and bear market. I’d like to share my understanding with everyone in hopes of helping you clarify your thinking.
Let’s start with bullish and going long. Being bullish means you believe the future price of a certain coin will rise, and you expect it will appreciate. Going long, then, is based on this bullish judgment—actually buying the asset. For example, if a coin is currently worth ten dollars and you think it will go up, you buy it. When the price reaches fifteen dollars, you se

Recently, I’ve noticed that many people still have some confusion about the concept of on-chain data. In fact, this is especially important for understanding how blockchain operates.
Simply put, on-chain data refers to all the information recorded on the blockchain—transaction details, wallet addresses, block information, and so on. Unlike traditional financial systems, this data is completely open and transparent; anyone can view and verify it. Once written, it can never be changed. That’s why blockchain is often called a “public digital ledger.”
To understand the value of on-chain data, you

Recently, there has been a shocking case in the crypto world that really warrants everyone's attention. A friend used a bank card to buy and sell U coins for arbitrage, and with only 6.8 million in transactions, he was sentenced to 3 years. The charge was concealing and disguising criminal proceeds. When I saw this case, I realized that many people have no idea what they are actually doing.
Let's talk about the most common pitfalls. If you receive funds in U coins from scams, even just once, you can be charged with aiding and abetting a crime. Someone sold 100,000 U coins to a scam group and w

Recently, more and more people are starting to seriously consider the security of crypto assets, especially after experiencing several major exchange incidents. I’ve noticed that the most discussed solution is self-custody, and cold wallets are the core tool to realize this idea.
A cold wallet is essentially an offline method of storing cryptocurrencies. Its biggest advantage is that it is completely disconnected from the internet, effectively preventing hacking attacks, malware, and other online threats. In comparison, hot wallets are more convenient for trading but are always online, making

Recently, someone asked me how to accurately catch the bottom in short-term crypto trading. Actually, I’ve been using the KDJ indicator system all along. Many people don’t know much about it, so today I want to talk about this commonly used tool by market makers.
The KDJ indicator is actually derived from the Williams %R indicator, but it adds the concept of the velocity of moving averages, making it more advantageous than the simple KD indicator. After many years of use, my biggest impression is that it’s very sensitive to short-term volatility in cryptocurrencies, especially in sideways cons

Recently, someone asked me about the logic behind Bitcoin's price fluctuations, so I decided to organize my observations.
When it comes to the reasons for the rise and fall of cryptocurrencies, many people's first reaction is "speculation," but in reality, the underlying logic is much more complex than that. Bitcoin has risen from around $15,000 over a year ago to a historical high of $126,080. This increase is indeed astonishing. But if you understand supply and demand, you'll realize that these fluctuations don't just happen out of nowhere.
First, let's look at the supply side. There are onl
