Recently, I've seen many discussions about the KDJ indicator. In fact, many beginners don't have a thorough understanding of what KDJ is. Today, I want to share my own practical experience in hopes of helping everyone.
KDJ is also called the Stochastic Indicator. Simply put, it's a tool used to determine short- to medium-term trends in stocks. It reflects the strength of price movements by calculating the price range between the highest, lowest, and closing prices over a certain period. Most software defaults to a 9-day cycle, but you can adjust it yourself.
From a chart perspective, KDJ consi

Recently, I was helping a friend clean up their computer and discovered that his system was a total mess because of mining malware. That’s when I realized that many people still don’t have enough understanding of this kind of threat. Instead of waiting until something goes wrong and then scrambling, it’s better to learn in advance how to identify and remove it.
First, you need to know that mining malware mainly comes in two types. One is a file directly installed on the computer—every time the system boots, it runs automatically. The other is more covert: it’s hidden in the website’s code, and

Have you ever wondered why everyone in the crypto community says GM every day?
At first, I didn’t quite understand. GM is short for Good Morning, meaning good morning, but in this circle, it’s much more than just a simple greeting. It’s a signal, a sense of belonging, a declaration of "I’m still here, I haven’t given up."
Think about how crazy this market is. Some days, you look at your wallet and really want to just disappear. Sometimes, everyone doubts themselves and wants to quit. But you know what? No matter how tough it gets, people still open Twitter, join Telegram, hop on Discord, and t

Speaking of Bao Er Ye, insiders in the circle have a love-hate relationship with this name. From a small butcher to a major figure in the crypto world, his story is quite inspiring. But if you delve into his rise to fame, you'll find it filled with controversy.
Guo Hongcai hails from Pingyao, Shanxi, and initially was in the beef business. In 2013, he and his wife, Jin Yangyang, went to Beijing to learn about e-commerce channels. They ended up attending a Bitcoin sharing session at "Garage Coffee" hosted by Li Xiaolai. His wife was immediately moved and bought several hundred thousand RMB wort

Recently, I’ve been looking at Bitcoin price charts and realized that the principles behind cryptocurrency price fluctuations are much more complex than I imagined. Speaking of which, Bitcoin’s recent rally has been truly impressive—rising from over $15,000 a year ago to more than $67,000 now, nearly a fivefold increase. It even hit a record high of over $126,000 at one point. What exactly is driving such huge volatility behind the scenes?
I think first we need to understand the changes on the supply side. There are only 21 million Bitcoins in total, and over 20 million are already in circulat

Recently, I’ve been studying an interesting blockchain phenomenon—I’d like to talk with everyone about MEV bots and sandwich attacks.
First, let’s talk about what MEV is. Simply put, MEV (Miner Extractable Value) is the value that miners can extract on the blockchain. Put bluntly, it’s about profiting by adjusting the order of transactions. There’s a person called jaredfromsubway.eth—his MEV bot is said to have executed more than 230,000 transactions, affecting more than 100,000 victims. You could say he’s one of the most successful bot operators in the world.
You might think, doesn’t this sou

Recently, I saw someone discussing the strategy of funding rate arbitrage. To be honest, this strategy does exist, but the risks are also significant. Let me talk about how this idea works and why most people end up losing money when they try to operate it.
The core logic of funding rate arbitrage is actually quite simple: it leverages the funding rate mechanism in perpetual contracts. During extreme market conditions, the funding rate can turn negative, meaning long positions need to pay short positions. If the rate reaches -2% to -3% or more, theoretically, traders holding long positions can

Pi Network has recently sparked renewed discussion in the community, with some claiming its valuation could reach the $3,141.59 level, backed by 100 billion tokens and 1.5x collateral support. It sounds very tempting, but I remain somewhat skeptical.
Speaking of which, if these numbers are true, Pi does have some technical highlights: PoS consensus, 5-second block times, smart contracts, decentralized governance, and a staking voting system. Low fees and transferable mining rewards also sound appealing. But the problem is, many projects are implementing these features, so they are not particul

Recently, I came across a pretty alarming case in the community that I want to share with everyone. A friend was sentenced to 3 years for buying and selling USDT, with the charge being "Concealing and disguising criminal proceeds." His bank transaction record only showed 6.8 million yuan, and he was convicted. I was quite shocked when I heard this because many people think that as long as they’re not involved in scams, they won’t get into trouble. But the reality is much more complicated than we imagine.
First, let’s talk about why ordinary people buying and selling U coins can get into troubl

Wait, when did Lee Min-ho and Song Hye-kyo get together? I really haven't seen any rumors about it. Is this recent news? It feels like it just suddenly came out.
If two big stars were really dating, paparazzi would have caught them by now, right? Or am I really offline and missed some big news? Can someone tell me what's going on?

Recently, I’ve been pondering an interesting question: What is mining, and why does this activity consume electricity equivalent to that of the 27th largest country in the world?
Speaking of what mining is, it’s essentially the process of using computer computing power to compete for and acquire Bitcoin. It sounds simple, but the underlying logic is becoming increasingly crazy. Satoshi Nakamoto mined 50 Bitcoins with a home computer back in the day, and the electricity consumption was negligible. But now? A single mining machine consumes about 35 kilowatt-hours per day, and the electricity use

Recently, I’ve noticed that many friends are still a bit confused about candlestick charts. In fact, mastering candlestick patterns can help you understand the market’s temperament, and it’s really worth spending time to study.
Speaking of candlesticks, the technical methods we use actually originate from rice market trading during Japan’s Tokugawa shogunate era. Later, they were introduced into the stock market, and by 1990, when our stock market opened, they were directly adopted. But honestly, after so many years, research on candlesticks still mainly relies on Japanese findings. Many peopl

I've seen many people recently discussing the issue of funding rates, especially when the funding rate turns negative. In fact, there's quite a bit of nuance behind this phenomenon.
Simply put, a negative funding rate means that short traders are paying long traders. This usually indicates that the price of the perpetual contract has fallen below the underlying asset's price, so those shorting need to pay fees to maintain their positions. From one perspective, it's like the market is giving a red envelope to long traders.
But this isn't just a technical phenomenon; it actually reveals market s

Lately, I’ve been thinking that many beginners in the crypto space are actually clueless about their trading situation. They clearly lose money, yet can’t tell whether they’ve already taken a real loss or if it’s just a paper loss. In fact, this is the core meaning of PnL—understanding the essence of profit and loss.
Let’s start with the basic concepts. In crypto trading, PnL is used to measure whether your investment is making money or losing money. But there’s a key point here: not all losses are the same. Some are realized gains or losses (you’ve actually sold), and some are unrealized gain

Recently, I’ve been studying blockchain development processes and truly understand why testnets are so important. Simply put, a testnet is a “practice ground” before the official launch, allowing developers to safely test new features without worrying about damaging the mainnet.
Imagine deploying buggy updates directly on the mainnet—within seconds, it could affect millions of users, causing trust to collapse instantly or even being exploited by hackers, leading to asset losses. So, the smart approach is to run everything on the testnet first, identify issues, and only then officially push to

Recently, someone asked me how leverage trading actually works and also wanted to understand the meaning of liquidation. Actually, the concept is not complicated, but the risks are indeed significant. Let me explain.
First, the basics. If Bitcoin is $50k each, and you buy one directly, that’s a regular trade. But leverage trading is different. You only need to put up 10%, which is $5,000, and I’ll cover the remaining $45,000 for you. That’s tenfold leverage. Of course, the money I lend you isn’t free—you have to pay it back later.
If Bitcoin rises to $55k, a 10% increase, and you sell and pay

Recently, the volatility in precious metals has indeed attracted a lot of attention. Gold has fallen nearly 10%, and silver has plummeted about 27%. At first glance, it seems like a major event, but a closer look at the logic reveals that this currency depreciation-driven trading is far from over.
The core issue lies in the Federal Reserve's policy shift. Since Powell signaled a dovish stance at the Jackson Hole meeting, the market has been betting on a certain logic: under enormous public debt and political pressure, the Fed will be forced to shift from fighting inflation to supporting the ec

Recently, I have been closely watching the developments surrounding Warsh, the new Federal Reserve Chair candidate. There is a very interesting paradox about him—he advocates for both "interest rate cuts" and "balance sheet reduction" simultaneously. This makes no sense in traditional economics, but he believes this is the solution to the problems.
Let's briefly review the background. Trump nominated Warsh at the end of January to succeed Powell. This individual has experience at the Fed from 2006 to 2011 and personally witnessed the 2008 financial crisis. Back then, he was known as a hawk, wa

Duterte's confirmation of charges hearing at the International Criminal Court has entered its final stage. According to investigative reporter reports from Rappler, this hearing, which concerns allegations made during the Philippines' drug war under the former president, concluded after three days of detailed testimonies, with the final day mainly focusing on closing arguments from both sides.
Interestingly, the entire hearing process highlights a core contradiction. Duterte's defense team has been working to challenge the allegations regarding systemic killings during the drug war, attempting

Recently, a noteworthy development has emerged in the RWA (Real World Asset) space. A company focused on tokenizing real-world assets, RWA INC, announced a strategic partnership with Dubai. The implications behind this move may be deeper than they appear on the surface.
Dubai has been actively building out its digital asset infrastructure. This collaboration brings together high-level UAE leadership, international investment teams, and blockchain-native technologies. The core goal is to advance institutional-grade, compliant tokenization processes. In simple terms, it’s about connecting tradit
