Recently, I’ve seen many people online say their computers have slowed down and the fans have been spinning like crazy—only to find out they were infected with a mining virus. This kind of thing is actually more common than you think. I decided to put together a practical protection guide to help everyone avoid getting fooled.
First, you need to understand what a mining virus is. Simply put, hackers secretly install a program on your computer and then use your CPU and graphics card to mine cryptocurrencies, so they can make money themselves. Some viruses are downloaded directly as files onto y

Recently, I was organizing my stock trading notes and suddenly realized something many people overlook—turnover rate. Honestly, if you're still judging cheap or expensive solely by stock price levels, you're just fooling yourself.
First, the most straightforward explanation: turnover rate is the frequency of stock buying and selling transactions, reflecting how active this stock truly is. You can understand it this way: a high turnover rate indicates the stock is changing hands frequently, showing that the market pays a lot of attention to it. But there's a trap—high turnover doesn't necessari

When I review my trading records recently, I find myself thinking again about the inside bar pattern. To be honest, if you can truly master it, it can be incredibly helpful for long-term trading.
In simple terms, an inside bar is a price movement that appears when the market is in hesitation. It consists of a mother bar and a following “child” bar: the child bar is completely hidden within the mother bar’s range, with both the high and low staying within the mother bar’s boundaries. This pattern may look simple on the surface, but behind it lies what the market’s mindset looks like at that mom

Recently, many people have become interested in day trading; some say it can lead to quick profits, while others lose everything. I’ve spent time organizing findings from regulatory agencies and academic research, and I want to share some practical insights for those considering trying it.
First, the conclusion: both regulators and studies indicate that most retail day traders actually lose money after deducting fees and taxes. But this doesn’t mean it’s impossible—just that the risks are very high and require special caution.
What is day trading? Simply put, it’s buying and selling within the

Recently, many friends have been confused about the concept of Gas on Ethereum, and this is actually a very good question. I was also overwhelmed by various explanations before, but I later realized that as long as you remember a simple formula, you can understand everything: Cost = Quantity × Price.
Actually, what is Gas? Simply put, it’s like gasoline needed for a car to run; all operations on the Ethereum network also require Gas to execute. You can think of Gas as the "fuel" for this blockchain network.
Let me explain in the most straightforward way. Suppose you want to drive from point A

Recently, I’ve been chatting with a few traders and found that many people actually don’t understand leverage very well. They often treat the maximum leverage ratio advertised by the exchange as the actual ratio they should use, and as a result, they go all-in right away, only to be taught a harsh lesson by the market. I’ve also experienced this misconception myself, so today I want to seriously discuss the difference between leverage ratio and actual leverage, which is really crucial for surviving in the derivatives market.
First, let’s clarify one thing: leverage ratio and actual leverage ar

Recently, many friends from the mainland have asked me about the legality of virtual currencies in Hong Kong. In fact, this reflects an interesting phenomenon— as Hong Kong’s virtual asset policies become more and more open, more and more people are beginning to seriously consider entering this market through official channels.
I’ve noticed that many people have misconceptions about this topic. In reality, the legality of virtual currencies in Hong Kong already had a clear legal framework as early as 2023. The Hong Kong Securities and Futures Commission has officially allowed retail investors

Just now I was reviewing basic trading knowledge and found that many beginners actually don't quite understand the concept of "shorting." Rather than calling it a professional term, it's more accurate to say it's one of the most easily misunderstood words in trading. Today, let's break it down and talk about it.
First, it's important to say that the meanings of "long" and "short" are actually very simple—they are two opposite judgments traders make about the market direction. A long position is bullish, expecting prices to go up; a short position is bearish, expecting prices to go down. But th

When trading perpetual contracts, many people only focus on market trends but overlook a hidden cost killer—the contract transaction fee. I also suffered from this initially; after one trade, I realized the fees ate up a significant portion of the profit.
The costs of perpetual contracts mainly fall into two categories: trading fees and funding rates. First, let's talk about trading fees, which are the most straightforward costs. Maker orders usually cost 0.02%, while market orders (taker) are 0.05%. Many people don't understand the difference; simply put—placing an order manually at a specifi

Recently, many people have been discussing SOL, all saying it's forming an ascending flag pattern, but looking at the chart, something still feels off.
Honestly, a descending channel and an ascending flag look quite similar, and if you don't carefully analyze the chart features, it's easy to get confused. The recent drop yesterday, many still insisted on the logic of an ascending flag pattern, but the problem is, SOL is actually still oscillating within a descending channel.
This is a common trap in technical analysis. Just because a chart looks similar doesn't mean it's the same thing; tradin

Recently, I talked with friends about cross-border payments and found that many people actually can't tell the difference between offshore RMB and onshore RMB. I only recently figured it out myself, so I might as well organize my thoughts.
Speaking of which, this matter starts with the openness of China's capital account. Because the central bank has strict control over the domestic financial markets, two systems have emerged—one used domestically, and one used offshore.
Onshore RMB is the CNY we usually use domestically. The RMB traded at the Shanghai Foreign Exchange Trading Center is this t

Recently, many beginners have shown interest in leveraged trading, and I think it's necessary to have a good discussion on this topic. To be honest, leveraged trading is like a double-edged sword; if used well, it can amplify profits, but if used poorly, it can lead to liquidation.
In simple terms, leveraged trading means borrowing money to trade. You put up a portion of your capital as margin, and the trading platform or other traders lend you the remaining funds, allowing you to control a larger position with less money. For example, with 10:1 leverage, investing $10k allows you to trade $10

Recently, I’ve noticed that many traders are still stubbornly relying on various technical indicators, staring at live streams waiting for master tips, but ending up with heavy losses. I think, rather than wasting time like that, it’s better to calm down and learn naked candlestick trading, also known as price action trading.
Naked candlestick trading sounds mysterious, but it’s actually just judging market direction by observing the price movement structure on the candlestick chart, without relying on complicated technical indicators. Of course, this doesn’t mean completely ignoring other too

Recently rereading some classic works, I find that the ideas of Hayek, this great economist, are deeper than I imagined. When he took the Nobel Prize in Economics podium in 1974, no one expected that four years later something would happen that sent shockwaves through academia—he publicly invited everyone who questioned him to debate in Paris, and yet not a single person responded. Behind the seemingly calm silence lies a deeper truth: refuting Hayek was not a defeat of him personally, but a defeat by reality itself.
The intellectual legacy he left behind is razor-sharp; every viewpoint slices

Recently, I’ve been chatting with some trading experts and discovered that their secret weapon for identifying trading opportunities is harmonic patterns. Honestly, learning this stuff is quite challenging, but once you master it, your win rate can reach 70-80%, which is already pretty good for traders.
The core logic of harmonic patterns is actually very simple: using Fibonacci sequences and specific wave combinations to find potential reversal zones in the market. Today, I want to delve into these common harmonic patterns, hoping to help everyone understand this trading system better.
First

Recently, I’ve seen people asking about the “drawing door” pattern, so I’ll lay out what’s going on clearly.
To be honest, this kind of market action doesn’t exist in the stock market or forex—it’s unique to the crypto world. You’ll see the price surge sharply in a short period, then trade sideways, and afterwards it will crash so hard that you start to doubt you’re seeing things right. From the candlestick chart, it looks as if someone used a pen to draw a door frame, so people in the community call it the “drawing door” pattern.
Why does this happen again and again? The root cause is market

Recently, I’ve been looking into Bitcoin’s history and found a pretty interesting phenomenon. There’s a website called “Bitcoin Is Dead,” which specifically records the statements of famous people who predicted Bitcoin’s collapse. Just among economists, Peter Schiff has claimed Bitcoin has died 18 times, Nobel laureate Krugman and JPMorgan CEO Dimon are also on the list. But none of these predictions have come true.
Last year, Bitcoin hit a new high, then adjusted to its current price, but the key question is: what supports it to keep rising from the “death predictions” time and again? This in

The Japanese woman Kokuha Rei, who claims to be from 2058, has spoken again, and recently she has stirred up no small amount of commotion across social media. When it comes to her track record, she says she predicted things like the number of gold medals at the Tokyo Olympics, the Nikkei index’s plunge, and Shinzo Abe stepping down—no wonder so many people treat her as a sort of divine figure.
But this time, Kokuha Rei’s prediction focus shifted to cryptocurrencies. She claims that she once used her father’s account to buy in large quantities more than 1,400 ETH at the end of 2019, and then bu
