In leveraged trading, choosing the correct margin mode is like selecting a container for your risk tolerance — one that holds a smaller amount, and one that holds a larger amount. The two margin configurations, cross margin and isolated margin, determine how you allocate funds during trading and your loss boundaries.
Isolated Margin Mode: The Choice of Risk Isolation
What is Isolated Margin?
In isolated margin mode, the margin for each position is independent and fixed. When you open a position, the leverage you set determines how much margin that position requires. Simply put, no matter how much that position loses, it can only lose the margin you have locked in for it individually.
The calculation is straightforward:
Isolated Margin = Position Size × Entry Price ÷ Leverage
For example: You buy 0.1 BTC of BTCUSDT contract at a price of 50,000 USDT, with leverage set to 25x, then the isolated margin = 50,000 × 0.1 ÷ 25

As Bitcoin prices soar, the identity of Satoshi Nakamoto and the mystery of the billionaire have once again become the focus. Since 2011, the large amount of Bitcoin he owns has never been moved, sparking curiosity about the reason behind it. Analysis suggests that Satoshi Nakamoto may be older, and the mystery of his identity remains unsolved. As Bitcoin becomes more popular, its cultural significance deepens, becoming a symbol of protest and innovation.

The surge in cryptocurrency has brought a new online threat—mining viruses are quietly invading millions of computers worldwide. If you've recently noticed your device running slower or suspect that "your device is being mined," this guide can help you uncover the truth.
Is your computer sending out warning signals? First, check for these symptoms:
Many people ask, "How do I know if my device is being mined?" Actually, your computer will give some obvious signs.
A significant drop in performance is the most common indicator. Even opening a single browser tab can cause noticeable lag. Programs launch slowly, and even moving the mouse can experience delays.
Abnormal fan noise is another warning sign. Your laptop or desktop may emit continuous high-pitched sounds, and the device may become hot to the touch. This indicates that the CPU or GPU is performing high-intensity calculations—likely mining cryptocurrency for hackers.
Power consumption skyrocketing

Recently, the USD to JPY exchange rate has reached 4.85, up more than 8% from 4.46 at the beginning of the year. Many people are starting to seriously consider exchanging for Japanese Yen. Whether planning a trip to Japan, purchasing on behalf of others, or looking to allocate funds into this major safe-haven currency, the key question remains the same—how to exchange at the lowest cost?
We have summarized the four most mainstream currency exchange channels in Taiwan, using real market prices to reveal the hidden costs of each method, ensuring you don't spend a single unnecessary dollar.
Why focus on the Yen now?
When it comes to foreign currency exchange, many people's first reaction is the Yen, but the real reasons are much more complex than just "wanting to visit Japan."
Daily life aspect: Most businesses in Japan still rely on cash payments (credit card penetration is only 60%), and activities like purchasing on behalf of others, online shopping, studying abroad, and part-time work all require frequent use of Yen.
Financial investment aspect: The Yen, along with the USD and Swiss Franc, is one of the three major safe-haven currencies. Whenever the global market experiences volatility, capital

Nanya Technology (2408) became the market focus today. Driven by optimistic expectations from Micron, the stock price surged to a historic high of 190 NT dollars during the trading session, closing at 189 NT dollars, a single-day increase of 7.08%, with trading volume also expanding to 117,000 shares. This wave of growth is not a fleeting phenomenon; it conceals a deep restructuring of the supply and demand landscape in the memory industry.
1B process enters capacity release phase, ASP elasticity creates a rare ten-year record
The core driver behind Nanya Technology's recent rise is the official profitability of its self-developed second-generation 10-nanometer class process (1B). According to the latest statistics, products using the 1B process already account for over 30% of Nanya Technology's bit output in 2025, with 16Gb DDR5 5600 specifications supplied stably, and even higher-speed 6400 MT/s versions in the verification sprint stage.
While competing with international giants, Nanya Technology successfully maintains its DDR4 pricing advantage and narrows the gap in DDR5 process落

As of December 2025, the Taiwanese dollar has risen to a critical level of 4.85 against the Japanese yen. Compared to 4.46 at the beginning of the year, the yen has appreciated by 8.7%. This market trend has attracted many people to seriously consider currency exchange or investing in yen. But the question is: how exactly should one exchange currency to avoid losing money to exchange rate spreads and fees?
Why has exchanging yen become a hot topic now?
The yen is not just pocket money for travel; it is also one of the world's three major safe-haven currencies. From the perspective of Taiwanese daily needs, whether it's shopping in Japan, purchasing via proxy, studying abroad, or seeking hedging tools against Taiwan stock market fluctuations from an asset allocation standpoint, the yen plays an important role.
Especially against the backdrop of increasing pressure for the Taiwanese dollar to depreciate, many investors have started allocating part of their funds into yen, hoping to benefit from currency appreciation and low-interest arbitrage. Data shows that Taiwan's currency exchange demand in the second half of the year has grown by 25% compared to the first half, mainly driven by the recovery of tourism.

When it comes to investment scams, one name always comes up—Ponzi schemes. This ancient and stubborn form of fraud has been playing out in financial markets for over 100 years, from Wall Street to blockchain. No matter how times change, it reappears in different forms, and the list of victims continues to grow.
How does a Ponzi scheme work? Starting with an Italian con artist
This legendary financial scam originated from an Italian-American con artist named Charles Ponzi. In 1903, after sneaking into the United States, he went through various ups and downs, working as a painter, laborer, and more. He was imprisoned in Canada for forgery and detained in Atlanta for human trafficking. After a series of failures, Ponzi discovered the fastest way to make money—financial fraud.
In 1919, just after the end of World War I, the global economy was in chaos. Ponzi saw this opportunity and claimed he could buy European postal notes and resell them to the United States.

When investors cannot find their desired assets on mainstream exchanges, the over-the-counter (OTC) market becomes another window of opportunity. As an essential part of the global financial system, OTC markets attract countless investors with their flexibility and diversity, but hidden risks should not be overlooked. What exactly is over-the-counter trading? How does it work? What are the fundamental differences from on-exchange trading? This article will provide an in-depth analysis.
Core Definition and Characteristics of Over-the-Counter Trading
Over-the-counter (OTC) trading refers to the behavior of investors bypassing centralized exchanges and directly buying and selling securities and financial products through decentralized channels such as banks, brokerages, phone, and electronic systems. This type of trading is also known as "over-the-counter trading" or "OTC trading."
Unlike prices generated by unified market auction in on-exchange trading, OTC trading prices are entirely negotiated and determined by both parties. The counterparties are diverse — they may be

Are you aware of the hidden costs of investing in stocks?
Many investors focus only on stock price fluctuations when buying and selling stocks, but they overlook the various fees incurred during the trading process. In fact, to accurately calculate whether a stock has truly yielded a profit, it is essential to understand the cost structure involved in each transaction.
The costs associated with stock trading mainly consist of broker commissions and exchange fees. These fees vary significantly depending on the trading region. For example, in the Taiwan market, investors need to pay a 0.1425% brokerage commission and a 0.30% transaction tax; whereas in the US stock market, due to different trading methods, the cost structure is entirely different.
Taiwan Stock Market: Cost Structure and Calculation Methods
When trading in the Taiwan stock market, the main costs include two items: brokerage commissions and transaction taxes. Commissions are charged at the time of purchase, while transaction taxes are only levied when selling.
Cost Calculation Formula:
- Purchase Cost = Transaction

The NT dollar to Japanese Yen exchange rate has reached 4.85, up from 4.46 at the beginning of the year, an accumulated appreciation of 8.7%. Many people are starting to consider exchanging for Yen. But do you know? Just choosing the wrong exchange channel can cost you an extra 1,500 to 2,000 NT dollars on a 50,000 NT dollar transaction. Today, we'll help you calculate the latest exchange rates clearly.
Four ways to exchange Yen, with significantly different costs
Many people think that exchanging Yen is as simple as going to a bank counter to withdraw cash, but in fact, the exchange rate and handling fees vary greatly across channels. Based on the bank rates as of December 10, 2025, we analyze each method.
Method 1: Direct cash exchange at the counter, the most traditional but most expensive
Bringing cash NT dollars to the bank counter or airport to exchange for Yen cash is the most common method. However, the "cash selling rate" is usually 1-2% worse than the spot market rate, and some banks also charge handling fees. Exchanging 50,000 NT dollars this way could result in a loss of 1,500 to 2,000 NT dollars.

Futures trading may seem complicated, but at its core, it revolves around five key steps: "Open, Hold, Close, Explode, Turn." If you don't understand these concepts clearly, it's easy to suffer losses in the market. Today, from a trader's perspective, we'll analyze each step one by one.
Understand the Beginning and End of Trading
Opening and closing positions are two ends of trading, and both are indispensable.
Opening a position means you decide to enter the market by buying or selling a certain commodity, stock, or futures contract. At this point, you have a position, but you haven't yet confirmed profit or loss—because the market is still fluctuating. Only when you close the position (end this trade by selling all or part of it and buying back, or vice versa) can you lock in the final profit or loss.
For example, you are optimistic about Apple stock AAPL, so you buy 100 shares. This is opening a position. Afterwards, the stock price may go up or down, but as long as you still hold these 100 shares, the position remains "unclosed." Only when you sell all 100 shares does the trade conclude.

Why Do Non-Farm Payrolls Data Influence Global Financial Markets?
To seize opportunities in the financial markets, you first need to understand a key indicator—the Non-Farm Payrolls (NFP) data. This report, released monthly by the U.S. Bureau of Labor Statistics, has long been a closely watched barometer among global investors. Why? Because it directly reflects the health of the U.S. economy, and when the U.S. economy moves, the entire global market tends to shake.
When the Non-Farm Payrolls data perform strongly, the U.S. stock market may rise, the dollar may appreciate, and even cryptocurrency prices can be affected. Conversely, if the data fall short of expectations, investor confidence can be undermined, leading to shifts in capital flows. That’s why many traders prepare thoroughly before the NFP release.
What Are Non-Farm Employment and Related Indicators?
Non-Farm Payrolls data are actually divided into two levels of indicators, which investors need to understand separately.

The True Reasons Behind the South African Rand's Continued Decline
In the foreign exchange market, the performance of the South African Rand (ZAR) has long been a headache for investors. Unlike other emerging market currencies, the Rand is not simply falling but oscillating within a long-term depreciation channel. Behind this are complex economic and political factors driving the trend.
The South African Rand is defined by the market as a "risk currency," meaning that when the global financial environment becomes uncertain, capital tends to withdraw from South Africa. Over the past few years, aggressive Federal Reserve rate hikes, global banking crises, and recession fears have all put immense downward pressure on the Rand.
Core Drivers Behind the South African Rand's Decline
Government Debt and Interest Rate Dilemma
The latest budget data released by South Africa's Treasury shows that the government deficit is widening, and the debt burden continues to grow. More concerning is that core inflation data has started to decline, indicating that the South African Reserve Bank may move towards cutting interest rates.

Key Dates for CPI Announcements and Market Reactions
The US Consumer Price Index (CPI), one of the most closely watched economic indicators worldwide, directly influences financial market volatility depending on its release timing. CPI is typically announced on the first business day of each month or the nearest business day, with specific times varying due to daylight saving time—at 20:30 Taiwan time during daylight saving time, and at 21:30 during standard time.
Why are markets so sensitive to CPI announcement times? Because US CPI data is released before the PCE data, which is the primary reference for the Federal Reserve's policy decisions. Every decision made by the Fed ultimately impacts global asset prices, so investors tend to stay highly alert around CPI release times.
The full 2024 CPI announcement schedule (Taiwan time) is as follows: January 11 at 21:30, February 13 at 21:30, March 12 at

Overview of Currency Symbols Used in Over 30 Countries
In international financial transactions, quickly identifying different countries' currency symbols is crucial. Symbols not only save the hassle of writing out full names but also allow traders to grasp price information instantly. For example, seeing "$" usually makes us think of the US dollar, but in fact, it is used by over 30 countries; similarly, "￥" represents different currencies in Japan and China.
Below is a quick reference table of major trading currency symbols:
| Continent | Country | Currency | Code | Symbol |
|------------|---------|----------|-------|--------|
| Americas | USA | US Dollar | USD | $ |

On December 10, 2025, the exchange rate of the New Taiwan Dollar (NTD) against the Japanese Yen (JPY) rose above 4.85, up 8.7% from 4.46 at the beginning of the year. For many people, this is a good time to exchange for Yen—whether for traveling abroad or for asset allocation while the NTD depreciates. But the question is, what is the best way to exchange to minimize costs?
Why is it worth exchanging for Yen?
In Taiwan's foreign currency market, the Yen has always been favored. This is not only because of the popularity of travel to Japan but also due to the Yen's intrinsic investment value.
As one of the world's three major safe-haven currencies (the other two are the US Dollar and Swiss Franc), the Yen often appreciates countercyclically during global market turbulence. During the Russia-Ukraine conflict in 2022, the Yen appreciated by 8% in a single week, helping safe-haven investors cut losses when the stock market fell by 10%. For Taiwanese investors, holding Yen is not just for leisure but also for hedging against fluctuations in the Taiwan stock market.
From an interest rate perspective, Japan's long-term
