Ethereum, as the world's largest blockchain application platform, aggregates over 4,000 DApps, maintaining a long-term stable position. However, the rise of Polkadot is gradually changing the market landscape, with its innovative cross-chain architecture and excellent performance metrics making it a strong competitor for the next-generation public chain.
What is DOT? An Introduction to the Polkadot Ecosystem
DOT is the native token of the Polkadot blockchain ecosystem, also known as Polkadot Coin. As the governance and operational token of the Polkadot network, DOT carries the economic incentive mechanism of the entire multi-chain system.
According to the latest data, the current price of DOT is $2.16, with a circulating supply of 1,652,573,526 tokens, and a market capitalization of approximately $3.56 billion. Compared to its all-time high of $54.98, it is currently at a relatively low position, having decreased by 2.30% in the past 24 hours.
Polkadot differs from single-chain architectures in that

What exactly are Fully Settled Shares?
In the Taiwanese stock market, fully settled shares are a special trading system. When a listed company experiences poor management, financial difficulties, or is involved in major violations, causing its net asset value per share to fall below the face value of 5 yuan, the stock will be placed on the fully settled shares list by the regulatory authorities. This means that stock investors must pay the full amount upfront at the time of purchase and cannot use credit trading tools such as margin or short selling.
Do Fully Settled Shares Have a Chance to Turn Around?
Being designated as fully settled shares is not a lifelong status. When the company's operations improve and financial indicators get better, there is a possibility to revert to regular stock trading. The main conditions for recovery include:
Requirements for listed companies: Continuous two-quarter net asset value per share exceeding 5 yuan, and shareholder equity exceeding 300 million yuan for two consecutive quarters.
Requirements for OTC companies: Net asset value per share exceeding 5 yuan in a single quarterly financial report, and growth in shareholder equity.
Once the conditions are met

The Federal Reserve (Fed) is expected to cut interest rates in December, leading to a significant shift in global capital flows. The three major institutional investors collectively bought a net of 19.117 billion yuan today, hitting a recent single-day high and driving the Taiwan Weighted Index up by 322.89 points, a 1.15% increase to stand at 28,303.78 points. Trading volume expanded to 424.744 billion yuan. But is this rally a sustained bullish trend or a sign of short-term speculative overheating?
Dollar Weakness Triggers Major Capital Shift in Asia
First, it is worth paying attention to the synchronized performance of Asian markets. The Nikkei 225 rose 1.2% to 39,800 points, South Korea's KOSPI increased 0.8% to 2,650 points, China's Shanghai Composite rose 0.3% to 3,150 points, and India's Nifty 50 gained 0.9% to 24,200 points. This is not a coincidence but a collective action driven by foreign capital inflows exceeding 15 billion USD this week.
The US dollar index fell to 102.5, indicating weakness

When it comes to technical analysis, many novice traders have heard of the KD line but often don't know what it is used for. In fact, the KD line (Stochastic Oscillator) is a powerful tool for judging entry and exit points. Used properly, it can help you avoid getting caught at high prices or selling at lows. Today, we'll analyze this indicator in depth from a practical perspective.
What exactly is the KD line? Why use it?
The KD line, officially known as the "Stochastic Oscillator," was created by American analyst George Lane in the 1950s. Its core purpose is to capture changes in price momentum and trend reversals.
Imagine the K line as a敏锐的猎犬, with a keen sense of smell and quick reactions; the D line is a稳重的管家, following more slowly but reliably. The interaction between these two lines helps traders determine whether the market is overbought, oversold, or about to reverse.

The rate hike arrow is on the string, but the market is divided into two camps
Bank of Japan Governor Ueda Kazuo will make a statement next week. The December 19 interest rate decision has already become a "time bomb" for the global financial markets. The market unanimously expects a 25 basis point hike to 0.75%, creating a 30-year high in Japan, but the real concern lies in the central bank's attitude towards the subsequent path—whether it will continue to be aggressively hawkish or adopt a more cautious, dovish stance.
The rate hike itself has been fully digested; the question is about the extent. Nomura Securities issued a warning, stating that the current terminal rate is priced to rise to 1.0% by September 2026, which may be overly optimistic. Conversely, analysis within U.S. banks and the Bank of Japan indicates that the natural rate is rising, and the lower bound of the neutral rate is likely to be adjusted upward from 1.0%. This suggests that hawkish advocates believe there is much more room for rate increases than previously expected.
Arbitrage traders face a "life-and-death moment"
Why will this wave of rate hikes trigger panic among global capital?

Behind the Stock Price Surge: HBM's Capacity Grab Sparks Major DDR4 Shortage
Micron recently released an optimistic outlook, instantly igniting bullish sentiment across the entire memory sector. Powerchip (2408) followed with a surge of buying interest, reaching a new high of 190 NT dollars during the trading session, ultimately closing at 189 NT dollars, a daily increase of over 12 NT dollars, up 7.08%. Trading volume also expanded by more than 117,000 shares.
This rally is far from a false alarm. The real market driver comes from an "urgent" capacity shift—three of the world's largest memory manufacturers are reallocating DDR4 capacity at an unprecedented speed to seize the high-bandwidth memory (HBM) market for AI servers. Changxin Storage reportedly plans to slash DDR4 monthly capacity by half in 2026 to 10,000 units, and Micron's Crucial brand also announced it will cease some DDR4 production lines in early 2026. Just a few news reports have completely rewritten the entire market supply landscape.

The strong performance of US technology stocks has injected a powerful boost into the Taiwan stock market. Today, the Taiwan stock market continued its bullish momentum, opening higher and closing at 28,310.47 points, up 160.83 points, a gain of 0.57%. The most eye-catching among them is undoubtedly the heavyweight TSMC (2330). Driven by market optimism, its stock price surged by 25 NT dollars to 1,490 NT dollars, a single-day increase of 1.71%, making it the absolute main player during this rapid rise.
Technology stocks rally, foreign investors can't resist returning to the market
The S&P 500 index has been trending upward for three consecutive days, with the Nasdaq index rising in tandem. Nvidia and TSMC's American depositary receipts (ADRs) respectively increased by 1.49% and 1.50%. This rally has indeed stimulated investor buying enthusiasm. After opening at 28,253 points, the Taiwan stock market briefly touched a high of 28,350 points during the session. Although there was some correction pressure at high levels, the index still remained firmly above the critical support level of 28,300 points.

When it comes to Return on Investment (ROI), many people's first reaction is a bunch of complicated mathematical formulas. But in reality, as long as you understand the core logic of calculating returns, anyone can quickly evaluate their investment performance and make more rational decisions.
What exactly is ROI? Why are investors talking about it?
Return on Investment (ROI) simply means: how much profit you get in exchange for how much money invested. Expressed as a percentage, it measures how much return can be generated from the invested capital.
This metric has a wide range of applications—individuals use ROI to judge whether an investment is worthwhile; corporate management evaluates project efficiency with ROI; e-commerce operators measure advertising effectiveness using ROI. It can be said that ROI is one of the most important reference indicators for investment decisions.

Why Have Defense Stocks Become the New Hot Topic?
The current global situation is changing rapidly. The Ukraine war and frequent conflicts in the Middle East have led countries to reassess their national defense capabilities. Unlike the large-scale manpower-intensive wars of the past, modern military confrontations increasingly emphasize technological applications—drones, precision missiles, and information warfare have become key to victory.
There is a strong economic driving force behind this trend. According to the latest data, global military spending continues to rise. Key regions such as China, Taiwan, and the United States are increasing their defense budgets. Many companies are seizing this opportunity by providing cutting-edge defense technologies and securing substantial government contracts.
In an era of declining birthrates, countries prefer to spend money on high-tech weapon systems rather than significantly expanding their military personnel. This shift is a major positive for arms manufacturers—meaning that orders will be sustained over the long term, and revenue will grow steadily.

Entering the Hong Kong stock market, mastering trading hours is the first essential lesson. Whether you are a beginner or an experienced trader, understanding when the Hong Kong Stock Exchange opens and closes, and how to plan your trading strategies, directly impacts your profits. This article will provide a comprehensive analysis of each trading session, market holidays, and practical tips for 2025.
Basic Background of the Hong Kong Stock Exchange
As an Asian financial hub, HKEX (Hong Kong Exchanges and Clearing Limited, stock code: 0388.HK) is the only securities exchange in Hong Kong and ranks among the top ten globally and the top three in Asia. It not only offers stock trading but also covers options, futures, derivatives, and other financial services.
Since its establishment in 1989, HKEX has repeatedly ranked first globally in IPO fundraising over the past decade and is one of Asia’s most active capital markets. Its main subsidiaries include the Stock Exchange, Futures Exchange, and Central Clearing Company, each performing their respective roles to ensure the safe operation of the market.

Shipping stocks have recently experienced intense volatility, rapidly declining from peaks in 2022, with the market capitalization of major global shipping giants significantly shrinking. The main reasons include a slowdown in global trade activity, Federal Reserve interest rate hikes, geopolitical shocks, and increased environmental protection costs. Investors should pay attention to large enterprises and the age of their fleets, proceed with caution in their allocations, and seize future rebound opportunities.

When it comes to investing in the US stock market, many people have heard of one term—Quadruple Witching Day. As this date approaches, the market is often filled with warnings: prices may fluctuate significantly, beware of margin calls, and market makers may start to manipulate the market. But what is the root cause of all this? Why do the entire market experience such drastic changes just because of a few specific dates?
The Truth About Quadruple Witching Day: A Market Feast of Derivatives Expiration
The essence of Quadruple Witching Day is quite simple—it is the day when the four major types of American derivatives settle simultaneously. These four categories include single-stock futures, single-stock options, stock index futures, and stock index options. Every year, on the third Friday of March, June, September, and December, these contracts all expire at the same time.
Why is it called "Quadruple Witching"? Because an invisible force influences prices on this day—when futures contracts approach their expiration date, futures prices are forced to converge with the spot prices. This non-fundamental-driven convergence can lead to increased volatility and trading volume, creating a market spectacle.

It's only the third quarter of 2025, and international spot gold has already repeatedly broken historical records. From the beginning of the year at $2,690 per ounce, it surged to break through the $4,300 mark in October, an increase of over 56%. Behind this market trend reflects profound changes in the global economic landscape—central bank accumulation, geopolitical turmoil, and a weakening dollar—these factors are reshaping the investment value of gold.
But here’s the question: over the past 50 years, gold prices have increased 120 times, will such a miracle repeat in the next 50 years? If you want to invest in gold now, how should you judge?
Gold, is it really a good investment?
Let's look at the data. Starting from 1971, when the dollar was decoupled from gold, gold has increased by 120 times. During the same period, the Dow Jones Industrial Average rose from 900 points to 46,000 points, an increase of about 51 times. At first glance, gold has outperformed, but this calculation has a fatal flaw—gold price movements are not always a straight line.

The Correlation Logic Between Copper Prices and Copper Stocks
In this recent rally, both spot copper and copper stocks have performed remarkably well. Taking Freeport-McMoRan (FCX), the world's largest copper producer, as an example, its stock has surged over 30% in just 45 days, while international copper prices have increased by 17% during the same period. This reflects a simple yet effective investment logic: the movement of copper stocks is highly synchronized with copper price fluctuations.
Why is this the case? The reason is straightforward—core revenue for copper mining companies comes from the extraction and sale of copper. When copper prices rise, it directly boosts the company's gross profit margin, causing the stock price to rise accordingly. If you compare the trend chart of copper mining ETFs (COPX) with LME copper prices, you'll find that the two lines are basically overlapping, which is the best proof.
Breaking Down the Copper Industry Chain: Investment Opportunities Vary Significantly at Different Stages
To truly understand copper stock investment, you must first understand the industry structure of copper. From mines to end-user products, copper

When it comes to "Ponzi schemes," many people are itching with hatred—because they exploit human weaknesses, weave dreams of wealth, and sweep away victims' hard-earned money. Interestingly, most scams in the financial fraud field can be traced back to some variant of this pattern. Although we've all heard of the name, few truly understand its origins, operational logic, and prevention methods. Today, we will delve into the evolution of this century-old scam, analyze some iconic cases, and explore how to make your money safer.
From an Italian immigrant to the dark legend of the "Father of Finance"
The name "Ponzi scheme" originates from Charles Ponzi, an Italian-born individual. The operational logic of this type of scam seems simple: promise investors low-risk, high-return investment opportunities to attract their funds. But the "investment returns" here are not derived from real business or assets.

Want to improve your success rate in stock or crypto asset trading? Learning how to use the KDJ indicator is a must for many retail investors. This technical tool, known as one of the "Three Treasures of Retail Investors," how does it help traders identify turning points amid market volatility? This article will systematically explain the core principles of the KDJ indicator, practical applications, and common pitfalls.
The essence of the KDJ indicator: The secret of three lines
The stochastic indicator KDJ consists of three curves: K line (fast line), D line (slow line), and J line (direction line). They compare the relationship between the highest price, lowest price, and closing price over a period to determine whether the market is overbought or oversold.
Simply put:
- K and D values: reflect overbought/oversold levels (above 80 is overbought, below 20 is oversold)
- J value: measures the divergence between K and D, with higher sensitivity
The crossovers and divergences of these three lines are the most critical buy and sell signals in KDJ indicator usage.

Cryptocurrencies have evolved from niche investment assets to an important option for asset allocation, especially against the backdrop of increasing global economic uncertainty. However, with thousands of virtual currencies available, investors often face a dilemma in choosing. This article will start from the actual market situation to help you understand how to select, how to invest, and which virtual currencies are currently the most worth paying attention to.
Market Logic You Must Know Before Investing in Virtual Currencies
Regarding virtual currency investment, there is a classic saying circulating in the industry: "Buy altcoins in a bull market, buy mainstream coins in a bear market." The investment wisdom behind this phrase is worth a deep understanding.
Why are altcoins suitable in a bull market? Because altcoins often see more astonishing gains. When market sentiment is high, funds flow into these high-risk assets seeking maximum returns. But the price volatility is intense, and even a slight disturbance can lead to a crash.
Why do investors return to mainstream coins in a bear market? When the market enters a downward cycle, investors start seeking stability. Mainstream coins, due to their large market capitalization,

In recent years, the global gold market has continued to heat up. According to data from the World Gold Council, central banks have increased their gold holdings for three consecutive years, reaching a new high in half a century. For Taiwanese investors, spot gold is gradually becoming one of the options for asset allocation. However, many people are still unfamiliar with "spot gold." What exactly is it? How can one participate? This article will provide a detailed analysis.
What is Spot Gold? How Does It Differ from Physical Gold?
Spot gold (also known as "international gold" or "London gold") is a virtual trading product based on XAUUSD, tracking the current international gold price in real time. Unlike purchasing physical gold bars or coins, spot gold is a paper-based transaction. Investors only need to buy and sell through electronic platforms without involving physical delivery.
The main differences are as follows:
Physical Gold: Buying gold bars or coins for long-term preservation, with higher costs (including storage and appraisal fees). It offers strong hedging effects but is less liquid than spot products.
