The U.S. Congress has recently taken new actions. According to multiple media reports, U.S. Representative Sean Casten is pushing a new legislative proposal targeting tools like Crypto Tumbler / Crypto Mixer, which are being abused by criminals for money laundering. This move signals that U.S. regulation of the crypto industry will enter a new phase.
How does a Crypto Tumbler / Crypto Mixer work? An infographic to understand the principles of anonymous transactions
Imagine a Crypto Tumbler / Crypto Mixer as a giant "stirring machine" for cryptocurrencies. The specific process is: first, investors transfer their crypto assets into the mixing service; then, the service combines funds from multiple users; finally, the system randomly and in varying amounts disperses the mixed funds into different wallet addresses.
The clever part of this process is that—once the funds are mixed and redistributed—the original transaction records and the final recipient addresses are thoroughly untraceable, achieving

Weak employment data, December rate cut expectations rise
The US labor market has recently underperformed expectations. In October, US companies announced layoffs of 153,000 people, a month-on-month increase of 183%, the highest single-month record since 2003; at the same time, the September non-farm unemployment rate rose to 4.4%, a 175% increase compared to the same period last year. These data fully indicate that the US employment market is under pressure.
According to CME's FedWatch rate tool, the market's probability of a 25 bps rate cut by the Federal Reserve in December is close to 85%. The Federal Reserve's Beige Book also revealed that the government shutdown has negatively impacted consumer shopping, leading to a further decline in consumer spending. Against this backdrop, rate cut expectations have become a market consensus.
The US dollar is under pressure, 10-year US Treasury yields fall below 4%
Affected by rate cut expectations, the 10-year US Treasury yield has fallen below the 4% key level, which has a clear impact on gold priced in US dollars.

As of December 10, 2025, the Taiwanese dollar has reached 4.85 against the Japanese yen, hitting a new high this year. Starting from 4.46 at the beginning of the year, the yen has appreciated by over 8% within the year. For investors looking to exchange currency, this is an unmissable opportunity. But what's the most cost-effective way to exchange? We will explain the latest four currency exchange channels once and for all, helping you save unnecessary expenses.
Why exchange yen now?
The yen is no longer just pocket money for travel; it has three layers of value.
Travel and daily consumption
Shopping in Tokyo and Osaka, skiing in Hokkaido, vacationing in Okinawa—most Japanese merchants still prefer cash (credit card penetration is only 60%). Purchasing agents, online shopping, studying abroad, and part-time work all require direct settlement in yen.
Hedging asset status
The yen ranks among the world's three major safe-haven currencies (along with the US dollar and Swiss franc). During the Russia-Ukraine conflict in 2022, the yen appreciated by 8% in a week, effectively buffering stock market declines. For Taiwanese investors, exchanging for yen is equivalent to adding to the Taiwanese stock market.

Between 2024 and 2025, gold prices are reaching a new peak amid global economic uncertainties. After breaking the $4,400 mark in October to set a new record, gold prices have slightly retreated but have not dampened market enthusiasm. Investors are generally concerned: Will gold prices continue to rise today? Is it too late to enter the market? To answer this question well, one must first understand the underlying logic driving the current upward trend in gold prices.
Why is gold (XAUUSD) expected to rise in 2025?
According to data from Reuters, the increase in gold from 2024 to 2025 has approached the highest levels in nearly 30 years, surpassing the 31% rise in 2007 and the 29% performance in 2010. This upward movement is not unfounded but the result of multiple factors stacking up.
First, geopolitical policy uncertainties are boosting safe-haven demand. The series of tariff measures introduced after Trump took office directly ignited the gold rally at the beginning of the year. Market risk aversion sentiment has increased, and gold

Mastering the currency symbols and English codes of various countries is very important for forex trading and international payments, as it can improve the speed of information interpretation. Currency symbols such as "￥" and "$" may cause confusion, and different symbols have different meanings in trading, including Thai Baht and Bitcoin. Familiarity with major global currencies and their quick input methods is the foundation for effectively executing trading strategies.

Taiwan stocks hover around 28,000 points, with tech stocks showing a clear slowdown in upward momentum. However, an interesting phenomenon has emerged in the market: large sums of capital are quietly shifting from high P/E electronic stocks to the financial sector. This is not a coincidence but a typical capital rotation signal.
Compared to a fixed deposit annual interest rate of 2%, financial stocks can reliably offer a cash dividend yield of 5-7%, with potential for stock price rebound. This incentive is strong enough. The question is: is it really the right time to enter? This article helps you analyze and uncover the core logic behind investing in financial stocks.
Why are financial stocks suddenly gaining popularity now?
Valuation Dislocation Effect
The main players in this round of global market rally are electronic stocks, especially those related to AI concepts. But here’s the problem—P/E ratios have already surged above 30, yet profit growth has not returned to last year's explosive levels. In comparison, large bank stocks still have P/E ratios around 10-12, while tech stocks are generally 2-3 times higher. When stocks rise too much, inevitably some investors will take profits, and capital

The opening hours of the US stock market vary with the seasons and are crucial for investors in Taiwan and Hong Kong. In winter 2025, Taiwan's trading hours are from 22:30 to 5:00, and Hong Kong's are from 21:30 to 4:00. The US stock market has three major exchanges, and trading rules should also be noted. Investors should pay attention to market holiday schedules and the opening times of major global stock markets to avoid trading disruptions caused by time zone differences.

Stock investment is not limited to traditional buy-and-hold strategies; margin financing and securities lending provide investors with diversified arbitrage opportunities. Margin financing amplifies returns through borrowed funds but requires attention to interest costs and risks, such as forced liquidation. Securities lending allows investors to profit during declines but faces risks related to usage periods and maintenance margins. Mastering tools, selecting targets, and risk management are key to success.

1. Understanding the Nature and Core Characteristics of Futures
Futures are standardized contract transactions where both parties agree to buy or sell an asset at a predetermined price at a specific future date. This concept sounds simple, but the risks and mechanisms involved are far more complex than spot trading.
The underlying assets for futures trading include:
- Stock indices (e.g., Taiwan Weighted Index)
- Foreign exchange rates
- Precious metals (gold, silver, copper)
- Energy commodities (crude oil, natural gas)
- Agricultural products (wheat, corn, soybeans)
- Bonds and interest rate products
The biggest feature of the futures market is the use of margin trading. Investors do not need to pay the full contract amount; they only need to deposit a certain percentage of the margin to control a position much larger than their capital. This leverage characteristic makes futures a high-risk, high-reward investment tool.
2. Why Are Futures So Attractive to Investors? Understanding the Advantages of Futures
Compared to stock investments, futures trading has several clear advantages.

If you're overwhelmed by dense technical indicators when looking at candlestick charts, don't worry—today we're going to discuss the Stochastic Oscillator, one of the easiest tools to get started with. Simply put, it helps you identify when a stock is overbought or oversold, enabling you to make the right decision at critical moments.
What is the core logic of the KD indicator: What exactly is it measuring?
The KD indicator was introduced by American technical analyst George Lane in the 1950s. The word "Stochastic" in its name actually refers to tracking the relative position changes of the stock price over a period of time. Imagine the stock price rising from a low point to a high point over 14 days—where does today's closing price fall? Is it just coming up from the low, or is it already near the high? The KD indicator answers this question using a scale from 0 to 100.
This indicator consists of two lines, each

Gold prices surged past the $4300 mark in 2024, and the market's outlook remains divided. Many investors share the same question—how long can this gold rally last? Is it still worth entering now?
To answer this question, we first need to understand the fundamental logic behind the surge in gold prices. According to Reuters statistics, the increase in gold from 2024 to 2025 has approached the highest levels in nearly 30 years, surpassing 31% in 2007 and 29% in 2010. This is not a random fluctuation but the result of multiple factors resonating together.
Three main support points for the strong gold trend
Safe-haven demand driven by U.S. policy shifts
The advancement of tariff policies has directly increased market uncertainty. Looking at historical references, during the U.S.-China trade war in mid-2018, gold prices typically experienced a short-term rally of 5-10% amid policy uncertainty. The current situation has similarities, with safe-haven funds continuously flowing into the gold market.
Federal Reserve's interest rate cuts

Why is the KDJ indicator called one of the "Three Treasures of Retail Investors"? In simple terms, this indicator helps traders accurately identify market turning points and seize the best buying and selling opportunities. Compared to other technical analysis tools, KDJ has high sensitivity and strong practicality, making it an essential weapon for technical traders.
In-depth understanding of the core mechanism of the KDJ indicator
The KDJ indicator is essentially a stochastic indicator that helps investors identify trends and reversal signals by calculating price fluctuations within a specific period.
What do the three lines of the indicator represent?
This indicator consists of three curves, each with its own function:
K value (Fast line) directly reflects the relative position of the closing price on the current day within the price range of the past N days, responding to the latest market movements with the highest sensitivity.
D value (Slow line) is a smoothed version of the K value, eliminating market noise through moving average processing to provide more stable signal references.
J line (Direction-sensitive line) is used to measure

Inflation continues to rise, especially as major economies like the United States face increasing currency depreciation pressure. Relying solely on bank fixed deposits is no longer sufficient to combat the decline in purchasing power. For young people just entering the workforce, with limited salaries and rising living expenses, how to achieve asset appreciation with limited funds has become an urgent issue.
Many people have common questions:
- Can small investments really make money?
- What strategies can help funds grow quickly?
- There are so many investment channels in the market, how do I identify and choose?
This article will systematically introduce various feasible financial strategies for friends with limited funds and share how to evaluate and select suitable investment platforms. Whether you have only 1000 yuan or even 100 yuan, you can start your investment journey immediately.

There are four trading days each year, and the market experiences similar "magical moments"—these are the so-called quadruple witching days in the investment world. Many people become alert when they hear this term because these days are often accompanied by unusual and dramatic price swings. But what exactly happens behind the scenes? Why do quadruple witching days become a focal point for investors?
What is the core mechanism of quadruple witching days?
The name "quadruple witching" comes from the phenomenon of four types of derivative financial products expiring simultaneously in the United States. These four products are individual stock futures, stock options, stock index futures, and stock index options.
The pricing logic of derivatives is fundamentally different from that of spot assets. Futures and options are based on the concept of "future prices"—if the market is bullish, futures prices will be higher than the spot; conversely, if bearish. As the expiration date approaches, futures prices and the spot gradually converge, ultimately aligning at expiration. This invisible tug-of-war in prices is like being controlled by some kind of "wizard's power."

Arbitrage involves exploiting temporary price differences of the same asset across different exchanges for profit. It requires understanding market inefficiencies and navigating risks such as trading bots and blockchain delays. Caution is advised for beginners.
