Mining Status: From Geek Games to Industrial Competition
Since its inception in 2009, Bitcoin has been around for 16 years. Among many ways to acquire coins, mining has always held a unique position. However, this low-threshold path, once seen by tech enthusiasts as "earning BTC with idle computers," has now evolved into a professionalized and large-scale industry competition.
After the fourth halving in 2024, the block reward was cut from 6.25 BTC to 3.125 BTC, yet the total network hash rate remains high. Against this backdrop, the survival space for retail miners is gradually shrinking. Is it still profitable for individuals to operate mining rigs independently? This has become a concern for many.
What is the essence of Bitcoin mining?
The core logic of mining is simple: miners provide computing power to maintain the network, and the system rewards them with BTC in return.
Specifically:
- Miners refer to participants who possess mining machines and other computing equipment

First, understand the definitions of limit up and limit down
To navigate the stock market with ease, you must first grasp two important concepts.
Limit up refers to the situation where a stock's price rises to the maximum limit set by regulatory authorities within a single trading day, after which it cannot continue to climb. For example, in the Taiwan stock market, this limit is usually set at 10% above the previous trading day's closing price. If TSMC closed at 600 NT dollars yesterday, then the highest price today would be 660 NT dollars—once this level is reached, the stock price will be "frozen."
Limit down is the opposite concept, where the stock price drops to the lowest limit for the day and cannot continue to fall. Using TSMC as an example again, its lowest price today would be 540 NT dollars.
Visual Recognition: Easily identify by looking at the trading screen
Experienced investors know that during limit up and limit down periods, there are clear visual signals. The stock price chart will stay on a horizontal line, with no further fluctuations. In the Taiwan stock trading system, limit-up stocks are marked with a red background.

The white metal market in 2025 is considered a historic breakthrough. Supported by multiple positive factors such as the Federal Reserve's interest rate cut expectations, global supply shortages, and silver being officially listed on the US critical minerals list, the London spot silver price broke through the $70 per ounce mark on December 23, reaching a record high of $83.645 per ounce.
The annual increase has exceeded 140%, far surpassing gold's over 60% rise and significantly outpacing the Nasdaq Composite Index's approximately 120% increase. However, with CME recently raising margin requirements twice in a row (announced again on December 26), silver prices retreated to the $70-75 range at the turn of the year, providing an ideal entry point for investors who have not yet entered the market.
In the face of this trend, many Taiwanese investors are beginning to consider how to participate, and silver ETFs have become the retail investors' first choice due to their trading convenience.

The RMB has an obvious appreciation trend against the US dollar, mainly influenced by dollar depreciation, central bank guidance, and year-end foreign exchange settlement demand. Several institutions predict that the RMB will continue to strengthen in 2026, with good appreciation potential. The exchange rate is expected to fluctuate between 6.80 and 7.00, enhancing the attractiveness of funds.

Recently, several financial institutions such as Goldman Sachs, Bank of America, and ANZ Bank have expressed optimism about the appreciation of the Renminbi. Goldman Sachs predicts that by 2026, the USD to RMB exchange rate may fall to 6.85, while Bank of America is more optimistic, expecting it to drop to 6.80. The main reasons for the RMB's appreciation include a weak US dollar, central bank guidance, and the year-end foreign exchange settlement surge. Overall, the market remains optimistic about the RMB's prospects, with room for continued appreciation.

What is a reasonable dividend yield? First, understand this core metric
In stock investing, the dividend yield is a key indicator of dividend return. Simply put, it reflects the proportion of dividends a company pays out annually relative to its stock price.
The calculation is straightforward: Dividend Yield = Annual Dividends ÷ Stock Price. For example, if a company's stock price is $10 and it pays $1 in dividends annually, the dividend yield is 10%.
However, this metric has an important characteristic—it is composed of two factors. A high dividend yield may result from two situations: one, the company is actually increasing its dividends; two, a falling stock price leading to a relatively high yield. Therefore, when seeing a high dividend yield, it is essential to analyze which situation is driving it.
Generally, what constitutes a reasonable dividend yield depends on market conditions and the type of company. Typically, a dividend yield exceeding 4% is considered relatively high, and

At the end of the year, the RMB to USD exchange rate rebounded strongly, with offshore RMB falling to a low level, influenced by the decline in the US dollar index, central bank guidance, and seasonal foreign exchange settlement. Professional institutions generally expect the RMB to continue appreciating in 2026, while also cautioning to pay attention to external economic factors.

Quick Reference Table for US Stock Trading Hours
The US stock market is not operated by a single exchange. The New York Stock Exchange (NYSE), NASDAQ, and American Stock Exchange (AMEX) each operate independently, but their trading hours are generally synchronized.
For investors in Taiwan, the most important thing is to understand the time difference. The US observes daylight saving time and standard time, while Taiwan remains unchanged throughout the year. This results in two corresponding trading times for US stocks in Taiwan.
According to Eastern Time, the main trading sessions are:
- Pre-market trading: Monday to Friday 4:00-9:30
- Regular trading: Monday to Friday 9:30-16:00
- After-hours trading: Monday to Friday 16:00-20:00
How to calculate US stock trading hours for Taiwan?
In the US, daylight saving time begins at 2:00 AM on the second Sunday in March (clocks move forward by 1 hour), and ends on the first Sunday in November.

On December 26th, the Asian market sent an important signal—Japan's next policy move may see a shift in pace. Along with an unexpected decline in inflation data in the Tokyo area, the yen depreciated rapidly against the dollar to 156.49, significantly down from 155.80 before the data was released. Behind this sharp currency market fluctuation is the reality that Japan's inflation pressures are easing faster than expected.
Inflation data falls below expectations, with clear relief in food and energy price pressures
According to the latest data released by Japan's Ministry of Internal Affairs and Communications, the consumer price index in the Tokyo area, excluding fresh food, increased by 2.3% year-on-year in December, a significant slowdown from the previous month's 2.8%. This decline marks a new low since August, mainly due to the fading base effect from the termination of energy subsidy policies last year. Economists had generally predicted this indicator would stabilize around 2.5%, but the actual result far exceeded pessimistic expectations.
Meanwhile, the overall inflation indicator has also from

In recent years, as the global aging population trend intensifies, new drugs continue to emerge, telemedicine applications are becoming increasingly widespread, and biotech concept stocks have become a focus of attention in the capital markets. The greatest appeal of this industry lies in the fact that it is not as easily affected by economic cycles as the electronics industry—people need medical treatment regardless of economic conditions, which determines that the healthcare industry has inherent defensive qualities. Globally, the United States is undoubtedly the most mature and dynamic market in this field.
Why are biotech concept stocks worth paying attention to?
The valuation logic of pharmaceutical companies is fundamentally different from that of traditional industries.
Traditional valuation methods often fail here. Most biotech companies are in the R&D stage, lacking stable cash flow, and often report negative net profits. However, once a new drug passes clinical trials and gains FDA approval, the stock price often experiences explosive growth. Taking Taiwan's Yung Shin Pharmaceutical as an example, despite an EPS of -2.93 yuan in 2022, the company's stock price

The United States enters winter time on November 2, 2025. Taiwanese investors need to adjust their US stock trading hours to 10:30 PM to 5:00 AM. Additionally, the article lists the US stock market holidays in 2026, reminding investors to pay attention to holiday trading plans. The US stock market has three major exchanges and basic trading rules; understanding this information is crucial for Taiwanese investors.

Before Opening an Account: 5 Key Factors to Consider When Choosing a Broker
If you want to trade in the Taiwan stock market, whether it's stocks, bonds, or options, you must open an account with a securities firm. However, with so many options available, novice investors often face a dilemma. Instead of passively waiting, it's better to clarify your investment needs first.
The difference in commission fee discounts is the primary consideration. For example, with TSMC, buying 5 lots (NT$2.15 million) at a 60% discount costs NT$1,838 in commission fees, while selling 5 lots (NT$2.25 million) costs NT$1,924, plus NT$6,750 in transaction tax, bringing the total cost of a single trade to NT$10,512. The discount on commissions can be a decisive factor in the overall trading cost, but don't just look at the discount percentage—some small brokers lower fees to capture market share but compromise on service quality such as system stability and order execution speed.

The recently concluded 2025 was quite remarkable for the Australian dollar. Driven by a weakening US dollar, adjustments in tariff expectations, and domestic economic resilience, the AUD/USD pair rose a total of 7% throughout the year, demonstrating a strong appreciation trend.
Central bank policies are now diverging, leading to a change in the USD/AUD dynamics.
Entering 2026, the direction of AUD/USD will mainly be determined by three variables: central bank policy stance, economic fundamentals, and geopolitical risks.
Australia's central bank stance is inconsistent.
Currently, rising inflation pressures in Australia are widely acknowledged, but expectations for subsequent central bank actions vary. The market generally agrees that the Reserve Bank of Australia’s rate-cut cycle has concluded, but there is disagreement over whether it will initiate rate hikes in 2026.
Westpac Bank is relatively dovish, expecting the RBA to keep interest rates unchanged throughout the year. Conversely, the Commonwealth Bank of Australia anticipates a modest rate hike by the RBA. The more hawkish institutions are the National Australia Bank and Citigroup, which predict that the RBA will...

In 2025, the RMB exchange rate experienced fluctuations, oscillating between 7.1 and 7.3 at the beginning of the year. By November, due to improved China-U.S. trade relations and expectations of Federal Reserve rate cuts, it appreciated, reaching a low of 7.0765. The market expects the depreciation cycle to have ended, and the RMB will enter a medium- to long-term appreciation phase driven by export growth, foreign capital inflows, and a weakening US dollar. Investors should monitor the US dollar trend, central bank policies, and economic data to increase profit opportunities.
