Cryptocurrency markets have become a vital part of the global financial system. Since the birth of Bitcoin, the digital currency ecosystem has continuously evolved, and regulatory frameworks in various countries are gradually improving. Currently, over 300 million people worldwide participate in cryptocurrency investments, with daily trading volumes exceeding 100 billion USD. More than 18,000 companies have adopted cryptocurrencies as a payment option. So, what exactly is digital currency? How should investors make scientific choices? This article will provide an in-depth analysis from basic concepts to practical strategies.
What is Digital Cryptocurrency?
The Dual Meaning of Digital Currency
Broadly speaking, digital currency refers to currency stored and circulated electronically, including electronic payment systems and digital currencies issued by central banks of various countries (such as China's Digital Yuan). However, in the investment market, "digital currency" actually refers to decentralized cryptocurrencies.
Cryptocurrencies are based on cryptography and P2P technology, generated by computer programs, and freely circulated on the network.

The essence of inscriptions and inscription coins: breaking through Bitcoin's technical limitations
To understand the revolutionary significance of Bitcoin inscriptions, one must first grasp Bitcoin's structural limitations and the breakthroughs introduced by the Ordinals protocol.
Bitcoin has a fixed total supply of 21 million coins, each composed of 100 million satoshis, meaning the entire network has 2.1 quadrillion satoshis. The key issue is that each satoshi is interchangeable and equal in value, which leads to homogeneity and prevents Bitcoin from supporting smart contracts, issuing tokens, or NFTs like Ethereum.
In December 2022, Bitcoin core developer Cassie Rudomer introduced the Ordinals protocol, which changed everything. The protocol assigns a unique number to each satoshi, giving it an uncopyable, distinctive identity. When users write images, text, or code (limited to 4MB) onto a specific satoshi, this embedded information becomes an inscription—

For many office workers, wanting to manage finances steadily while having no time to research market analysis, fund investment is a good choice. These products are managed by professional teams, making them less risky than directly trading stocks. So, what exactly is a fund? And how should one choose and allocate them?
The essence and core advantages of funds
Definition of a fund
A fund (securities investment fund) is a collective investment tool managed by a fund manager responsible for investment operations and a fund custodian responsible for asset safekeeping. Investors pool their funds together, which are then allocated by a professional team into various assets such as stocks, bonds, and money markets, forming an investment mechanism of shared benefits and shared risks.
Why choose fund investment?
Compared to individual direct market entry, fund investment has several obvious advantages:
Asset allocation diversification
Funds invest pooled capital into different asset classes such as stocks, bonds, and commodities, providing investment breadth and depth far beyond that of individual retail investors.

Why are traders obsessed with this tool?
In the forex market, many top traders use the same method to identify support and resistance levels — it is based on the Fibonacci sequence and the golden ratio. This is not some mystical concept, but a mathematical law that has been repeatedly validated in nature and financial markets for centuries.
When you observe historical price movements, you will find that reversal points often occur at certain specific percentage levels. That’s why traders set buy or sell orders at particular levels — because these levels tend to become consensus points among market participants.
Mathematical logic of the Fibonacci sequence
The core of the Fibonacci sequence is simple: each number is the sum of the two preceding ones, extending infinitely.
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377,

Bitcoin's latest pullback from the $90,000 level has reignited a critical debate: is the "digital gold" story finally losing its grip on investors? With BTC currently trading at $92.64K—a modest -0.68% over 24 hours—the

The RMB to USD exchange rate recently broke through the 7 psychological barrier. Analysts believe that this round of appreciation is caused by multiple factors, including a weakening US dollar and supportive policies from the People's Bank of China. Investment banks generally believe that the RMB still has room to appreciate, and it is expected that by 2026, the USD to RMB will further decline, reflecting the Chinese central bank's active policy signals to promote RMB appreciation and internationalization strategy.

Gold has long been regarded as a traditional safe-haven asset favored by investors. However, many people are still confused about "how to invest in gold ETFs and which one to choose." Instead of being stuck on the high barriers and complex processes of traditional gold investment, it's better to consider gold ETFs directly—they combine gold's inflation-hedging characteristics with the flexibility of funds, offering low costs and convenient trading, suitable for both beginners and advanced investors.
What is a gold ETF? Why do so many people choose it?
Before discussing investment strategies, let's first understand what a gold ETF actually is. Simply put, a gold ETF is a type of fund product that can be bought and sold directly on an exchange. It tracks the price of gold, allowing you to indirectly hold gold assets without actually buying gold bars or spot gold at a bank.
Compared to purchasing physical gold, which often costs tens of thousands of yuan and involves storage and handling fees, the appeal of gold ETFs lies in:
Trading as conveniently as stocks—

Mid-December, the RMB against the US dollar experienced a significant turning point—USD/CNH fell below the psychological threshold to 6.9965, hitting a new low since September 2024; USD/CNY also dropped to 7.0051, the first time reaching this level since May 2023. This change indicates that market expectations for RMB appreciation are strengthening.
Three Major Drivers Behind the RMB Appreciation
The recent strength of the RMB is not accidental but the result of multiple factors resonating.
US dollar depreciation has become the main driver. Under the impact of the Federal Reserve's continued rate cuts and the global de-dollarization wave, the US dollar index has fallen more than 10% year-to-date, with recent monthly declines exceeding 2%. The weak dollar directly benefits the RMB's appreciation against the dollar.
The People's Bank of China's policy guidance is clear and strong. Since the beginning of this year, the central bank has frequently increased the RMB exchange rate in...

The USD to CNY exchange rate has fallen to a six-month low, driven by factors including a weak dollar, central bank guidance, and year-end foreign exchange settlement effects. Several institutions expect the RMB to continue appreciating through 2026, potentially reaching a target of 6.80.

On December 23rd, the Japanese Yen rebounded against the US dollar, influenced by signals from the Japanese government. The Finance Minister stated that measures will be taken against exchange rate fluctuations, and market expectations for intervention have increased. Analysts have mixed views on the Bank of Japan's future rate hike timing, and the Yen is expected to continue depreciating.

Market Focus: Policy Uncertainty Clouds Global Financial Markets
The US federal government shutdown saga has temporarily come to an end, as the House of Representatives passed a bill to end the shutdown, which will be submitted for Trump’s signature. However, full normal operations may take several days, and some agencies may not resume until next week. More troubling is that the October CPI and non-farm payroll reports may never be published, leaving the Federal Reserve in a "blind flight" during a critical decision-making period.
White House Press Secretary Leavitt admitted that the government shutdown has caused lasting damage to data collection capabilities. National Economic Council Director Hassett expects that the shutdown will drag Q4 GDP growth down to between 1.5% and 2%, with annual economic growth around 2%. This policy uncertainty has triggered a reassessment of the Federal Reserve’s future policy path.
Commodity Markets: Gold Surges, Oil Prices Under Pressure
Driven by risk-off sentiment, gold performed remarkably, rising by 1.6

"A yin and a yang is called Tao." The market has ups and downs; some see it as bullish, others as bearish. Most investors are accustomed to making money in a bull market, but smart traders understand that profits can also be made in a bear market — this is the value of short selling.
What is short selling? Why does the market need short selling?
Short selling is the opposite operation of bottom fishing. Simply put, it means that investors expect an asset to decline in value, so they sell it at a high price first (borrow the asset and sell), then buy it back after the price drops (close the position and return the borrowed asset), earning the difference.
Imagine what would happen if the market could only go up and not shorted? The result would be a straight surge when prices rise and a straight plunge when prices fall, making the market extremely unstable. With the short selling mechanism, both bulls and bears can balance each other, and market volatility will be relatively moderate.
Three major benefits of short selling:
1. Hedging risks. When the stock market is highly volatile and uncertain, and you hold a large position in a certain stock, you can use short selling to hedge.

The RMB exchange rate has recently appreciated significantly, driven by a weakening US dollar, policy support, and the year-end foreign exchange settlement effect. It is expected that the RMB will continue to appreciate in 2026, possibly falling within the 6.80-6.90 range, increasing its attractiveness to foreign investors. Investors and export companies should closely monitor exchange rate fluctuations.

The value of stable dividends is underestimated
Long-term investors tracking publicly traded companies will notice an interesting phenomenon: those that can consistently pay dividends for many years often have solid business models and healthy cash flows. In Buffett's investment portfolio, more than half of the capital is allocated to high-dividend stocks, which is not a coincidence but based on recognition of the long-term value of such companies.
In recent years, more and more investors are re-evaluating the role of high-dividend stocks. They are no longer just seen as a conservative investment synonym; instead, they have become a core holding choice for many. However, new investors entering this field are often stuck on two core questions: Will the stock price definitely drop on the ex-dividend date? Should I buy before or after the ex-dividend date?
The truth about stock price adjustments on the ex-dividend date
Theoretically, stock prices should decrease on the ex-dividend date due to cash outflow. But the reality is far more complex than textbooks suggest.
Based on historical data,

Australian gold prices continue to rise, can you still buy?
By 2025, Australian gold prices have already surpassed $4,200 per ounce, hitting a record high. Global economic uncertainties are intensifying, and young investors are rushing to allocate assets in gold. But the question is—with gold prices soaring so rapidly, is now the time to buy high or to pick up bargains?
Supporters' view: Gold is a hard currency and has always been the ultimate safe-haven asset. At worst, gold is still valuable; no matter how the global economy collapses, its value remains.
Opponents' view: Warren Buffett has explicitly said there's no need to buy gold. Gold itself does not generate cash flow, pays no dividends, and its long-term returns are not as high as you might think. Historical data shows that from 1980 to 2011, gold increased by 138%, with a compound growth rate of 2.8%. During the same period, U.S. GDP grew at a compound rate of 5.6%, and the U.S. S&P 500 performed even better.
What is the truth? Gold is moving

Commodity trading plays a crucial role in the global investment market, alongside stocks and bonds as a mainstream asset allocation option. Due to its close relationship with economic activity, price trends often accurately reflect macroeconomic changes, which is why more and more investors are paying attention to this field.
What are the targets of commodity trading?
Commodities are essentially goods that enter circulation but have not yet reached the retail stage, characterized by large supply, demand, and circulation volume. Categorized by type, they mainly include the following sectors:
Energy includes crude oil, gasoline, fuel oil, natural gas, etc., with crude oil being the most关注ed due to its massive supply and demand volume and extensive downstream applications. From plastic products to textiles, building materials, and transportation fuels, crude oil's applications cover every corner of daily life.
Industrial metals include copper, aluminum, lead, zinc, iron ore, etc., these varieties are closely linked to the industrial production cycle.
