Recently, more and more people around me are paying attention to cold wallets. To be honest, this is indeed a matter worth paying attention to.
First, let's talk about why. When interacting on the blockchain, the biggest concern for many is poor management of private keys and seed phrases. If lost or stolen accidentally, assets are gone. So, cold wallets have become a necessity for many. But the problem is, there are so many types of cold wallets on the market, how to choose and how to use them, many people are at a loss.
Simply put, a cold wallet essentially means storing your private key on

Recently, a friend asked me how to use the divergence rate to judge stock buy and sell points. I found that many people are still a bit confused about this indicator. So today, I’ll share my understanding.
To put it simply, the divergence rate is an indicator that measures how far the stock price has moved away from its moving average. In English, it’s called BIAS. A simple way to understand it is: how big is the gap between the current stock price and the moving average. This indicator is especially suitable for finding short-term overbought and oversold opportunities—such as when the stock p

I just realized during international transactions that I really don’t understand how to use various currency symbols. The dollar sign $ , euro € , and British pound £ are okay, but symbols like Japanese yen ¥ and Chinese yuan ¥ look exactly the same, which can be really confusing.
Later, I understood that currency symbols are actually just shorthand tools; writing $100 is much faster than writing "100 US dollars." The key is to quickly identify the value fluctuations of different currencies during forex trading or international payments. For example, seeing a currency pair like EUR/USD tells y

Recently, a friend asked me how to calculate the investment return rate, and I realized that many people are still a bit unclear about the concept of ROI. So I organized my understanding and shared it with everyone.
The investment return rate is called Return on Investment in English, abbreviated as ROI. In plain terms, it measures whether your investment has actually made money. Expressed as a percentage, it is widely used for personal investment decisions, and it can also be used to compare the efficiency of different investments.
The most basic ROI calculation formula is: **(Net Profit / To

Recently, many beginners have been asking about limit-up and limit-down in stocks, so I’ll organize my understanding here. Actually, limit-up and limit-down are common phenomena in the stock market; simply put, they occur when the stock price reaches the maximum allowed increase or decrease.
Taking the Taiwan stock market as an example, the limit-up restriction is that the stock price cannot exceed 10% of the previous day's closing price. If a stock closed at 600 yuan yesterday, today it can only rise to a maximum of 660 yuan. Conversely, limit-down means the price can only fall by 10%, which

Recently, many people have been asking how to play liquidity mining, so I’ve organized my understanding and shared it with everyone.
To be honest, although the concept of liquidity mining sounds impressive, the principle is actually very simple—it's about putting your tokens into a liquidity pool, and when the platform or other traders use this pool for trading, you can earn a share of the trading fees and platform rewards. In other words, liquidity mining is a way to make money by providing liquidity.
Here, I want to correct a common misconception. Many people confuse liquidity mining with tr

Recently, I’ve been looking at forecasts for the RMB exchange rate trend and found that some things are still worth paying attention to. Looking back over the entire last year, the RMB’s performance against the US dollar really did show a turning point. Based on data from 2025, the USD to RMB rate has been swinging back and forth between 7.1 and 7.3, appreciating by 2.4% over the whole year. By the end of November, driven by easing US-China trade tensions and expectations of Federal Reserve rate cuts, the USD to RMB rate even fell to below 7.08, with a low of 7.0765—its strongest level in near

Recently, many beginners have been asking what a limit-up is, so I decided to clarify this part.
Actually, limit-up and limit-down are the "ceiling" and "floor" in the stock market. For example, in the Taiwan stock market, the daily price change limit cannot exceed 10% of the previous day's closing price. In other words, if TSMC closed at 600 yuan yesterday, today the highest it can go is 660, and the lowest is 540. Once the stock price hits this limit, trading is frozen, which is the state of limit-up or limit-down.
How to tell if a stock has hit the limit-up? Very simple, just look at the ca

Many people ask how much a share costs when trading stocks.
Actually, this question seems simple, but it involves differences in trading rules across various markets.
Today, let's clarify this basic knowledge.
First, understand what a share is.
A share is the smallest unit of stock trading.
To raise funds, a company divides its equity into several parts for trading; each part is one share.
For example, if a company has a capital of 10 million yuan and divides it into 1 million shares, then each share has a face value of 10 yuan.
However, it’s important to note that the face value o

I want to talk with everyone about leverage trading, especially the logic behind liquidation, because many people haven't truly understood what happens behind the scenes.
Let's start from the basics. Suppose Bitcoin is $50k each, and you buy one with $50k in cash—that's a regular trade, very simple. But what if you use leverage? Same purchase of one Bitcoin, but you only need to put up $5,000, and the remaining $45,000 is covered by me—that's tenfold leverage. Sounds tempting, right?
The problem is, that $45,000 isn't given to you for free; it's borrowed. Suppose the price of Bitcoin rises to

Recently, I noticed an interesting phenomenon: the ETF applications for LTC, SOL, and XRP are all moving forward. Behind this, it actually reflects a bigger trend—cryptocurrencies are accelerating their integration into the traditional financial system.
Many people ask what coin an ETF is. But that question is backwards. An ETF is not a coin; it’s a trading instrument. Simply put, an ETF is an exchange-traded fund, which you can buy and sell on a securities exchange just like stocks. The biggest difference is that an ETF tracks a particular asset or a basket of assets—such as gold and indexes—

Recently, I've noticed many beginners are interested in contracts for difference (CFDs), so I’ll organize my understanding here.
CFDs are essentially a form of margin trading; in simple terms, you’re betting whether the price of an asset will go up or down with the trading platform. For example, if you’re bullish on a currency pair, you can buy a contract to go long; if you think it will fall, you sell to go short. Throughout the process, you don’t need to own the actual asset—just focus on price movements to profit from the difference.
Let me give a simple example to explain how CFDs work. Su

Recently, while chatting, I found that many people are still a bit unfamiliar with futures, and some even have misconceptions. In fact, futures aren’t that mysterious. Today, I’d like to discuss this topic from an investor’s perspective.
The origin of futures is actually quite interesting. Going back to the agricultural era, farmers’ biggest fear was natural disasters affecting their harvests. During bumper harvests, prices would crash; during poor harvests, prices would skyrocket. These uncontrollable fluctuations were a nightmare for everyone. Westerners came up with a solution—by signing co

Recently, people have been asking me whether the US dollar exchange rate will keep falling. This question is absolutely on point. Judging from the trend over the past year, the US Dollar Index has faced noticeable downward pressure, and this trend may continue in 2026.
First, let me walk everyone through the dollar’s historical cycles. Since the collapse of the Bretton Woods system in 1971, the US Dollar Index has gone through eight distinct phases. In the 1970s, the Nixon administration abandoned the gold standard, sending the dollar into an oversupply period; later, it was hit by the oil cri

Friends who have been paying attention to gold market trends should have noticed that the recent surge in gold prices has been quite strong.
The gold price has increased by 64.72% throughout 2025, setting the strongest annual performance since 1979, reaching a high of $5,600 per ounce earlier this year.
Although there has been some pullback now, overall it remains at a relatively high level.
Regarding the price of Malaysian 916 gold, it has also fluctuated quite a bit along with international gold price movements recently.
Previously, local 999 pure gold prices approached 750 to 800 ri

Recently, I've been looking into high-dividend stocks in the U.S. stock market and found that this area is really worth paying attention to. Last year, the U.S. stock market rose quite a bit, but the dividend yields actually decreased, with the S&P 500 now around 1.2%, near a 20-year low. However, this presents an opportunity for us because there are still some undervalued dividend kings in the market, with annualized returns exceeding 5%.
I analyzed some data and compiled a few representative high-yield stocks. Enbridge, an energy infrastructure company, is particularly interesting; it has in

I’ve been keeping an eye on today’s gold price trend. The gold market has indeed been quite hot lately. I checked the data: not long ago, spot gold was moving within a tight range at a high level of more than $5,000 USD, and the quotes from Malaysia’s local gold shops also rose accordingly—making the retail price of 999 fine gold approach around 750 Malaysian Ringgit per gram.
What’s interesting is that the quotes from different gold shops vary quite a bit. My friend went to several gold shops a couple of days ago to ask about today’s gold price and found that some places have already switched

Recently, I’ve noticed that many people around me want to enter the U.S. stock market but don’t know where to start. I’ll summarize some of my experiences in hopes of helping beginners understand how to buy U.S. stocks.
First, it’s important to understand that investing in U.S. stocks isn’t as complicated as it seems. The key is to clarify your account type. Most retail investors are suitable for opening a “cash account,” which operates more conservatively, does not allow overdrafts or short selling, but the risks are more controllable. If you have some experience and capital, you might consid
