I just recently figured out that many countries' currency symbols look quite similar and are easy to confuse. For example, the $ symbol is used in over 30 countries worldwide; the US dollar, Canadian dollar, Australian dollar, and Hong Kong dollar all use $. You really need to add a prefix to distinguish them.
I compiled a list of currency symbols from various countries, including the euro € , British pound £ , Japanese yen ¥ , Chinese renminbi ￥ , and some less common ones like Thai baht ฿ , Indian rupee ₹ , etc. Each symbol represents a different country's economic system, so when you see th

Recently, a friend asked me what short selling means, so I thought I’d just expand on this topic because many people still have misconceptions about shorting.
Simply put, short selling is betting that the market will fall. If you believe a stock will go up in the future, you go long; conversely, if you think an asset’s price will decline, you can sell first and buy later to profit from the price difference. That’s the core logic of short selling.
Why does the market need a short selling mechanism? Imagine if you could only buy assets to make money—markets would be very unstable—soaring when pr

Recently, I've seen many people discussing CPI data, and I realized that many investors still don't have a deep enough understanding of what CPI is. Today, let's talk about this important indicator that affects our wallets.
Simply put, CPI is the Consumer Price Index, reflecting the overall change in prices of goods and services in our daily life. It is composed of a basket of representative goods and services, and by tracking the price changes of these items, it measures the price level. The higher the CPI, the more rapidly prices are rising; if CPI is low or even negative, it indicates defla

Just saw an analysis on the RMB exchange rate and remembered a friend has been asking whether it's still possible to invest in RMB-related currency pairs. To be honest, the answer to that question isn't so simple.
A review of the past year’s trend can give some clues. From early 2025 to now, the USD to RMB has experienced quite a bit of fluctuation. In the first half of the year, it depreciated to below 7.4, hitting a new low since 2015. But in the second half, the situation reversed. As China-U.S. relations eased and the dollar index weakened, the RMB started to rebound. By November last year

I just looked at the recent months' gold price trend forecast data and found that the gold market has really experienced a rollercoaster over the past half year. From hitting a historic high above $5,600 at the beginning of the year, to a sharp correction in February, and now oscillating at high levels, many people are asking the same question: Can this rally continue?
Let's review the background. In 2025, the annual increase in gold prices exceeded 60%, marking the largest yearly gain since 1979. This strong rise mainly results from several combined factors: first, escalating trade tensions b

Recently, while studying U.S. stock trading, I found that many people actually don't understand the concept of pre-market trading in the U.S. stock market, and some people don't even know there's a trading session during this time. I think this topic is definitely worth a good discussion because its impact on investment decisions is greater than you might imagine.
Pre-market trading in the U.S. stock market, simply put, is an additional trading session before the official market open. The New York Stock Exchange and NASDAQ start as early as 4 a.m. and run until the official opening at 9:30 a.m

Recently, I’ve noticed that many people around me are paying attention to the topic of cold wallets, mainly because everyone is interacting on-chain more frequently. However, the issue of private key management really is a headache. I’ve also gone through a situation where a friend lost their seed phrase and couldn’t recover their assets, so my understanding of the need for cold wallets is quite deep.
First, let’s talk about what a cold wallet is. Simply put, a cold wallet is a cryptocurrency wallet that stores private keys on an offline device. It usually refers to hardware wallets, and it al

Recently, I’ve been paying attention to the forecast of the USD to CNY exchange rate trend and found that market expectations for the yuan’s appreciation are indeed heating up. From the end of last year to now, the performance of the yuan against the dollar has noticeably shifted, and there are many factors behind this worth noting.
Looking back, the RMB experienced a turning point from depreciation to appreciation throughout 2025. The first half was quite risky, with offshore RMB once breaking below 7.40, hitting a new high since 2015. But in the second half, the situation gradually improved,

Recently, because I needed to test SMS verification for some overseas services, I finally started using a code-receiving platform. I used to think this thing was a bit useless, but now I realize it really saves effort. Basically, it’s using a virtual number to temporarily receive verification codes, without having to actually get a new SIM card.
I’ve encountered quite a few pitfalls myself—some platforms don’t receive messages at all, others have delays of half a day. In the end, I’ve compiled a few decent ones. SMS-Activate works the most smoothly; in most cases, the verification code arrives

Recently, I recalled the Bali murder case again, which indeed is quite tragic. The incident in May 2024, where a Chinese couple was harmed in Indonesia, appears on the surface to be a bizarre murder case, but the deeper you dig, the more you can see the chaos behind the crypto world.
Here's what happened. A Chinese couple was attacked at a five-star hotel in Bali. Both were young—the man was 25, and the woman was only 22 and still in college. The police autopsy report showed that the male victim had multiple cuts and even signs of electrocution; this method clearly wasn't an ordinary crime. Th

Recently, I was studying the legendary traders of the Japanese stock market and found a very interesting comparison.
One is the "God of Trading" Takashi Kotsukawa, and the other is known as the "Strongest Retail Investor" CIS. These two are not only friends but also have remarkably similar experiences—they both started trading in college, gradually growing their small funds into hundreds of millions of yen. Even more legendary is that they both made their names during the 2005 J-COM order misplacement incident, with CIS earning 600 million yen that day, and Takashi Kotsukawa even more aggressi

Recently, I saw many beginners in the community asking how to calculate profit and loss, and I realized this is indeed a fundamental issue that’s easy to overlook. Actually, understanding what PnL means is really crucial for traders, especially when you hold multiple cryptocurrencies and buy or sell at different times.
Let's start with the most straightforward concept. Profit and loss refer to the change in the value of your held crypto assets compared to the purchase price, reflecting whether you've made a profit or a loss over a specific period. But there are several details here that can be

Recently, many people have been asking how to make money with cryptocurrencies. In fact, quite a few people still think you can only profit by trading. However, making money with crypto is far more than that. Today, I’ll lay out 10 methods I’ve learned about—some are completely free, while others require you to invest. It’s up to you to choose.
First, let’s talk about the free options. Claiming an air drop should be the easiest way to get started. Projects simply give you tokens for free, in two forms: active and passive. Active options require you to complete certain tasks—such as registering

Recently, I’ve been looking at U.S. stocks and discovered an interesting investment direction—defense stocks. Over the past two years, geopolitical tensions have been getting increasingly tense; the Russia-Ukraine war and Middle Eastern conflicts have been happening frequently. Countries have begun to realize a problem: future wars will no longer rely on mass-troop tactics, but will be fought by competing on technology, drones, and information warfare. This has directly led to global military spending rising year after year, and many countries are increasing their defense spending.
When it com

Recently, I noticed an interesting turning point in the trend of the RMB exchange rate. After experiencing three consecutive years of depreciation from 2022 to 2024, the RMB seems to have found a new rhythm. In November last year, the USD to RMB exchange rate rose below 7.08, even touching 7.0765, hitting a nearly one-year high, which many people are discussing.
Looking back at the performance throughout 2025, the first half was indeed quite tough, with global tariff policy uncertainties, a strengthening US dollar index, and offshore RMB once breaking above 7.40. But in the second half, as US-

Recently, many friends around me have been asking about cold wallets, and I realized that many people are still a bit confused about this. Today, I want to share my understanding in hopes of helping those who want to get started.
Honestly, when I first came into contact with crypto assets, I was also quite confused. Using a hot wallet is convenient, but I always felt uneasy about storing private keys on my phone or computer, especially after seeing so many theft cases. Later, I gradually understood that a cold wallet is basically storing private keys on an offline device; physical isolation ca

Recently, a friend asked me how many types of cryptocurrencies there are now and how to choose. Actually, that's a good question because many people jump into the crypto world without understanding what they are buying, just attracted by market trends. I think it's necessary to clarify the basic concepts first.
When it comes to cryptocurrencies, Bitcoin is unavoidable. This thing is essentially a new form of money, but not issued by any government. Many people initially question, isn't money supposed to be issued by central banks to be legitimate? Isn't Bitcoin challenging authority? Actually,

Recently, while doing foreign exchange trading, I realized that the currency symbols used by so many countries around the world vary so much. The US dollar symbol is just $, but did you know that over 30 countries worldwide also use $ as their currency symbol? This can easily cause confusion. For example, the US dollar is US$, the Canadian dollar is C$, Hong Kong dollar is HK$, Australian dollar is A$, which look similar but represent completely different currencies.
Another interesting point is the ¥ symbol, which represents the Chinese Renminbi in China, but in Japan, it is the Yen. So, for

Recently, I’ve seen more and more people in the community discussing the topic of airdrops, and upon reflection, it’s indeed worth paying attention to. Compared to directly buying coins, earning rewards through airdrops—an approach that requires little to no investment—has now become an important way for many to participate in the crypto space.
The concept of airdrops is actually very simple. In English, it’s called Airdrop, which basically means that project teams distribute tokens directly to users or have users claim them to promote and build their ecosystem. The earliest can be traced back
