Recently, I’ve seen many newcomers in the community confused by the various English abbreviations related to blockchain, and I totally understand. Terms like PoW, PoS, and DPoS sound complicated, but the underlying logic isn’t hard to grasp.
First, let’s talk about PoW, Proof of Work, which is the mechanism used by Bitcoin. Simply put, whoever’s computer can solve the math problems faster gets the right to record transactions and earns rewards. Imagine everyone working together to solve a math puzzle—whoever solves it first wins the right to record the block and receives digital currency as a

Recently, many beginners have been asking me about blockchain wallets. So today, I’ll organize my understanding over the years and explain what a decentralized wallet really is.
To understand wallets, you first need to know how blockchain works. Main chains like Ethereum (ETH) rely on countless nodes verifying transactions together to operate normally. The people running these nodes are what we call miners. Mining rewards go directly into the node’s wallet. But here’s a problem—early on, trying to use these rewards for transfers or other operations was extremely complicated, requiring you to r

Recently, a beginner asked me about the meaning of long and short positions, so I thought I’d organize and share it with everyone.
Let’s start with long positions. It’s pretty straightforward—you’re bullish. You buy an asset, expecting its price to go up, and then sell high and buy low to profit from the difference. For example, I bought 1 Bitcoin at $20,000, thinking it would eventually rise to $25,000. Sure enough, it did, and I sold it for a $5,000 profit (excluding fees). The risk with this kind of position is relatively manageable—at worst, you lose your initial investment.
Short position

Recently, when backtesting trading strategies, I found that many people have quite a few misconceptions about MACD parameter settings. Instead of trying to find the perfect parameter combination, it's more about finding the one that best suits your trading style.
Let me share an interesting observation. I compared the performance differences of MACD (12-26-9) and MACD (5-35-5) on Bitcoin daily charts, using data from the first half of last year. The results are quite clear: the more sensitive one (5-35-5) generates signals nearly twice as often as (12-26-9), but the proportion of signals that

I saw that Zeta company did an institutional financing round the year before last, issuing a convertible promissory note to raise $6 million, with zero interest. Later, they also completed a 1:100 stock merger that took effect on Nasdaq. To be honest, this kind of operation is quite common in institutional financing, where the issuer uses conversion rights to dilute equity. However, their main focus is on Bitcoin-related financial platforms, covering asset management, liquidity aggregation, and mining. It seems they want to position themselves within the BTC ecosystem. I feel that financing fo

Recently, I’ve been analyzing some on-chain data metrics and found that the MVRV tool is definitely worth in-depth study. Many people lose money trading cryptocurrencies simply because they lack an understanding of market cycles, and MVRV happens to be able to tell you where the market is from a long-term cycle perspective.
In simple terms, MVRV is the ratio of Market Value (MV) to Realized Value (RV). Realized Value is the sum of the last movement values of all Bitcoin on the chain, indirectly reflecting the cost basis of long-term holders. Compared to just the circulating market cap, this in

I recently came across a set of data that I found quite interesting. We often say that the United States is the wealthiest country in the world, but when looking at per capita GDP, the situation is completely different. Although the US has the largest economy overall, it ranks only around 10th in terms of national income, with a per capita GDP of about $89.7k.
In the true global wealth rankings, smaller countries tend to be the winners. Luxembourg leads with a per capita GDP of $154.9k, followed closely by Singapore at $153.6k. Macau, Ireland, and Qatar also far surpass the US. It seems that t

I recently discovered something quite interesting — the renminbi is called the renminbi domestically, but why does it become CNY abroad? There are actually many stories behind China's financial internationalization.
First, let's talk about why there is this distinction. RMB and CNY are both abbreviations for the renminbi, but they represent completely different concepts. RMB is the pinyin abbreviation for "Renminbi," which is the local term. But CNY is the internationally recognized standard code — it follows the international currency code conventions, combining the initials of China and Yuan

Recently, I’ve seen a bunch of crypto terms on Discord and Twitter, and beginners just don’t understand what they’re talking about. What do words like HODL, WAGMI, FUD actually mean? Actually, these aren’t some complicated concepts; they’re just slang created by the crypto community. Once you understand them, you can chat with everyone without feeling awkward.
Let’s start with HODL, which is the most interesting. In 2013, someone made a typo on a forum—meant to type “hold” but accidentally typed “HODL.” It then became a symbol of faith in the crypto world. The meaning is simple—buy in and don’

Recently, someone asked about coin-margined contracts, so I’ll share my understanding.
In simple terms, coin-margined contracts use coins as collateral, and profits and losses are also calculated in coins. This is different from U-margin contracts, which use U as collateral and denominate everything in U. At first glance, there’s not much difference, but in reality, the differences are significant.
I’ve noticed that many people overlook one point: coin-margined contracts inherently have a 1x long attribute. Think about it—if you first buy coins with U for spot trading, then open a coin-margine

The Malaysian police recently launched a series of raids in Perak State, seizing 41 machines suspected of being used for illegal mining within three days, which is quite a significant scale. It is said that the first operation uncovered 24 units, followed by 9 and 8 units respectively. Such large-scale mining equipment crackdowns seem to be uncommon locally. Authorities stated that the violations involve criminal law and electricity supply regulations. No arrests have been made yet, and the case is still under investigation. It seems that countries are indeed increasing their efforts to crack

I recently observed an interesting phenomenon: many people are starting to seriously consider wallet security issues. Especially after some major exchange risk incidents, everyone is asking the same question: where is the safest place to store assets?
To be honest, many people still have a vague understanding of what a crypto wallet actually is. A wallet isn’t really where your coins are stored; it’s a digital tool that allows you to manage, send, and receive virtual assets. In simple terms, it’s like a passport in the blockchain world—without it, you can’t perform various operations.
The core

Lately I've been pondering a question: what are the underlying patterns of the crypto bull market? After observing so many cycles of ups and downs, it seems there are indeed some clues to follow.
Looking back at historical data, a full bull market cycle roughly lasts about 4 years. 2013, 2017, 2021—if this rhythm continues, the next bull run should start around 2025. But now it's already 2026, and looking back, this cycle has unfolded as expected.
The logic behind a bull market isn't actually complicated. First, institutions quietly accumulate positions, then the halving event acts as a cataly

Recently, I’ve been thinking about a very interesting phenomenon. Over the past decade of development in the crypto market, there has been a widely circulated joke in the community—"Playing coins belongs to someone." What this phrase reflects is actually an extreme concentration of market power during a certain period.
A few years ago, a major exchange indeed controlled most of the market traffic. At that time, the industry landscape was very simple—most funds and users flowed into the same platform. But looking back now, this phenomenon has gradually been changing.
One detail worth noting is

Finally understanding the concept of turnover rate. To be honest, many people who have been trading stocks for years still feel confused.
What exactly is the turnover rate? Simply put, it’s the frequency of buying and selling stocks, reflecting how active the stock is. To understand what stock turnover means, you need to know: what does a high turnover rate represent? What does a low turnover rate indicate? This is the key to truly identifying the actions of the main players.
Let me give you an example. A stock with a monthly trading volume of 20 million shares and a circulating share capital

I've been thinking a lot about prediction markets lately, and the more I think about it, the more something feels off.
Everyone talks about how powerful prediction markets are—beating polls, outperforming experts, crushing traditional forecasting tools in the 2024 U.S. election. Suddenly, platforms like Polymarket are hailed as “truth discovery machines.” Sounds great, right? Markets aggregate dispersed information, people put real money behind their beliefs, and ultimately, the prices converge to the truth.
But here’s the problem. Last year, a trade made me realize what “getting the early wat

I just saw the list of virtual currency platform operators published by Taiwan’s Financial Supervisory Commission, and this round of VASP registration is really getting serious. In the September review, 9 operators successfully passed (including better-known ones like MaiCoin, BitoPro, and XREX), but at the same time, 18 were directly removed, meaning they can no longer provide virtual asset services.
It seems the FSC is taking it seriously to crack down on this market. Under the Anti-Money Laundering Act, operators must complete anti-money-laundering registration in order to operate legally.

I recently came across a very interesting mechanical keyboard, the DIGIART MASS 80. It has a 3.4-inch touch screen embedded in the top right corner, which seems designed for people who are tight on desk space. The screen resolution is 480 × 480, and you can slide or tap to adjust volume, screen brightness, or use it as a shortcut key to skip songs or set virtual shortcuts. This feature is quite practical, allowing you to control many functions without leaving the keyboard.
The screen also displays real-time CPU usage and system time. It has a built-in Pomodoro timer to help you allocate work a

I just came across a rather interesting policy contradiction—Trump’s nominated new Federal Reserve Chair, Jerome Powell, advocates for both rate cuts and balance sheet reduction at the same time. At first glance, this seems self-contradictory, but the underlying logic is actually worth paying attention to.
Powell is 55 years old and was a candidate for Fed Chair as early as 2017. His background is impressive—serving on the Federal Reserve Board from 2006 to 2011, experiencing every step of the 2008 financial crisis. Back then, he was famously hawkish, even opposing QE2, firmly believing that e

Sony recently announced the WF-1000XM6 true wireless noise-canceling earbuds, and this time the evolution seems quite comprehensive. I noticed that the new earbuds have undergone significant design changes, shifting from the previous triangular shape to an oval form. At first glance, the size appears larger, but Sony has actually reduced the contact area with the ear by 11%, making it fit more snugly and comfortably for long-term wear. The charging case has also changed from an asymmetrical design to a minimalist oval cylinder, which also supports wireless charging.
More notably, the noise-can
