Recently, I've been pondering a question that many people tend to overlook: How important are the concepts of Halal and Haram in Islamic faith?
Honestly, it's not just about dietary rules. I’ve noticed that many people have a basic understanding of Halal but lack a deep comprehension of Haram. In Islam, Haram represents anything that goes against God's will and is harmful to faith, the body, or society. For example, alcohol, interest-based transactions, dishonesty, theft, and oppression are all considered Haram.
Conversely, Halal refers to things that are lawful, pure, and beneficial. This inc

Recently, many people have been asking about the KD indicator, especially regarding divergence signals. To be honest, this topic has been beaten to death in the crypto community, but most people still don’t quite understand what KD divergence actually signifies.
Simply put, divergence occurs when the price and the indicator are moving in opposite directions. Normally, when the price rises, the KD indicator also moves upward. But if the price keeps making new highs while the KD decreases or even drops, that’s called divergence. It sounds simple, but the underlying meaning is quite crucial—it’s

I've been closely watching the optical communication sector lately. To be honest, the market expectations before GTC were really hyped up. If Jensen Huang can present the optical communication story in a more aggressive way this time, I think the entire sector could surge again. The logic is just too straightforward—AI clusters are growing larger, data center transmission pressures are increasing daily, copper will eventually hit a ceiling, so the next step should be optical, right?
However, Huang's final statement was a bit awkward. He definitely mentioned optical, and emphasized it strongly,

Recently, I’ve been reviewing some traders’ backtesting records and found that many have fallen into pitfalls when adjusting MACD parameters. Actually, the MACD indicator itself is fine; the problem often lies in parameter settings. Using the wrong parameters is like having a good tool but using it in the wrong direction.
Let’s start with the standard MACD parameters, the 12-26-9 combination that everyone uses most often. The fast EMA (12) captures short-term momentum, the slow EMA (26) looks at long-term trends, and the signal line EMA (9) filters out noise. This set of parameters is quite st

Recently, while watching the market, I saw someone discussing the issue of divergence again, so I decided to organize it, because this is indeed a question many people ask.
Speaking of technical analysis, you must often hear the terms "top divergence" and "bottom divergence." They are signals used to judge potential market turning points, mainly based on indicators like RSI or MACD. In simple terms, top divergence suggests a possible top, while bottom divergence indicates a potential bottom.
First, what is top divergence? Top divergence occurs when the price is still making new highs, but the

Recently, many beginners have been getting wrecked in leverage trading, mostly because they don't understand the difference between full position and isolated margin. Today, let's clarify this.
First, let's talk about full position. It's like betting your entire net worth on a single trade. All the money in your account is combined together—if you make a profit, it can double; if you lose, it can wipe out your entire account. Why do some still dare to use full position? Because it has an advantage—strong volatility tolerance. When the market dips in the short term, you can use all your funds a

I’ve been seeing an interesting piece of political-circle gossip lately: a story about a Chinese-American senior figure who’s around Trump. This guy is named Zhang Zhenxi, Steven Cheung—he’s the only Chinese-American senior figure on Trump’s team, and he’s also the most die-hard type of speechwriter.
To be honest, this fellow used to thrive around Trump, with a mouth that was really tough. Clapping back at reporters and dissing celebrities was just part of his everyday routine, and his “wolf-warrior” style remarks were already his trademark. Everyone had gotten used to his fiercely protective,

Recently, I've seen many discussions about the details of technical analysis. I want to talk about a particularly overlooked but crucial phenomenon—volume-price divergence.
Simply put, volume-price divergence occurs when the price and trading volume are not moving in the same direction. You might see a situation where the price is rising, but the trading volume is shrinking; or the price is falling, but the volume is increasing. Both scenarios are sending signals to you, but their implications are completely opposite.
First, let's discuss the situation where the price is rising but volume is d

Recently, many people around me have asked whether a cold wallet is worth buying. Instead of repeatedly explaining, I might as well write it down and discuss together.
First, the conclusion: if you hold a significant amount of crypto assets, a cold wallet is definitely a must-have. But the premise is to understand how it actually works.
Many people think wallets are places to store coins, but that's not true. Your coins are on the blockchain; the wallet just manages a pair of keys—public key (your address) and private key (your signing authority). A cold wallet is simply storing the private ke

Does anyone still believe that person claiming to be from 2058, Kokubun Rei? I recently saw her predictions flooding social groups again, saying Bitcoin will rise to 780 million yen, then "can only sell, cannot buy." But think about it carefully, is this kind of claim really credible?
Let's start with her past "success stories." Tokyo Olympics with 27 gold medals, the Nikkei index plummeting in March 2020, Shinzo Abe stepping down in September—these things did happen. But some point out that these predictions might actually be based on the economic situation and political rumors at the time, c

Recently, I’ve been a bit drawn to things related to Dogecoin mining. To be honest, this isn’t exactly anything new anymore, but looking back now, it still feels pretty interesting. DOGE has evolved from a meme coin into a more mature mining ecosystem, so I’d like to share some of my thoughts.
First of all, Dogecoin mining is definitely more approachable than Bitcoin mining. The block reward is 10,000 DOGE. At the current price of $0.09, a single reward is only a few hundred dollars, but if you have decent hardware, the accumulated returns can still be quite significant. The key is that the mi

Recently, I’ve noticed many people get confused when withdrawing tokens because of TRC20 and ERC20, so I’d like to share my understanding.
Honestly, choosing the wrong network can be really troublesome. Some people, not knowing the difference between these two protocols, end up withdrawing to a wallet that doesn’t support them—so their assets get stuck there. That’s why it’s really important to figure out what ERC20 is and what TRC20 is for safe withdrawals.
Simply put, TRC20 is a protocol based on the TRON blockchain, while ERC20 is the standard protocol on Ethereum. They look similar, but th

There's a fascinating phenomenon in the crypto world that I've noticed for many years. There's a particular coin that’s especially interesting: whenever it rises, the market crashes. It’s not a coincidence; it’s a pattern that has persisted for years. This guy has earned the nickname "Doomsday Chariot," famously known as ETC.
I consider myself an old hand with ETC. I’ve battled against the whales for years, yet I’ve never managed to make money off it. Whenever I go long, ETC immediately drops. Whenever I go short, it skyrockets. Those times really tortured me, and eventually I gave up, admitti

Recently, I’ve seen many friends around me get wiped out in contract trading, and it reminded me that this topic deserves a serious discussion. To be honest, contract trading is like a double-edged sword; used wisely, it can amplify profits, but if misused, it can lead to liquidation in minutes and heavy losses.
I’ve encountered quite a few investors who were tragically liquidated, and their experiences are quite similar. Some opened leverage too high, and even slight market reversals led to liquidation; others lacked sufficient margin and didn’t top up in time, ultimately being forced to clos

Recently, while looking at the overall landscape of the semiconductor industry chain, there is a rather obvious phenomenon worth paying attention to.
To be honest, the competitive landscape of this industry is already quite clear. The core of the global technology war lies in semiconductors, but the real chokepoints are only a handful of areas. In fields like photoresist, EDA, and lithography machines, overseas giants such as Shin-Etsu, Applied Materials, and ASML still firmly hold the upper hand. Domestic companies are trying to catch up, but the gap is indeed still there.
What’s interesting,

Recently, I’ve discovered that the metaverse gaming sector is quite interesting. Although the term "metaverse" isn’t as popular as it used to be, related games are quietly making a comeback. These games are not just about playing; they also incorporate social interactions and economic activities, allowing players to have real experiences in virtual worlds.
Since 2024, there are a few notable titles to watch. Otherside, developed by Yuga Labs, combines MMO elements with blockchain technology. Currently, only specific asset holders can access it. Pudgy World is quite interesting—it turns the pop

Recently, while trading, I was reminded of something that beginners often overlook—volume analysis. Many people ask me what exactly "vol" means. It’s actually the total amount of tokens traded within a certain period (usually 24 hours), but its usefulness is much greater than you might think.
My experience is that looking at price alone is simply not enough. You need to analyze volume in conjunction with price changes to determine whether the current trend is a genuine breakout or just a false move. When trading volume is high, it indicates strong participation from traders, and price fluctuat

Recently, many friends have been asking me about cold wallets. Actually, this is a topic worth discussing in detail. As crypto assets become more valuable, secure storage has become a top priority, and many people are considering using hardware cold wallets to protect their assets.
I’ve used a few myself. Honestly, hardware cold wallets are like an insurance safe for your crypto assets. They store private keys offline, so even the most skilled hackers can't steal them remotely. Plus, designed as USB devices, they are quite portable, which is why so many people choose them.
Regarding the mainst

Liquidity issues in the crypto space have always been a hot topic. Recently, I saw discussions about the role of market makers, so I decided to organize my thoughts.
Simply put, market makers are the players in the market who ensure that trading can proceed smoothly. They continuously quote bid and ask prices, use their own funds to place orders, allowing you to buy or sell whenever you want. Without market makers, the market can easily fall into liquidity drought, resulting in an "illiquid market" situation.
How do market makers make money? The core logic is straightforward—buy low and sell h
