Recently, I’ve noticed many people are still debating which network to choose when transferring USDT—TRC20 or ERC20. In fact, this question is more important than you might think because choosing the wrong one not only wastes transaction fees but also significantly affects the speed of arrival.
First, here’s the conclusion—if you want to save money and transfer quickly, TRC20 is definitely the top choice; but if the platform you’re using only supports ERC20, then there’s nothing you can do. Today, I’ll clarify the differences between these two networks for you.
**What are the advantages of TRC

I just realized a problem: many people have been trading stocks for years, but they don't have a deep understanding of the turnover rate of stocks. To be honest, if you haven't understood this concept thoroughly, watching more candlestick charts is pretty much useless.
Let's start with the basics: the turnover rate is the frequency of buying and selling stocks, reflecting how active a stock is. The simple calculation is trading volume divided by the circulating shares, multiplied by 100%. For example, if a stock trades 10 million shares in a month and the circulating shares are 20 million, the

Tomorrow is again the anniversary of 519. As an experienced investor who went through that storm, I still occasionally recall the scenes from back then. The 519 crypto incident is indeed a textbook market lesson; the feeling of huge swings, I remember clearly to this day.
Looking back, the trigger was actually very simple—Elon Musk’s tweet. In early 2021, when he bought $1.5 billion worth of Bitcoin for Tesla, the whole market was cheering, but in mid-May he suddenly changed his tone, first announcing to stop accepting Bitcoin payments, citing environmental concerns, then hinting at possibly s

Recently, a friend asked me about what a cold wallet is, and I realized that many people still have a bit of confusion about this concept. Today, let's talk about this topic.
In fact, a cold wallet is essentially an offline storage device, specifically used to hold your private keys. Its biggest feature is that it is not connected to the internet at all, so hackers and malicious software basically can't access it. Your crypto assets are like being locked in a safe; unless you actively take them out, no one can move them.
What does a cold wallet actually look like? Usually, it appears like a US

Recently, I noticed a pretty interesting phenomenon: forecasts from the five major banks about the US QE timeline are rolling out one after another, and these forecasts have sparked a lot of discussion in the crypto market.
US banks expect the end of balance sheet reduction to be announced in October this year, with small-scale bond purchases starting in December. Citibank believes the announcement will be made in December, with official implementation in January next year, buying about $20 billion in government bonds each month. Barclays’ view is that it will start in February 2026, with $15

Recently, I’ve been chatting with some traders and found that many people don’t have a deep understanding of the concept of slippage. Especially for frequent traders, if you don’t understand how slippage occurs, your costs can unknowingly increase significantly.
Simply put, slippage is the difference between the expected price when you place an order and the final transaction price. Particularly when using market orders, due to market volatility or insufficient liquidity, you might execute at a price higher or lower than expected. I’ve seen cases where someone places a large order, and the cos

Recently, I’ve been studying the divergence rate indicator and found that many people actually don’t quite understand its true purpose, especially those trying to use it to find buy and sell points. Simply put, the divergence rate is a tool to measure how far the price is from the moving average, with the core logic that prices will eventually revert to the average cost.
Let me start with a basic concept: calculating the divergence rate is quite simple. It’s (today’s closing price minus the N-day moving average) divided by the N-day moving average, then multiplied by 100%. A positive result in

Recently, many people have asked me what VC is, so I’ll just explain it systematically. Simply put, a VC project is a venture capital project. In other words, someone is optimistic about a particular startup or technological direction, pours money into it in exchange for equity or returns—betting that these companies can grow quickly. These types of projects usually target areas like technological innovation and emerging startups; they have great potential, but the risks aren’t small either.
Now the question is: I’ve noticed that the way many VC projects play today has kind of changed for the

I have been thinking about the evolution of the internet recently, from static Web 1.0 to interactive social Web 2.0, and now we are entering a completely different era. Web3 has truly arrived, and the changes are much deeper than we imagined.
Honestly, the concept of Web3 seems a bit complicated, but at its core, it’s very simple—it's about reclaiming control of the internet from big corporations and giving it back to users. Data is no longer stored on a central server but distributed across countless nodes worldwide. It sounds like science fiction, but blockchain, smart contracts, and distri

Recently, gold has been surging again, approaching the historic high of 5200. But I’ve noticed many people around me don’t really understand how to play this game; they see others buying and just follow suit blindly, which is actually quite risky. Today, I want to share some of my thoughts on gold investment.
When it comes to gold, everyone’s first reaction is preservation of value. That’s correct; during economic fluctuations and inflation, it indeed acts as a safe haven. But there’s a misconception—many people buy gold jewelry, keep it at home, which can’t generate income and also risks loss

Are friends new to the crypto world getting overwhelmed by all kinds of jargon? I’ve put together a basic glossary of crypto terms to cover most of the concepts you need to know, hoping to help you get started quickly.
First are a few fundamental concepts. Fiat currency is government-issued money, such as RMB or USD, backed by national credit. Token is usually translated as “digital token,” which is proof of rights on the blockchain, allowing the exchange of value through accounting of physical or digital assets. This is the core of what crypto is—a value circulation system based on digital re

Recently, I’ve seen quite a few people fall for cryptocurrency scams, and I think it’s still necessary to talk about it. Depositing $500k in a bank takes 5 minutes, but clicking on a stolen U-link is gone in less than a second. The gap is really frustrating.
I’ve noticed that scammers in China have now upgraded from traditional telecom fraud to the cryptocurrency space. The most heartbreaking thing is that when victims report the case, many police officers don’t even know what USDT is, and some directly say that virtual currencies are not protected by law, so they don’t file a case. As a resul

I've been thinking about a question recently: Are there really that many legitimate online money-making opportunities? The answer is yes, and there are even more than you think.
According to data from the Pew Research Center, about one in six Americans earn extra income through online platforms. This is nothing new, but many people still don't know where to start. I believe the key is to find a method that suits you, rather than blindly following those schemes claiming to make you "get rich overnight."
Let's talk about freelancing first. If you have a certain skill, platforms like Upwork are t

When I reviewed my trading system recently, I found that many people have a misconception about MACD parameter settings—they think that finding the “best parameters” can solve all problems, but that simply isn’t the case.
I’ve been using MACD myself for a few years now. At the beginning, I used the default 12-26-9. Honestly, this set of parameters is indeed quite versatile: it reacts to short-term momentum with the fast EMA (12), captures long-term trends with the slow EMA (26), and uses the signal line EMA (9) to filter out noise. The reason major trading platforms set this combination as the

Recently, I’ve noticed that newcomers in Discord often get confused by these crypto terms, so I want to organize them to help everyone avoid pitfalls.
Let’s start with the basics. You’ve probably heard the word HODL — actually, it originally was a typo of someone typing “hold,” which ended up becoming a community mantra. It means buying and holding, not panicking and selling even when prices drop. Some veteran players I know do exactly that — when BTC drops from 60k to 30k, they keep buying, and now they’re making a huge profit.
Next is FUD — Fear, Uncertainty, and Doubt. The word FUD actually

I just saw a remark from European Commission President von der Leyen, and it’s quite thought-provoking. She mentioned that Russia proposed a ceasefire during Orthodox Easter; does that sound like a sincere gesture? But the reality is far more complicated.
According to von der Leyen, this ceasefire proposal is just a smokescreen. Russia publicly talks about a ceasefire, but secretly prepares to launch even more brutal attacks on Ukraine. This kind of tactic of negotiating first and then turning hostile has been openly exposed by von der Leyen.
This European leader’s perspective is quite straigh

Recently, I’ve seen quite a few people fall victim in trading, especially when the price suddenly surges and breaks through key levels—that’s what we often call a bull trap.
Let me start with a real scenario. After the price has been declining for a long time, suddenly there’s a strong upward move, directly breaking through the previous resistance level. Beginners see this signal and start buying frantically, thinking a rebound is finally happening. But the problem is, after just a few candlesticks, the price turns downward again. Those who bought at the high get trapped.
Why does this happen?

At first, I was skeptical when I heard people say they could make money playing games, until I actually tried a few P2E games and realized it's no joke. Playing casually for a week can earn you $20 to $30, which isn't a lot of money, but it's entertainment with earnings—some players even make hundreds or thousands of dollars a month from these earning games.
How do these games work? Simply put, they are built on blockchain, so what you earn in the game isn't locked inside the game but can be withdrawn and exchanged for real money. Completing tasks, winning battles, mining, staking resources, t

I just came across a geopolitical issue worth deep reflection—recently, the US-Iran conflict has escalated, and many people only see the surface-level military confrontation, ignoring what the true root cause of the US-Iran war really is.
Honestly, the roots of this conflict are much deeper than we think. We need to go back nearly a century in history. In 1953, the CIA orchestrated a coup to overthrow Iran’s Prime Minister Mosaddegh, with a very direct goal—controlling oil resources. Afterwards, they installed the Shah’s regime, and Iran became an important US ally in the Middle East. But in 1
