Recently, a friend asked me about contract trading, and I found that many people actually can't distinguish the difference between USDT-margined and coin-margined contracts. I previously wrote an introductory article, and today I want to give everyone a more systematic overview, especially for those who want to deepen their understanding.
First, let's state the conclusion: Cryptocurrency contract trading is mainly divided into two major categories: USDT-margined contracts and coin-margined contracts. Exchanges typically offer three types: perpetual USDT-margined, perpetual coin-margined, and d

Recently, when analyzing some technical charts, I found that many people actually lack a deep understanding of the descending wedge pattern. I want to share some practical observations and trading ideas.
Let's start with a recent example. Gold formed a clear descending wedge from early to mid-2024, with prices continuously making new lows but the decline gradually narrowing, making the entire pattern look like it's tightening. You will notice that the trading volume gradually diminishes during this process, which is a very key signal—the market is waiting for a breakout. When the price finally

Recently, I've seen many beginners ask about perpetual contracts, so I thought I might as well systematically discuss it and break down this seemingly complex topic.
Actually, perpetual contracts are simply a "trading scenario that never closes." Unlike traditional futures that settle at expiration, perpetual contracts are like an endless game—you can enter and exit at any time. The coolest part is—you don't need to actually buy coins; just put up a small margin to control a position much larger than that amount. For example, with a $100 margin and 10x leverage, you can control $1,000 worth of

Someone recently asked me, how to make big money in the stock market?
Actually, it's quite simple—it's about recognizing those high-quality leading stocks that are undervalued, then having the patience to absorb shares and hold.
It sounds easy, but most people find it difficult to do in practice.
My experience tells me that if you can hold such stocks for more than 3 years, the probability of earning 1 to 3 times profit is about 60% to 80%.
If you can hold for over 5 years, this probability can reach 80% to 90%.
Why? Because the hardest part in the stock market isn't picking stocks,

Recently, there’s been renewed discussion in the community about that Japanese “future person” Kōbun Rei, who claims to come from 2058. To be honest, I was half-believing it at first. But judging by her past prediction records—such as the number of gold medals at the Tokyo Olympics, the timing of the Nikkei index’s plunge, and when Shinzo Abe stepped down—everything really does line up. No wonder so many people believe her.
What’s most interesting is her crypto investment story. She said that at the end of 2019, she bought more than 1,400 Ether in one go through her father’s account, and then

I recently saw a set of data that was quite shocking. The silver inventory at the Shanghai Futures Exchange has hit a nearly ten-year low, now only 318.5 tons, a level not seen since October 2015. Even more astonishing is that in just a few months this year, silver stocks have evaporated by 54%, with more than half of the reserves taken out in a short period.
What does this imply? As the world's largest consumer of precious metals, China’s demand for physical silver is truly insatiable. Once the exchange’s silver inventory drops to such a dangerous level, supply-side issues begin to emerge. Th

Recently, I’ve noticed that many traders are discussing moving average indicators. In addition to the classic MA (Moving Average), there’s also a widely used EMA (Exponential Moving Average) configuration approach that’s worth getting a deeper understanding of.
EMA and MA look similar, but the way they’re used is very different. MA is a simple moving average: it adds up the prices over a period of time and divides by the number of periods, reflecting an average level. EMA is different. It’s a weighted moving average, giving higher weight to more recent prices and lower weight to earlier prices

Recently, the term "hodler" has been frequently seen in the community, which is actually a concept created within the Bitcoin circle. Simply put, a hodler is someone who, regardless of how the price of the coin rises, stubbornly holds onto their BTC without letting go.
Bitcoin's volatility is indeed frighteningly high. Supply and demand determine the price, so it's common to see people cash out at the high points, making millions and then leaving. But hodlers are different; they seem to have a kind of obsession, ignoring the ups and downs of the price, just holding onto their positions.
The lo

I happened to see a beginner asking about the basic concepts of contract trading, so I’ll share my understanding. Honestly, the terms open position, close position, and holding position can indeed be confusing in the crypto world, but they’re not hard to understand.
Opening a position means establishing a new trading stance in the market. For example, if you’re bullish on a certain coin, you buy it, which is called opening a long position. Conversely, if you’re bearish on a coin, you sell it, which is called opening a short position. When opening a position, you need to pay margin to cover pot

I’ve noticed that when many beginners enter the crypto world, they get thrown off by all kinds of jargon—HODL, WAGMI, FUD. What do these terms actually mean? Let’s break them down today.
First, let’s talk about HODL. The most interesting thing about this word is that it’s actually a typo. Someone originally meant to type “hold,” but accidentally typed “hodl,” and that’s how it became a classic term in the crypto community. HODL means that no matter how much the market swings, you hold on to your coins tightly. BTC drops 15%? Don’t sell. Ethereum crashes? Still don’t sell. That’s the philosophy

I’ve recently been organizing knowledge related to virtual-coin wallets and found that many people are still a bit confused about choosing a wallet. So I’ll share my understanding to hopefully help everyone.
In plain terms, a virtual-coin wallet is a place to store crypto assets. Based on how it works, wallets are divided into two types: cold and hot. Based on device type, they can also be categorized as computer, mobile, online, hardware, and exchange wallets. If you choose the right wallet, you can significantly improve the security of your assets. Most virtual-coin wallets support mainstrea

I just saw something pretty strange. The car YouTuber Chester Car was reportedly exposed for recommending an investment scheme in his story highlights: 2% monthly returns, 24% annual returns, principal protection, and a minimum investment of 500k. At first glance, it looks like he’s selling rare watches, but a lot of people in the comments directly call it a Ponzi scheme—and some even dug up his past, saying he’s basically a scammer.
I checked his background and found out that back in 2017, this guy was involved in the Zhongli shooting incident and was the only survivor. Later, he switched car

When you first enter the crypto world, the most intimidating thing is those technical terms. Opening a position, closing a position, holding a position—these three words probably confuse many newcomers. Let me talk to everyone about these concepts; they’re actually not that complicated.
Let's start with opening a position. Simply put, it means establishing a trading position in the market. If you believe a certain coin will go up, you buy it—that's called opening a long position. Conversely, if you think it will go down, you sell it—that's opening a short position. When opening a position, you

Many people have been trading stocks for years but still can't understand turnover rate; honestly, it's a big trap. But I tell you, the turnover rate is actually the most direct way to find the main force. Master this indicator, and you'll see through what the market makers are doing.
Let's start with the basics: the turnover rate is the frequency of stock trading, reflecting a stock's activity level. The simple calculation is trading volume divided by circulating shares multiplied by 100%. For example, if a stock trades 10 million shares in a month, and the circulating shares are 20 million,

Recently, a friend asked me how to use the RSI indicator. I found that many people are actually both familiar with and unfamiliar with this tool. RSI stands for Relative Strength Index, which essentially uses values between 0 and 100 to measure the comparison of upward and downward momentum over a period of time. The closer the value is to 100, the stronger the upward momentum; the closer to 0, the more dominant the downward trend.
The concept I personally use most often is overbought and oversold. When RSI exceeds 70, the market is often overly optimistic, and a pullback is likely; conversely

Friends who just entered the crypto space might get dizzy from all kinds of jargon. Today, I’ll organize some common concepts and explain what the crypto world is, along with its various ways to play.
Let’s start with the most basic. Fiat currency is money issued by the government, such as RMB, USD, and so on, backed only by government credit. The concept of Token is a bit more complicated. Many translate it as “token,” but in the professional blockchain community, a more accurate term is “digital asset” or “proof of rights.” Simply put, a Token represents a form of ownership or rights on the

Recently, I found that many newcomers to the crypto world are still a bit confused about concepts like going long and going short. They often see these terms in market analysis articles but don’t quite understand them. So I’ll organize my understanding here in hopes of helping everyone get started quickly.
First, let’s talk about what “going long” and “long position” mean. Going long is actually very simple: it means you have confidence in the future market trend of a certain coin and believe the price will go up. “Going long” means based on this optimistic judgment, you actually buy this coin

Recently, a friend asked me what those letters like K, M, E, B, T on exchanges actually stand for, and I realized that many beginners might really not be clear. So I decided to organize it, to save everyone from having to Google every time.
Actually, this counting system is very simple; it’s used to represent large numbers. The most basic is 1K equals 1k, which most people probably know. Going higher, 1M is one million, which is 1,000 times K.
Further up is 1E, representing 100 million. Then 1B is one billion. If you ask what 1T is, that’s a trillion level, and this number is already quite hug

Just finished reviewing the latest on-chain data and found that market expectations for the duration of the bear market are adjusting. This is a topic worth discussing in detail.
Looking back at history, the last full bear market was from November 2021 to November 2022, dropping from 69K to 15.5K, lasting 12 months with a 77% decline. Going further back, the 2017-2018 bear market also lasted 12 months, and the 2014-2015 one extended to 14 months. So, based on historical patterns, cryptocurrency bear markets typically last between 9 to 18 months, with a median around 12 months.
What is the curr

Yesterday, the market experienced a fierce wave again, with over 130k traders being forced to liquidate within 24 hours. This number is really quite shocking. I checked some data and found that this wave of cryptocurrency liquidations was mainly due to extremely volatile prices, combined with many people using high leverage to pursue quick profits. As a result, when the opposite wave came, they all got wiped out.
This kind of situation is actually very common, especially when market sentiment is unstable. Once someone is forcibly liquidated, it triggers a chain reaction, with more and more lev
