I just skimmed through some discussions about Forex on investment forums and saw that many Vietnamese people still feel confused about this market. Today, I want to share some things I’ve learned that might help you understand Forex better and analyze the forex market more objectively.
Actually, Forex is nothing new – it has existed for a long time, closely linked to international trade. But in Vietnam, it’s still quite unfamiliar to many people. The essence of the Forex market is a global foreign exchange trading platform, not concentrated in a specific location like stocks. It is the market

I just realized that many new entrants to the cryptocurrency market don't know how to trade coins effectively. Actually, this is quite normal because trading coins is not just about buying and selling, but requires a clear strategy.
First, distinguishing between trading coins and holding coins is very important. Holding coins means you buy and keep for the long term, while trading coins involves short-term transactions to profit from price fluctuations. These two approaches are completely different, depending on each person's risk appetite and goals.
There are 5 popular trading strategies that

There is an economic indicator that every financial investor should understand, but many people still have only a vague understanding of it. That is nonfarm payrolls, or NFP—one of the most important data points influencing the global market. I’ll share a practical perspective on what nonfarm payrolls are and why they’re considered the “king” of economic indicators.
When people hear about non-agricultural data, many become confused about what it actually is. In fact, nonfarm payrolls are the monthly report on employment conditions in the United States, published by the U.S. Bureau of Labor Sta

I just came across a warning about BO trading platforms, and I really need to share it with everyone. Why? Because thousands of people are losing money on these “traps” without even realizing it.
What is Trade BO (Quyền chọn nhị phân)? Simply put, it’s predicting whether the price of an asset (gold, foreign currency, crypto) will rise or fall within 30 seconds to 1 minute. It sounds easy, but that’s the trap. If you predict correctly, you earn 80–95%. If you predict incorrectly, you lose 100%. Just looking at these numbers is enough to see the problem.
What makes BO trading so dangerous? Mathe

I just realized an interesting thing: most people who lose money in the market aren’t losing due to poor analytical skills, but because they don’t know whether they’re a Trader or a Holder. That’s the life-or-death boundary that very few people explain clearly.
Stock trading isn’t gambling, even if it looks similar on the surface. It’s a real profession built on probability, statistics, and psychology. Traders don’t wait for a company to spend 5 years building a factory before they can profit—they take advantage of psychological fluctuations within the day and within the week to make money.
Th

In 2025, I’ve noticed that more and more Vietnamese friends are interested in how to buy U.S. stocks. Actually, it’s not that difficult, but you need to understand which options are right for you.
One thing I like about the U.S. stock market is that it’s transparent, reputable, and truly profitable. NYSE and Nasdaq are the two largest exchanges in the world, where big companies like Google, Tesla, and Apple are listed. Unlike the Vietnam market, where you can trade continuously with no midday closing, and the market is very large.
But the problem is: there are actually a few ways to buy U.S. s

I just received questions from some new traders about what a margin call is and why they get margin called when trading with leverage. This is a pretty important issue, so I want to share it with everyone.
Simply put, what is a margin call? It is the situation when your margin account drops below the maintenance margin level set by the brokerage. When a margin call occurs, you will receive a warning and need to manage your position; if not, the platform will automatically liquidate it for you.
In fact, margin is a loan provided by the broker so you can trade with a larger amount of money than

Mình vừa nhận ra một điều thú vị về Web3 - thực ra nó không phải là khái niệm mới lạ gì nữa. Từ năm 2014, Gavin Wood (đồng sáng lập Ethereum) đã bắt đầu nói về một internet phi tập trung dựa trên blockchain, nhưng mãi đến gần đây thì Web3 mới thực sự bắt đầu phát triển mạnh mẽ.
Web3 về cơ bản là thế hệ tiếp theo của internet, nơi bạn không chỉ đọc, viết mà còn có thể sở hữu dữ liệu của mình. Điểm khác biệt lớn nhất so với Web 2.0 là sự phi tập trung - bạn không cần phải tin tưởng một công ty nào đó quản lý dữ liệu của mình nữa. Thay vào đó, blockchain sẽ bảo vệ và mã hóa tất cả.

I just realized that many people don't really understand what spread is, even though it directly affects their daily trading costs. So today I want to share some knowledge about this.
Simply put, spread is the difference between the bid price and the ask price of a currency pair. When you want to buy, you buy at the ask price (higher). When you want to sell, you sell at the bid price (lower). This difference is the profit for the broker, and it is also the first cost you pay each time you open a trade.
Spreads are usually measured in pips. For major currency pairs like EUR/USD, 1 pip = 0.0001.

I have just received some questions from newcomers to crypto about what a honeypot is, so I decided to write this article to share my experience. This is truly one of the most common scams you will encounter when participating in the cryptocurrency market.
Basically, a honeypot works like this: bad actors create a fake token or wallet to lure unsuspecting investors to send money in. They often impersonate a legitimate company and promise high returns, but when you buy the token and try to sell, you’ll find that you cannot sell or have to pay extremely high taxes, ranging from 90% to 100%. As a

I just learned this today, it turns out that different exchanges use different units, so I often get confused. To avoid confusion, just remember: 1K is 1k, 1M is 1 million, 1E is 100 million, 1B is 1 billion. The most important one is 1T, which represents a trillion, often seen when talking about the market cap of major coins. Knowing these numbers clearly helps me avoid mixing things up when reading news or tracking prices on exchanges. If anyone still forgets, remember these to be sure.

I just realized that the whitelist is a very important concept that many people in crypto still do not fully understand. It is not only a list of wallet addresses allowed to participate in ICOs or IDOs, but also a truly effective community management tool.
Looking back at token or NFT launch events, the whitelist always plays a key role. It helps projects control who is permitted to participate, thereby increasing security and fairness. Instead of anyone being able to join and get attacked by bots, the whitelist only allows those who genuinely care about the project to buy tokens or mint NFTs.

I just sat down again and realized that RSI is one of the most powerful indicators that many traders overlook in proper usage. What exactly is the RSI indicator? It is an oscillator that measures the speed of price changes over time, created by Welles Wilder in 1978. But the real secret isn't in the indicator itself, but in how we use it.
I see most new traders entering the market when RSI exceeds 70 (overbought zone) or drops below 30 (oversold zone), rushing to press the sell or buy button. That is a huge mistake! Prices can continue to trend, causing RSI to rise to 90 or fall to 10. If you

I've been trading for a while, but there's one strategy that many new traders often overlook – that is short selling. Today, I want to share with you what short selling is and why it’s important in the financial markets.
Initially, what short selling actually is very simple. It’s a strategy where you can make money when the asset’s price decreases. Instead of just waiting for the price to go up to sell for a profit, you can borrow the asset, sell it immediately at the current price, then wait for the price to drop to buy it back at a lower price. The difference is your profit.
In fact, this st

I have received quite a few questions from newcomers to the market about what leverage in forex is, how to calculate it, and whether it should be used. Today, I will share some of my experiences and understanding of this issue.
Simply put, financial leverage is a tool that allows you to control a much larger amount of money than your actual capital. How does it work? Suppose you have $1,000 in your account. With a 1:500 leverage, you can open a trade worth up to $500,000. That means your purchasing power is multiplied by 500 times.
The advantage of leverage is that it allows profits to increas

I just realized something quite interesting when participating in this crypto market. Newcomers often get caught up in situations that the sages call the five poisons of the mind. If you can't overcome these, it's hard to survive long when the market starts to rise.
First is greed. People fear missing the peak, so they cling to everything and chase after anything without a plan. Then there's anger. When facing failure, people tend to get angry, curse analysts, and panic sell. That is a major mistake in the early and middle stages of a bull market.
Ignorance is also a big problem. Many follow t

Today is May 22nd, the day the Bitcoin community worldwide commemorates a legendary event - "Bitcoin Pizza Day." I just rediscovered this story and find it truly thought-provoking.
It all started on May 18, 2010, when a programmer named Laszlo Hanyecz posted on the Bitcoin forum with a simple message: he wanted to use 10,000 Bitcoins to buy two pizzas. At that time, Bitcoin was just emerging, its real value was still very uncertain, and almost no one believed that this "virtual currency" could be used to buy anything.
But that’s what makes it interesting. Laszlo Hanyecz didn’t see Bitcoin as a

Recently, I’ve noticed that many traders still don’t fully understand what POI is, even though it’s one of the most useful technical analysis tools. POI – short for Point of Interest – basically refers to areas on the chart where the price tends to interact strongly. It’s not a complicated concept, but understanding it correctly can help you trade much more effectively.
When we talk about what POI is, we’re referring to areas identified from previous abnormal price movements. For example, huge candles with long wicks, price gaps, false breakouts, or strong supply and demand zones. I often call

I just learned about a pretty interesting Layer 2 project called Scroll. Many people ask what Scroll is, so today I want to share some basic information about it.
Scroll is essentially a Layer 2 solution that uses zk-rollup technology to process transactions off the main Ethereum chain. Instead of all transactions being processed directly on Ethereum, Scroll handles them on its own private network and then submits proof to Ethereum for approval. This approach significantly reduces costs and greatly speeds up transaction times.
What makes Scroll special is that it uses zkEVM, a relatively new t

I just realized that many people in the blockchain community still confuse between mainnet and testnet. Today I want to share about what mainnet is and its importance compared to testnet, because these are truly two fundamental concepts that anyone working with blockchain needs to understand clearly.
What is mainnet? Simply put, mainnet is the official blockchain network where real transactions occur. This is where real money is transferred, NFTs are traded, and all data is publicly stored on the blockchain. When you send Bitcoin or Ethereum on the mainnet, you are conducting a transaction on
