Do you have questions about what forex spread is? I just realized that quite a few people don't fully understand this concept, even though it's very important when trading.
Simply put, the spread is the difference between the bid price and the ask price of an asset. Imagine you're at a market: the buyer wants to pay 90 rubles for an apple, while the seller wants to sell at 100 rubles. That 10-ruble difference is called the spread. This applies to everything — stocks, forex, cryptocurrencies — they all have spreads.
Why is it important? A small spread means easier transactions, high liquidity a

Recently, I’ve been quite curious about a concept that’s been popular in the blockchain community — Proof of Humanity, or PoH for short. So, what exactly is PoH? Simply put, it’s a way to verify that you are a real person through blockchain, not a bot or some automated system.
Unlike traditional Proof of Work or Proof of Stake, PoH focuses on proving the “humanity” of users. Its operation is quite interesting — users must submit their profiles and undergo a verification process carried out by the community. Other users will check whether the person in the profile is a real human, usually throu

I just realized that in the crypto community, the concept of shill is something that many people misunderstand or overlook. Simply put, shill is a vigorous promotional campaign aimed at creating positive attention for a particular project or cryptocurrency, often through social media, online forums, and other platforms.
The danger of a shill coin is that it creates a temporary price bubble. Many times I see a coin suddenly appearing everywhere—KOLs promoting it, continuous positive articles, people discussing it. But when you look closely, that project isn’t particularly special. That’s a sign

I just noticed a pretty interesting concept in the crypto world that many people still haven't fully understood — which is what token burning is. It might sound strange at first, but once you understand the logic behind it, everything will make sense.
What is token burning? It’s simply the act of permanently removing a certain amount of tokens from circulation. Projects send these tokens to a wallet address that no one has the private key for access, effectively deleting them from the crypto universe forever. It’s like traditional companies buy back their shares, but in the blockchain world, t

I just realized something interesting: the herd mentality in crypto is so powerful that it causes many people to lose control of themselves. Have you ever found yourself rushing to buy just because everyone is saying "it's going up"?
The so-called FOMO is truly the biggest enemy. When BTC or any altcoin starts to rise, the timeline suddenly fills with stories of huge profits. People brag, and you feel like you're missing out on an easy money opportunity. But that’s exactly when it’s most dangerous. I’ve seen many newcomers buy at the top just because they’re afraid of missing out, only to get

I just heard a crazy story about Web3 that I have to share with you guys. Did you know, HongKongDoll - the internet famous girl - is actually a seasoned crypto player? Not only that, she also caused a storm in the NFT and futures markets.
In early 2022, when NFTs were still hot, HongKongDoll suddenly tweeted about buying a large amount of Azuki - a well-known blue-chip NFT project. The crypto community was buzzing at that time, and the price of Azuki skyrocketed from 3 ETH to 30 ETH by April. Everyone believed she made huge profits from it. But then, HongKongDoll revealed an even more notable

I want to share a tool for analysis that I frequently use: Bollinger Bands. If you don't know what BOLL is, it's a pretty useful technical indicator developed by John Bollinger in the 1980s.
Basically, the Bollinger Bands indicator consists of three lines drawn on a chart. The middle line is a simple moving average (SMA) calculated over 20 periods, representing the average price over a certain period. The other two lines—the upper and lower bands—are calculated by adding or subtracting twice the standard deviation from the middle line.
What’s the advantage of BOLL? It helps you measure market

Hearing the word 'Bubble' will make you think of hot water balloons gradually inflating, then getting bigger, and finally bursting. The crypto market is the same. I notice that the price of a certain coin or project will spike in a short period, then sharply decline again. It’s simply that market demand at that time far exceeds their true value.
Everyone sees the price rise and gets excited, without researching thoroughly and rushing to buy. This coin bubble keeps inflating more and more. I see three main reasons leading to this.
First is FOMO - the fear of missing out. When you see others mak

I just heard some people discussing Mina Protocol, and I realized that what Mina is still remains a fairly unclear question for many of you. In fact, this is one of those blockchain projects that I think is worth looking into in more detail.
There is something quite unusual about Mina Protocol—it’s a Layer-1 blockchain, but its size is extremely small, at only about 22KB. For comparison, that’s the size of just a few tweets. Can you imagine? While Bitcoin and Ethereum keep getting bigger, Mina keeps its size fixed thanks to zero-knowledge proof technology (zk-SNARK). This allows anyone, even u

ixxxx, I took quite a big risk back then. Bought in two years ago, and now the capital has tripled. Actually, the projects I chose are all quite strong – Solana, Aave, Hbar, Near, all have good signals. But honestly, most of the profit came from meme coins like Shiba and Pepe, which was surprising. ixxxx is one of my most risky decisions, but the result wasn't bad. I was really scared at first, but just held and waited, then saw it go up. Now I still hold those projects, and ixxxx is still on my watchlist. How about you guys, are there any coins that unexpectedly turned profitable?

I just realized something quite interesting: the difficulties of investing in crypto are actually very similar to the psychological traps Buddhist scholars have warned about for thousands of years. Specifically, what are the five poisons—greed, anger, ignorance, pride, and doubt—if not things that have a major impact on our trading results?
Looking at a rising market, the clearest one is greed. When prices go up, everyone is afraid of missing the peak, so they just keep buying more and more without stopping. That’s attachment—greed: wanting to reap everything, while forgetting that no one ever

Getting started in Crypto, I realize there are so many ways to make money from this market. But when it comes to trading, most people only know about 2 main methods: Spot and Futures. So what is spot trading and how does it differ from Futures? Today, I will explain in detail for you.
The most basic difference is here: when you trade spot, you actually buy coins into your wallet. For example, I have 20 million VND, I buy Bitcoin with that amount, and at that moment, Bitcoin is truly mine. If the BTC price rises to 30 million, I sell and make a profit of 10 million. If the price drops to 10 mil

I have just summarized some basic principles of Elliott waves that many people often overlook when counting waves. This Elliott wave counting method is quite useful for identifying the right entry points, especially when the market is experiencing strong volatility.
The most important thing is to remember these three fundamental rules, which must never be violated under any circumstances. First, wave 2 can never retrace more than 100% of wave 1 — this is a mandatory condition to validate an Elliott wave. Second, wave 3 cannot be the shortest among the three impulse waves (waves 1, 3, and 5) —

I just realized that many new traders entering the futures market do not understand a fundamental but very important concept – the Funding Rate. This can really have a significant impact on your profits, especially if you often trade perpetual contracts.
Basically, the Funding Rate or funding fee is a periodic interest payment exchanged between those holding Long and Short positions. Its main purpose is to keep the futures price from diverging too far from the actual spot market price. It is calculated based on the price difference between these two markets and is usually expressed as a percen

I just learned more about these units on the exchange, and it turns out many people still mix them up. If 1b is how much, then it’s exactly 1 billion—that is, 1 thousand million. Usually you’ll see people write 1K as 1000, 1M as 1 million, 1E as 100 million, and 1B as 1 billion. Anything higher is 1T, which is equivalent to 1 thousand billion (that is, 1 nghìn tỷ). Knowing this helps when reading volume or market cap on exchanges, so you don’t misread the numbers. I’ve noticed a lot of new users get confused by these symbols, so I’m sharing this to be sure 😄

I see many newcomers to crypto often ask what futures are and whether they should participate. Today, I want to share some practical experiences on this topic.
Basically, futures are a leveraged trading method that almost all coin exchanges support. Its essence is predicting whether the price trend will go up (Long) or down (Short), then placing an order based on that prediction. If you're correct, you make a profit; if you're wrong, you incur a loss. It sounds simple, but in reality, the risks are quite high, especially for beginners without experience.
The most dangerous aspect is leverage.

I just delved deeper into zkSync (ZK) and found that it is truly an interesting layer-2 solution for Ethereum. Its advantage is using zk-Rollup technology to process transactions off-chain, only recording the necessary data on Ethereum, thereby reducing load and significantly increasing speed.
What is ZK that makes it so hot? Essentially, it is the governance token of zkSync, issued with a total supply of 21 billion (recent update). Currently, the ZK price is around $0.02, with a circulating market cap of approximately $148.75M. Although it decreased by 0.38% in the past 24 hours, this is quit

I just learned about Cookie3 and found it quite interesting. This is a pretty unique MarketingFi platform built on an AI Data Layer to create a transparent marketing system for Web3. Currently, more than 300 applications are using their technology.
The cool thing here is the project's COOKIE token. COOKIE tokens are not only used to unlock products, services, and airdrops on the platform, but holders also have governance rights and can participate in decision-making for the entire ecosystem. It's like you're not just a user but also an owner.
What I noticed is that Cookie3 has built a fairly c

When do you always wonder why a stock cannot rise or fall infinitely in a trading session? That’s because of the ceiling price and floor price—two important concepts that anyone trading securities in Vietnam must understand clearly.
The ceiling price is the highest level that a product can reach during a session, while the floor price is the lowest. They are calculated in advance based on the reference price (the previous session’s closing price) and the fluctuation margin. An example of ceiling and floor prices in practice is quite common—for instance, HPG stock with a reference price of 24,0

Since observing the development of Layer 1 blockchains, I have noticed that Near Protocol is becoming an exciting competitor to Ethereum. It’s not just about the technology but also a different approach to development than what people expect.
Near Coin is the token of the Near Protocol system used for transaction fees and staking rewards on the network. The coin supply is limited to 1 billion coins, which could impact its future value.
What makes Near different is the sharding technology used in the system. This allows it to support a large number of transactions quickly, and the gas fees are
