Have you ever wondered why people talk about 'long' and 'short' when trading cryptocurrencies? At first, it sounds complicated, but in fact, it’s quite simple and is the foundation of most trading strategies.
So, what is long? Put simply, going long means you’re betting on an asset’s price to rise. You buy it at the current price and wait for it to increase, then sell it at a higher price. Simple example: if you believe Bitcoin will rise from $61,000 to $70,000, you buy at $61,000 and wait. When it reaches $70,000, you sell, and your profit is $9,000 (minus fees). This is called a long positio

I just recently learned about Avalanche and found it to be a quite interesting blockchain project. What is Avalanche, and why is it often compared to Ethereum? Actually, it is a Layer-1 platform developed by Ava Labs, launched in September 2020, with a quite unique network architecture.
What impresses me the most is its transaction speed. Avalanche can process thousands of transactions per second, much faster than Ethereum. Additionally, it has significantly lower transaction fees, making it an attractive choice for DeFi applications and payments. Currently, the AVAX price is around $9.02, wit

Recently, I've noticed that many new traders are asking about Bollinger Bands, also known as Bollinger Bands. Actually, what is Bollinger, and why is it so widely used? I'll explain to you in the simplest way possible.
This tool was developed by John Bollinger in the 1980s, and it’s simply three lines drawn on a price chart. The middle line is a 20-period simple moving average, the upper band is the moving average plus two standard deviations, and the lower band is the moving average minus two standard deviations. The interesting part is that these bands are not rigid; they flexibly expand dur

Tết just passed, and I had to face the classic question again: what does it mean to “burn your account”? Haha, you know, this year there are two hot sayings online—one is “you copy Trump’s tail, and Trump copies your house,” and the other is “the unluckiest person in 2025 is someone who follows Trump.” Of course, if you end up losing money, you have to blame yourself—there’s no one else to blame. Anyway, Trump issuing crypto has also made crypto stand out more, so this Tết, more people at home asked me about crypto trading than usual.
I tried to avoid answering because… I’m still stuck, I have

I have received many questions about what an OCO order is and how to use it to manage trades effectively. In fact, this is a super useful tool that many new traders haven't fully explored yet.
Simply put, an OCO order (One Cancels the Other) is a combination of two orders: Take Profit to lock in profits and Stop-Loss to limit losses. The great thing is that when one order is triggered, the other will automatically be canceled. You don't need to wait around or worry about forgetting to cancel an order.
Why do I recommend using an OCO order? Because it helps you three ways: first, it automates t

I’ve received questions from some of you about what bankruptcy is, what forced liquidation is, and the differences between them. Today, I will explain in detail so you can better understand these risks.
Let’s start with what bankruptcy is. Bankruptcy occurs when the funds in your account are no longer sufficient to maintain your current trading positions. This situation corresponds to when your broker sends a margin call request. From many investors’ perspectives, this is already when the account begins to have problems — not only unable to open new positions but also incurring actual losses.

I just realized something interesting — Pepe the Frog, the green character from Matt Furie's 2005 comic 'Boy's Club,' is no longer just a simple meme. It has become an internet emotion icon, ranging from arrogance to sadness, and now it has a completely new life in the cryptocurrency world.
The so-called PEPE — a token on the Ethereum blockchain — is a bold combination of internet meme culture and the crypto world. It has no transaction fees, is entirely community-driven, and that’s what makes it different from many other coins. This PEPE meme coin has attracted a lot of attention from new inv

I recently took some time to revisit Ethereum mining and realized there are quite a few different approaches depending on each person's goals and conditions. You don't always need to invest in a high-end setup to get started.
Interestingly, ETH still ranks second in market capitalization. With the current price around $2.05K, the mining cost is still lower than the value of each ETH mined, so there are profit opportunities. Especially when you look at this figure: 94% of blockchain projects are built on the Ethereum platform, with over 3,000 decentralized applications running on the network. P

I just realized an interesting thing about the current Layer 1 blockchains. If you're not clear on what a Layer 1 blockchain is, simply put, they are the main foundational blockchains that handle their own transactions independently without relying on other networks. Each Layer 1 has its own token used for paying fees, and they also serve as the platform for other applications, Layer 2 solutions, or dApps built on top.
The cool thing about Layer 1 is that it offers security along with significant growth potential. But to understand better, we need to look at their processing capabilities.
Look

I’ve just received quite a few questions about the risks of trading futures, so I decided to share my own experience for everyone to refer to.
First of all, you need to clearly understand what futures are. Simply put, it’s a form of leveraged trading on exchanges, allowing you to predict whether the price will go up (Long) or down (Short). It sounds easy, but in reality, the risks of trading futures are very high—especially for newcomers.
The most dangerous part is leverage. Most exchanges allow up to x100, meaning you only need 1 dollar but you can control 100 dollars. It sounds tempting, but

I just received a question from a friend about how to set a stop loss, and I think this is an extremely important skill that many new traders often overlook. If you don’t fully understand how to set a stop loss, this article will help you grasp it.
What is a stop loss? Simply put, it’s an automatic order to sell an asset when the price drops to a certain level that you have set in advance. For example, you buy Bitcoin at $30,000 and set a stop loss at $28,000. When the price hits that level, the order will automatically execute a sell, helping you avoid further losses.
Why should you care abou

I just remembered an old but fairly dramatic story in the crypto world — back in May 2020, the Tierion (TNT) coin surged by nearly 45% in just a few days, from 0.05 USD to 0.11 USD, and then plunged to 0.03 USD after 10 days. There was no special news—just a few positive comments on social media. That’s a classic example of what a pump is, which many new traders still don’t fully understand.
Put simply, what a pump is: it’s when a group of large investors (called cá mập) begins buying a large amount of coin at low prices, then creates positive information to stir up the community’s FOMO psycho

I just realized something quite interesting about the cryptocurrency ETF market. If you follow altcoin ETF funds, you'll notice they can't keep up with the growth rate of Bitcoin ETFs. It sounds strange, but the reasons are quite logical.
First, regarding supply. Bitcoin ETFs currently hold about 7% of the total circulating supply of Bitcoin — a significant figure. But altcoin ETFs face a different problem. Since the altcoin market is fragmented across hundreds of different projects, accumulating large-scale positions becomes very difficult. Altcoin ETF managers can't easily buy large amounts

The crypto market is currently showing interesting signals as major coins like BNB and Zcash seem to be waiting for the next breakout. BNB is currently trading around $584 with relatively stable activity, while ZEC is at $236 after a previous growth surge. These two assets are in accumulation phases, focusing on clear support and resistance levels.
But what’s truly noteworthy is what’s happening on the market periphery. Emerging projects are gaining increasing attention, especially those utilizing zero-knowledge proof technology to address privacy and data security issues. This technology is

I just thoroughly researched running nodes to earn money and want to share some interesting discoveries I made.
So, what exactly is a node? Simply put, it is a (computer or server) that helps store, process, and transmit data within the blockchain network. Each node maintains a copy of the data, validates transactions, and sends information to other nodes. This is how blockchain can operate in a decentralized, transparent, and secure manner.
The way nodes operate isn't too complicated either. When a transaction is sent, the node receives it, forwards it to a validator or miner, who then confir

Strike received a BitLicense from New York in March, allowing them to provide Bitcoin services to 8.3 million New York residents. This is considered one of the most stringent regulatory licenses in the U.S., so Strike obtaining it is a notable sign of the maturity of compliant Bitcoin infrastructure.
A curious event occurred at the same time: Samson Mow, CEO of JAN3 and a prominent Bitcoin advocate, publicly challenged the narrative of Bitcoin scarcity that Michael Saylor from MicroStrategy often mentions. Mow pointed out that having a fixed supply of 21 million coins does not necessarily crea

I just saw news about the Lighter derivatives platform - the Bitcoin price there suddenly dropped to $47,510 due to very low liquidity. This event was caused by a large whale who directly pushed 1,000 BTC through the exchange's order book.
In fact, this is related to the so-called cap wall or maximum price limit on the platform - when liquidity is insufficient, prices can be pushed up or down very sharply. That’s why understanding what a cap wall is is important for traders, as it directly affects price stability.
Lighter officials later explained that this was a technical issue caused by limi

I just noticed that SOL shows a buy signal with the TD Sequential appearing after a period of exhaustion from the downtrend, but the price is still not very certain. Currently, SOL is recovering from around $100 up to about $104, but it is being held back by the descending regression line. Overall, this is a controlled rebound, not a trend reversal.
The interesting part is that the MACD remains below zero, but the histogram is flattening, indicating that selling pressure is weakening. Combined with this, the spot taker buy dominance (buyers actively matching orders) suggests that buyer dominan
