I just want to share a security issue in smart contracts that many developers often overlook — reentrancy attacks. If you're building smart contracts on Solidity, this is something you must understand thoroughly.
Simply put, reentrancy occurs when a contract calls another contract, and that called contract can call back into the original contract while it is still executing. Imagine you have ContractA holding 10 Ether, and ContractB sends 1 Ether to it. When ContractB withdraws funds, ContractA checks if the balance is greater than 0, and if so, sends Ether back. However, if ContractB has a fa

I just realized that many people do not fully understand how trading gold on Forex actually works. Today, I want to share a few things I’ve learned through my trading experience.
First, you need to understand that gold is traded as XAU/USD. XAU represents one troy ounce of gold, and USD is the US dollar. Its price reflects how much money you need to buy one ounce of gold. Why is gold attractive? Because it acts as a hedge against inflation and currency devaluation. When the market is unstable, people flock to gold, causing its price to rise. Additionally, the gold market is one of the most liq

Looking at the current cryptocurrency space, I see that Web 3.0 coins are becoming one of the most notable trends. If you still don’t fully understand what Web 3.0 is, simply put, it’s a completely new way of using the Internet, where your data truly belongs to you, not big corporations.
The great thing about Web 3.0 is that you have full control over your data. Instead of Facebook or Google owning everything, now you can decide to sell or keep your information private. And to access services within this ecosystem, you use tokens running on a public, decentralized blockchain.
I’ve been followi

I just noticed that the global meme community is focusing on a new project — Puppy. Meme enthusiasts related to Elon Musk from all over are collaborating to build this token, with strong consensus from both the English and Chinese-speaking communities.
Why does it have potential? Puppy combines three main factors: first, Elon Musk and his mother have shared dog photos multiple times on social media, and dog-loving images have deeply ingrained themselves in users' minds. Second, the history of Elon Musk-related meme coins is truly impressive — LADYS once reached a market cap of $100 million wit

I just saw some friends debating what Web3 is and how it really differs from the regular internet. So today, I want to share what I understand about this trend.
Looking back at history, the internet has gone through two phases. Web 1.0 in the early days was just static pages, then Web 2.0 came along with Google, Facebook dominating everything. These companies control our data, decide what we see, and we have no rights. So what is Web3 now? It’s the next step, where users truly have control over their data and assets without needing an intermediary.
The foundation of Web3 is blockchain — a tran

Today is May 22nd, and anyone in the crypto community knows what that means – it's a day to remember one of the craziest transactions in financial history. I just scrolled through and saw people sharing about Pizza Day, and every time I see it, I feel crazy about that number.
The story is actually quite simple. In 2010, a programmer named Laszlo Hanyecz from Florida was craving pizza. Instead of ordering normally, he posted on the Bitcoin forum saying he was willing to pay 10,000 BTC for two large pizzas from Papa John's. At that time, 10,000 Bitcoin was worth about $40. Someone accepted, used

I recently paid attention to an interesting project in the DePIN space—Parasail Protocol— which has just completed a $4 million seed funding round, valuing it at up to $50 million. What draws attention is that the list of investors is quite strong, including Protocol Labs leading the round together with D11 Labs, MH Ventures, BitRise Capital, EV3, Fenbushi Capital, and many other funds.
The strength of Parasail is that it solves a real problem in DePIN—how to make hardware services run more securely and efficiently. Instead of each DePIN project having to build its own system, Parasail provide

Already entered the crypto world but still confused by slang terms? Don't worry, you're not alone. I'll explain the strange words people often use in the community.
Starting with the basics. Have you heard of aping? That’s when someone buys a token immediately after it launches without doing any research. Then there’s bagholder — those who hold onto assets even as the price crashes. They believe the price will recover, or simply fear admitting defeat.
There’s a group called Bitcoin maximalists — people who believe Bitcoin is the only cryptocurrency with value. BTD stands for buy the dip, meani

I just noticed that silver (XAGUSD) has returned to the $80 level, which is quite interesting because it was previously "wiped out" during a severe margin liquidation. A few days ago, silver plummeted from $82.77 down to $73, a 10.7% drop in a single move. The reason was CME unexpectedly increasing margin requirements, forcing many highly leveraged investors to close their positions. Now it has bounced back to the $80 level, which seems to be a significant recovery after the shock.
Last night's non-farm payroll data also gave silver this opportunity. Only 50,000 jobs were added, and the figure

I just realized that understanding pullbacks can completely change the way you trade. It’s not just a theoretical concept but a key to finding safe entry points and optimizing profits.
A basic pullback is a temporary price correction when the market is in an uptrend or downtrend. Think of it as the market "breathing" a little before continuing in the main direction. Why is this important? Because it allows smart traders to "buy low" in an uptrend or "sell high" in a downtrend, rather than chasing breakouts with higher risk.
Recognizing a quality pullback isn’t too complicated. First, you need

Yesterday, I talked with a friend about account security, and they asked why 2FA codes are so important. I think this is a good time to share because too many people still only use passwords.
The reality is that a password alone is no longer enough to stay safe. Hackers can guess, steal, or obtain your password from data leaks. Moreover, many people reuse the same password across multiple sites, which increases the risk. That’s why 2FA codes were created.
Simply put, 2FA adds an extra layer of protection. When you log in, you not only need to enter your password but also provide a second piece

I’ve just compiled a few great books about crypto that I want to share with everyone interested in this field.
Honestly, when you first step into the world of cryptocurrencies, the hardest part is finding reputable materials to learn from. I’ve read quite a few crypto books and found that a few are truly worth it.
The first one to mention is "The Bitcoin Standard" by Saifedean Ammous. This book thoroughly explains the history of Bitcoin since its inception in 2008. Ammous is an economics professor, so his writing style is quite academic but easy to understand. This book is valuable because it

Recently, I saw that on Solana there’s another meme coin CR7 – it skyrocketed to $5 million in just a few hours, but then almost completely collapsed. This one is inspired by Cristiano Ronaldo, but has nothing to do with him at all.
The crazy thing is that the token was launched early on August 26, and within six hours, there was significant trading, with a cumulative volume of up to $55 million. But boom, the market cap dropped straight down to $359,000. That’s the classic scam pattern I’ve seen too many times.
This CR7 meme coin isn’t the first time. Previously, another fake CR7 token reache

What is Hyperverse and why does it raise concerns? I just looked into this cryptocurrency project and truly feel the need to warn everyone.
The crypto world is always full of opportunities, but it also harbors numerous risks. Hyperverse is one of the recent projects that has caused confusion—some people are excited, while others are skeptical. The main question is: is this a scam?
To answer that, we need to carefully examine multiple aspects. First is legality and warning signs. When evaluating any project, due diligence is essential. You should check the project's whitepaper, tokenomics struc

I just explored some free AI trading tools and want to share a few that I find quite useful. Actually, there are quite a few options available if you want to use AI to assist with trading.
Starting with TradingView, most traders are already familiar with this. Besides basic charting features, it offers smart indicators and allows you to write scripts in Pine Script to automate your strategies. The great thing is that it enables backtesting before going live. The free version already has many features, and the pro version adds more advanced tools.
There's TrendSpider if you want AI to automatic

Have you heard this story? I just found out that the famous female actress from the HongKong Doll film is actually a Web3 expert who’s been in the game for a long time. The wild part is that a few years ago, she short-sold ETH in a massive amount, and people are rumored to have made more than 100 million from that deal. But recently, there’s shocking news—her crypto wallet is basically back to 0. I was so curious that I went back to look into the history.
Actually, since 2022, she’s been getting involved in the NFT scene when Azuki was still really hot. At one point, she tweeted about buying a

I've just realized that many people still confuse CEX and DEX, even though these are two fundamental concepts in the crypto world. Today, I want to share what I've learned about these two trading models.
Most of us start with CEX — centralized exchanges. The reason is simple: it's easy to use. You sign up, complete KYC, deposit funds, and start trading immediately. User-friendly interface, high liquidity, and support available if you encounter issues. But the price of this convenience is that you have to trust the exchange to hold your assets. If the exchange gets hacked or goes bankrupt, you

I just looked at the BTC price and found something interesting. Currently, BTC is at $66.90K, much higher than previous predictions. This makes me want to share a concept that everyone involved in crypto should understand — what is a bull run and how does it affect the market.
What is a bull run? Simply put, it’s a period when most investors are optimistic, demand exceeds supply, market confidence is at its peak, and prices are continuously rising. When you see prices trending upward rapidly in a certain market, it could be a signal that investors are becoming more positive about future prospe
