I just saw a security breach on the ARB network, and it’s pretty alarming. According to Cyvers’s data, the attacker exploited a vulnerability in the proxy contract to steal $1.5 million in a single attack, involving the USDGambit and TLP projects.
The attack method was essentially targeting the ProxyAdmin permissions. The attacker deployed their own contract, updated the admin rights, and directly bypassed the original permission restrictions. The $1.5 million USDT on the victim’s address was transferred directly to the attacker’s wallet. I checked the transaction records, and the flow of fund

Recently, I've been analyzing Ethereum's price movement and have noticed some interesting patterns. Over the past few months, the price has been oscillating below $2000, being hammered down along with Bitcoin, and investors seem eager to sell.
I've observed a clear technical pattern: the price has been stuck around $1977 for a long time, with noticeably weak upward momentum. The current trend looks like it's forming a symmetrical triangle, with the price being squeezed between two trendlines. This kind of triangle usually indicates that the market is brewing for a big move, but the direction h

I just recently realized something: many people, including myself, have been neglecting roof maintenance. It wasn't until I saw dark streaks and moss start to appear on my own roof that I truly understood what "small problems become big troubles" means.
Roof cleaning is definitely not just for appearance. I found that algae and moss trap moisture on the tiles, and over time, the entire structure can be damaged. Asphalt shingles can lose their protective layer, wooden shingles may start to rot, and even metal roofs can rust. The most frightening part is if the gutters are clogged with leaves, w

Recently, I came across a quite interesting market trend. An asset management firm submitted an application to the U.S. Securities and Exchange Commission to launch a series of ETF products tracking U.S. election results, called PredictionShares, planning to list on NYSE Arca.
The design logic behind this is actually quite unique. They break down each political election into separate fund products—two funds corresponding to the 2028 presidential election, each based on whether the Democratic or Republican candidate wins; similarly, for the 2026 Senate control and House of Representatives elect

I just noticed that Qualcomm's latest earnings report is quite interesting. Quarterly revenue hit a record high of $12.3 billion, with automotive chips surpassing $1 billion for two consecutive quarters—looking very impressive. But then Wall Street slapped it back, and the stock price plummeted 9% after hours. The only reason? Memory shortages.
Qualcomm CEO Cristiano Amon was very straightforward: "I'm very satisfied with the business; I just wish there was more memory." The second-quarter guidance was cut from $11.12 billion to a range of $10.2 billion to $11 billion, and earnings per share a

I just recently discovered that IG accounts can actually be switched between professional and personal accounts at any time. I wanted to share this little tip.
Previously, I changed my account to a creator account to use data analysis tools and advertising features, but after a while, I realized I didn't really need those functions. I just wanted to share my life simply. Later, I found out that switching back to a personal account on IG is super easy: open the app, go to your profile, tap the three-line menu in the top right corner, find "Creator Tools and Controls" (or Business Tools, dependi

Recently, I've been watching the precious metals market and noticed that both platinum and palladium prices are undergoing a correction, which is indeed a bit tough for short-term traders.
Let's start with platinum. In mid-March, it broke below $2,000, and by the 18th, it had fallen to around $1,945, a decline of nearly 4%. It seems that during the previous rally, many took profits at high levels, which kept the platinum price suppressed. Currently, it’s fluctuating between $1,900 and $2,050. If it can hold above $1,900, there might be a chance for a rebound. On the technical side, Bollinger B

Recently, many people have asked me whether buying a car at the end of the year is really cost-effective. I’ve reviewed the latest used car pricing report and want to share some practical car-buying insights.
First, the conclusion: buying a car at the end of the year isn’t necessarily cheaper than at other times, but there are definitely opportunities to find good deals. The key is doing your homework.
Last year, the average price of used cars rose to $33,718, up 4.6% from the previous year. At first glance, it seems like prices have increased, but the reality is more complex. Some models’ pri

Recently, I’ve noticed an interesting phenomenon in the cryptocurrency market: more and more capital managers are re-evaluating their investment strategies. Many industry insiders emphasize that rather than passively providing liquidity, it’s better to actively participate in market development.
After listening to various experts, including perspectives from well-known capital firms like DWF Labs, Amber Premium, and Edge Capital, I understand why active capital is becoming a new competitive advantage in the crypto space. Kingsley Advani, founder of Allocations, manages $3 billion in capital. H

Toyota officially announced a major senior management change today. Kenta Chika, who was promoted from CFO to President, officially took office today (April 1), while the current President, Koji Sato, has been appointed Vice Chairman. This personnel adjustment actually reflects Toyota's strategic considerations amid the dramatic changes in the global automotive industry.
What’s most interesting is that Kenta Chika’s background is somewhat different from previous presidents. The new president has long led the group’s financial and operational restructuring, especially accumulating extensive exp

Recently, someone asked me what a nonce is in blockchain, so I organized my thoughts and want to share with everyone.
Simply put, a nonce is a "one-time use number" that plays a crucial role in PoW mining. You can think of it as a key in the miner’s hand — they keep adjusting this number until they find a hash value that meets the network’s difficulty requirement. This process sounds simple, but in reality, it involves massive trial-and-error calculations. The computational cost of this process is what ensures the security of the blockchain.
On the Bitcoin network, a miner’s workflow roughly g

Recently, I’ve seen many people in the community asking what APY means, especially when researching DeFi products and staking yields. I think it’s necessary to clarify the concepts of APY and APR, because confusing them can really affect your expectations of actual returns.
Let’s start with the most straightforward difference. APR is the annual percentage rate, simply an annualized percentage without any complicated factors. For example, if you deposit $10,000 with an APR of 20%, you earn $2,000 in a year, and $6,000 over three years. It’s straightforward and linear.
APY means something comple

I just realized recently that a VPN is what a "ladder" refers to. Many on-chain activities have restrictions in the Chinese region, so you have to use a VPN to bypass them. If I use an Apple device, I first register a foreign Apple ID—just go to the official Apple site, don't buy anything, and register via iCloud, choosing Hong Kong or the US. I’ve set up two accounts like that. Once you have a foreign Apple ID, you can download VPN apps like ExpressVPN or Shadowrocket. ExpressVPN is relatively easy to use; after payment, one account can be used on two devices. For Android, it’s more complicat

Many beginners often get confused by the letter units when viewing charts on exchanges. Let me organize the common measurement units for you.
Actually, the most basic units in exchanges are these: K stands for thousand, so 1K equals 1,000; M is million, so 1M equals 1,000,000; then 1E represents 100 million, which is especially common when looking at market cap or total volume; B is billion, so 1B equals 1 billion; the largest unit T stands for trillion, so 1T is 10,000 billion or one trillion.
In practical operation, you'll find that when viewing a coin's market cap or circulating supply, you

I recently came across an interesting news story: Saudi Arabia has discovered a major gold deposit in the Mecca region—this could be more significant than it appears on the surface.
The authorities just announced that they found over 200 tons of high-grade gold in the southern Mansaura-Masara mining area, making it the largest discovery in the kingdom in decades. The timing of this discovery is quite critical, with exploration scheduled to be completed between late 2023 and early 2025, perfectly aligning with the progress of Saudi Arabia's Vision 2030.
I see this as more than just a mining new

Recently, many people have been asking me about the ranking of cold wallets. Choosing a reliable wallet is indeed crucial for asset security. Instead of keeping your coins on an exchange, many experienced users prefer to store them in a cold wallet to truly control their private keys.
Speaking of cold wallets, they are essentially offline devices used to store crypto assets, kind of like putting a lock on your digital assets. There are quite a few options on the market, so I’ll highlight some of the more well-known ones.
Trezor is a veteran in this field, a Czech brand that has put a lot of ef

Do you remember the 519 Crypto Bubble Event? Five years have passed, and those seasoned investors who experienced that black swan event probably still recall the heart-pounding moments. Overnight, countless people's dreams of sudden wealth were shattered in an instant. The thrill of such dramatic ups and downs was truly exhilarating. Looking back now, the unprecedented crash on May 19, 2021, has become one of the most iconic cases in cryptocurrency history.
Let's start with the trigger of this storm. Everyone knows how influential Elon Musk is in the crypto world. In Q1 2021, he led Tesla to b

Recently, I saw that Ko Wen-je's cold wallet was seized by prosecutors and is still under investigation. This incident reminded me of a common misconception: Are cold wallets really that secure?
Actually, cryptocurrency wallets aren’t that mysterious. Simply put, they are digital containers used to store, send, and receive virtual assets. The core of a wallet consists of three things: private keys, public keys, and addresses. Among these, the private key is the most critical because only the holder of the private key can access the assets in the wallet. That’s why private keys must never be di

Recently, while analyzing the charts, I noticed that many novice traders still have a superficial understanding of the RSI indicator, especially when it comes to setting RSI parameters, which often leads to pitfalls. Today, I want to share some of my practical observations about RSI.
Speaking of RSI, it’s essentially using a value between 0 and 100 to measure the strength of upward and downward movements over a certain period. Simply put, when the upward momentum is strong, the value rises; when the downward momentum is strong, it falls. The most straightforward use of this indicator is to ide
