Recently, while studying U.S. stock trading, I found that many people actually overlook the pre-market trading session. Honestly, if you want to gain more advantages in the U.S. stock market, pre-market trading is definitely an opportunity worth paying attention to.
Let's first talk about what it is. U.S. pre-market trading is the period before the New York Stock Exchange and NASDAQ officially open, during which investors can buy and sell stocks in advance. It usually starts at 4 a.m. Eastern Time and lasts until the official opening at 9:30 a.m. This period doesn't seem long, but its power is

I've been seeing people ask lately whether the Australian dollar will continue to fall, and I've been paying attention to this question as well. To be honest, the performance of the Australian dollar over the past two years has indeed been somewhat disappointing. From 1.05 at the beginning of 2013 to now, it has depreciated by over 35% in ten years, which is relatively poor among major global currencies.
The reason for the weakening of the Australian dollar mainly results from several overlapping factors. First, Australia's economy is highly dependent on exports of bulk commodities like iron o

Yesterday, the on-chain monitoring community erupted in uproar. Someone discovered that an early wallet address attributed to Satoshi Nakamoto suddenly had a transfer record. Since Bitcoin’s birth in 2009, this address had not moved at all; the unusual activity immediately shot it to the top of Twitter’s trending searches.
According to on-chain data, the address first received a test transaction of 0.0001 BTC in the morning, and then, in the afternoon, transferred 1 BTC out to a hot wallet of a major exchange. The whole process looks like someone is testing the wallet’s usability. Roughly 0.99

Recently, I was asked about registering overseas accounts again. To be honest, this scenario is really common—when you don't want to get a new SIM card, just use a virtual number temporarily. I've run into many pitfalls before; some SMS platforms simply don't receive messages, others have delays of half a day. Only later did I figure out which ones are reliable.
In fact, SMS receiving platforms are services that rent virtual phone numbers to receive verification codes, covering various country codes. After registration, just select a country number and bind it to the target website; the verifi

I've been thinking about a question lately: when many people enter the crypto market, they often struggle with a choice—should they use an exchange wallet or set up their own DeFi wallet? These two methods are actually quite different.
Speaking of DeFi wallets, simply put, they are non-custodial wallets where you hold your private keys. The biggest difference from exchange wallets is that you truly own your assets. DeFi wallets allow you to participate in various innovative market opportunities, such as trading NFT art, engaging in some new derivative projects, and even supporting certain DeFi

Recently, I’ve been researching fingerprint browsers and found that MoreLogin is pretty good. Basically, it allows you to create multiple independent browser environments on one computer, each with a unique fingerprint signature, so websites can't detect that you're the same person operating them.
For those who need to manage multiple accounts, the fingerprint browser’s synchronization feature is very practical. You can control multiple windows with one click, greatly improving efficiency. No need to repeat the same operations; once the main window is set up, the others can follow suit automat

Recently, I’ve been looking at questions from beginners and realized that many people still have a vague understanding of the concept of altcoins. Actually, to put it simply, altcoins is the general term for all cryptocurrencies other than Bitcoin. Most of the early ones were derived by copying Bitcoin’s code, which is why they got this name.
But now, this term is outdated. With the development of blockchain technology, each project has developed its own unique ecosystem and applications. Those emerging public chains and tokens are now on a completely different level of innovation. So nowadays

Recently, I watched some interviews with Duan Yongping. This guy’s net worth is in the hundreds of millions, yet his lifestyle is unbelievably simple—every day he just eats hamburgers, plays golf, and sleeps. At first glance, it looks like he’s “lying flat,” but if you look more closely, you’ll realize it’s absolutely not the case.
He is the only Chinese disciple of the “Warren Buffett lunch,” and the two people’s lifestyles are actually quite similar. Buffett has been drinking Coke for decades, while Zuckerberg wears the same gray T-shirt every day. Many people think this is being stingy, but

I only recently truly understood why the Bee Dog meme is so popular. At first, I thought it was just a funny picture of a dog getting stung by bees and his face swelling up, but I later realized there’s a deeper cultural meaning behind it. In Japanese, honey is 「はちみつ」, abbreviated to 「はちみ」, which Chinese netizens transliterated as “hajimi,” and this word has gradually evolved into an independent meme in our online culture. The 모습 of the Bee Dog after being stung, looking pitiful yet strangely amusing, is like how we appear after being hit with various setbacks in real life — face swollen, but

I recently came across a very interesting人物 story, about the rise of a certain big shot in the cryptocurrency world. After reading it, I finally understood what a complete evolution chain from "top student to businessman to coin manipulator" looks like.
This guy scored just over 20 points in high school physics, originally far from being able to get into Peking University. But he used three tricks—hard studying, high school transfer, and a new concept essay contest—to force his way into PKU with a score of 650. This first step was crucial because once the PKU brand was established, the entire

I recently discovered an interesting concept; the word habibi is especially popular in the Middle East. Habibi actually means dear or friend, and it’s a common colloquial expression in daily communication in Arab countries. This down-to-earth way of expression is particularly suitable for meme coin marketing because meme culture itself relies on this sense of closeness and cultural identity to break through.
There’s a project that seems to have caught this point; the team has repeatedly called out habibi, and their Twitter profile picture has also been changed to a related image, seemingly int

Recently, many people have been discussing the concept of hodler, which is actually a very interesting cultural phenomenon within the Bitcoin community. Simply put, a hodler is someone who, after buying coins, resolutely refuses to move them, regardless of how the price fluctuates.
Think about how volatile Bitcoin's price can be. A coin can soar from a few hundred dollars to tens of thousands, and by then, many people have already lost their composure, making millions and immediately running away. But true hodlers won't do that; they are like battling their own desires, forgetting about the up

I just had a beginner ask me what those letters on the exchange represent, and I realized that many people might not understand them. Actually, these unit conversions are quite simple, so today I’ll clarify them for everyone.
The most common ones are these: K stands for thousand, which is 1k; M is million, equal to 1M; E is 100 million; and T is trillion. These units can be seen everywhere on exchanges, especially when looking at market prices and trading volume.
One of the most frequently asked questions is how much is 1b. B stands for 1 billion, so 1B is 1 billion. Some people easily confuse

In the past week, a few fairly interesting things have happened in the crypto world—almost all of them point in the same direction: AI is truly starting to enter the on-chain world.
First, leading exchanges have successively rolled out wallet solutions for AI Agents, and then payment protocols have begun to think about how Agents settle with each other. On top of that, each company is designing things like Skills or Recipes. On the surface, it looks like a race among big players, but if you look more closely, the real change behind it may be a redefinition of what a wallet itself is.

Recently, a trending topic has flooded the internet: the widely known open-source quantitative trading library ccxt has been exposed for secretly embedding a rebate mechanism in its code. In simple terms, when users place orders using ccxt, the trading exchange rebates they would normally receive are quietly taken by the ccxt team. Once this was revealed, the entire community exploded.
How popular is the ccxt project? Over 36k stars on GitHub, and over 93 million downloads on the official Python package manager. Basically, most quantitative trading teams worldwide are using this tool. It suppo

I just saw a pretty shocking news story: the U.S. government confiscated over $400 million in assets from a dark web mixing service, which is quite a large scale.
This dark web service called Helix processed 354k bitcoins between 2014 and 2017, mainly helping dark web drug markets launder money. Operator Larry Dean Harmon pleaded guilty as early as 2021 and was sentenced to three years in prison last November. Recently, the court officially signed the forfeiture order, and now all assets are being seized by the government.
Honestly, it's a bit surprising that such a dark web mixing service has
