Recently, while exploring DeFi products, I noticed that many people are confused about the concepts of APY and APR. Actually, I was initially confused myself. Today, I want to share my understanding in hopes of helping everyone.
Simply put, what is APY? It’s the annual percentage yield, which takes into account the effect of compounding. APR is the annual interest rate, excluding compounding. These two may seem similar, but in reality, the difference is quite significant.
Let’s start with APR, which is relatively straightforward. Suppose you deposit $10k on a platform with an annual interest r

I've been a bit annoyed lately with virtual numbers. Registering for overseas websites and testing APIs all require phone numbers, but I don't want to expose my real number. I later discovered SMS verification platforms, which are really convenient. Basically, you rent a virtual number to receive SMS verification codes, supporting various countries and regions, with pay-per-use or monthly plans.
I've encountered many pitfalls before—some platforms can't receive verification codes at all, others are painfully slow. In the end, I summarized five decent SMS verification platforms that I personall

The signals from the stock market and futures over the past few days have been somewhat pessimistic, and it looks like there may be downward pressure on the stock market before the weekend. I’ve come across many analyses saying that after this week's turbulence, everyone's mindset has become more cautious, and market sentiment is noticeably weaker.
Thinking carefully, the current economic data and international situation are indeed a bit complicated, and these factors are all influencing investors' decisions. It feels like the risk of a stock market decline in the coming period needs to be pai

I recently observed a phenomenon in the crypto world: many newcomers are trying a method called "撸毛" (literally "farming毛" or "毛 farming"). To be honest, at first, the name was a bit confusing, but after understanding it more deeply, I realized it’s essentially about participating in various activities and benefit mechanisms offered by project teams to acquire cryptocurrencies at minimal or zero cost. For newcomers, "撸毛" is often the first step into the blockchain ecosystem.
Why do project teams give out tokens voluntarily? Basically, it’s to attract users, generate buzz, and build traffic. Th

I've been thinking about this recently: how to build a relatively balanced cryptocurrency investment portfolio. There’s no absolute answer, but some ideas are definitely worth considering.
I’ve noticed that many people tend to go to extremes when allocating crypto assets—either putting everything into major coins or betting entirely on small-cap tokens. In fact, the best crypto portfolio allocation should be a hybrid strategy, allowing you to enjoy the gains from market uptrends while managing risk.
From my observations, Bitcoin and Ethereum are still the foundation; these two are the bedrock

Recently, I came across a pretty interesting phenomenon—Litecoin, Solana, and XRP are all submitting ETF applications. A lot of people ask me what an ETF is. In fact, that’s a great question, because once you understand what an ETF is, you can make sense of the logic behind this round of moves.
First, let’s talk about what an ETF is. Simply put, an ETF (Exchange-Traded Fund) is an exchange-traded fund that is listed and traded on a securities exchange. It combines the diversification of a fund with the flexibility of stocks. You can buy and sell it anytime during trading hours, just like stock

Recently, I needed to register a bunch of overseas accounts, and dealing with various SMS verification codes was a headache. Later, I found out about the SMS receiving platform, which saved me a lot of trouble. Basically, it’s using virtual numbers to receive SMS—no need to buy a new SIM card—and it also protects your privacy.
I’ve tested a few Chinese-number SMS receiving platforms myself, and I ran into plenty of pitfalls. Some simply couldn’t receive the verification code, others had a delay of half a day. In the end, I found a few that were pretty good—SMS-Activate is the fastest, and the

Recently, I noticed an interesting development with the XRP spot ETF. On March 5th, the US XRP spot ETF experienced a outflow of $6.15 million, marking the first single-day net outflow since mid-February. Although there had been some small withdrawals before (around $2.22 million), this outflow was significantly larger.
This signal is actually worth paying attention to. After several weeks of steady net inflows, such a sudden shift more or less reflects a subtle change in investor sentiment. While the amount isn't large compared to Bitcoin ETF inflows, for XRP ETF investments, transitioning fr

Recently, I watched videos of the Zhanjiang Mazu worship rituals, and many people are asking: why do they keep tossing that crescent-shaped object repeatedly? Actually, this is called casting the Holy Cup, or casting the Jiao, which is essentially an ancient way for people to communicate with the gods.
This thing looks simple, but there are many nuances behind it. A pair of Jiao cups, one flat side and one convex side—how they land indicates different meanings. If both cups land with the flat side up, that’s the Holy Cup, meaning the gods agree, approve, and the matter can proceed. If both lan

Recently, a big scandal has rocked the crypto world again. The Epstein files released by the U.S. Department of Justice surprisingly contain some clues about Bitcoin, and people have started digging through these emails, trying to find traces of Satoshi Nakamoto’s identity.
I looked over these uncovered emails, and they are quite interesting. One email is from Epstein to the Saudi Royal Court and the Abu Dhabi Department of Culture and Tourism, where he suggests they develop digital currency and casually mentions that he has already communicated with the Bitcoin founder, who responded very pos

Recently, I’ve been researching the ROBO project, and the logic is indeed interesting. The x402 protocol defines the valuation and settlement methods between machines. As a protocol-layer asset, ROBO’s value isn’t based on hype but on actual trading volume and use cases. Every time a machine completes a transaction using the x402 protocol, it consumes ROBO to pay the fee. To become a node, you need to stake, and holding ROBO is also required for governance participation. This mechanism determines its underlying value logic.
By the way, there have been more and more airdrop projects lately. OPN

Recently, someone asked me about crypto wallet addresses, and I realized that many beginners actually don’t quite understand this concept. Today, let’s talk about this fundamental but very important topic.
Put simply, a wallet address is your identity on the blockchain, a bit like your bank account number. Without a wallet address, there’s basically no way to send and receive funds on-chain, so this is still pretty critical. The address formats for each coin are different—for example, Bitcoin addresses are usually 26 to 35 characters, starting with 1, 3, or bc1. Ethereum addresses are 42 chara

Recently, I needed to do some account testing and realized how convenient SMS reception platforms are. Instead of buying new SIM cards, it's much easier to use virtual numbers directly. After trying several platforms, I finally found some reliable ones—I've encountered countless pitfalls along the way.
The first platform I used couldn't receive SMS messages, and the next one had delays of half a day. In the end, I summarized a few decent SMS reception platforms. SMS-Activate is used the most; verification codes arrive within about 10 seconds, with full country coverage, making it especially su

I've been closely following U.S. trade policies lately, and Trump's tariff policies have indeed become a focal point in the market. At that time, the Supreme Court was set to rule on the legality of tariffs on steel and aluminum, which caused quite a stir among traders.
The consensus in the market was that there was a significant chance the court would overturn these tariffs. This was not just a legal issue; it involved the overall direction of U.S. economic policy. Trump viewed these tariffs as a key tool in his trade war strategy, aiming to protect domestic industries and gain leverage in in

After years of trading, I’ve realized that one of the most overlooked aspects by beginners is the correct calculation of PnL. Don’t underestimate this as just a simple concept—mastering it can save you a lot of unnecessary losses.
Let’s start with the basics. PnL stands for profit and loss, reflecting the change in your position’s value over a period of time. But there’s a lot of complexity behind it, not just a rough calculation of buy price minus sell price. Many traders get confused about the difference between realized and unrealized PnL, which leads to confusion about their account status

I looked at the 15-minute chart of ETH, and this wave is pretty good. It’s been steadily climbing past previous highs, like drawing lines with a ruler. Each pullback finds support near the yellow line, then continues upward. I’ve already entered a long position, and I’m watching to see if it can hold steady between 2185 and 2200. If things go smoothly, I plan to reverse and short around 2230, looking for an exit opportunity. #ETH this wave is interesting; the technical setup still looks quite clear.

Recently, I came across a pretty interesting story. China's cryptocurrency mining hardware manufacturer Canaan Creative received a delisting warning from NASDAQ. The stock has been trading below $1 for 30 consecutive trading days and is now around $0.78.
Honestly, the company's situation is a bit sad. They are a Chinese company listed in the U.S. since 2019, mainly engaged in the research, development, and sales of Bitcoin mining machines, and they also operate their own mining business. Last year was particularly tough because many miners shifted to AI computing, leading to a significant drop

Just saw that D.A. Davidson released the latest research report on Caterpillar, raising the target price from $569 directly to $650, which is a pretty significant increase. However, they maintained a neutral rating, which is interesting and suggests that analysts remain cautious about the future trend. It seems to be based on some fundamental improvements, but the overall outlook is not that optimistic yet. Friends who are interested in construction machinery can keep an eye on this signal. Although the target price has been raised to $650, the neutral rating indicates there may still be other

Recently, I’ve been studying the PR strategies of European crypto projects and realized that this market is much more complex than I initially thought.
Europe is not a unified market, which is a point many teams overlook. MiCA, licensing rules in different countries, KYC/AML requirements, along with advertising restrictions, mean that each country’s attitude varies. Additionally, the language ecosystem, media environment, and retail awareness differ greatly; effective strategies in Germany may completely fail in France.
I’ve noticed significant differences between Eastern and Western Europe. A
