Recently, I’ve been researching Taiwan’s cryptocurrency taxation regulations and found that many people are still a bit unclear about withdrawing funds and reporting taxes. So, I’ve organized the current situation.
Honestly, Taiwan’s approach to taxing cryptocurrencies is still in the exploratory stage. According to the latest statement from the Ministry of Finance last year, profits from cryptocurrency trading are classified as “property transaction income,” which needs to be included in income tax declarations. But there’s a key point often overlooked: the focus of taxation isn’t on where yo

Recently, I’ve been researching how to more accurately evaluate crypto projects and discovered that many people actually confuse a key concept — fully diluted valuation, or FDV.
Simply put, FDV is the total market cap calculated by assuming all tokens (including those not yet issued) are in circulation at the current price. It may sound a bit abstract, but understanding it is really important for investment decisions.
Let’s look at an example. Take Bitcoin. Recent data shows BTC is around $70k, with a total supply of about 19.98 million coins. Using the FDV calculation — token price times tota

Recently, I heard a pretty shocking case in the community. A friend was sentenced to 3 years for buying and selling USDT, with the charge of disguising and concealing criminal proceeds. Honestly, this story scared many people because most are unaware that they might be crossing legal boundaries.
I looked into it carefully and found that the legal pitfalls related to U coin scams are more numerous than expected. Let me start with my friend's situation: he used a bank card for OTC transactions, with a transaction volume of 6.8 million, but was sentenced because the buyer was involved with a mone

Recently, some friends asked about the common M-top pattern in candlestick charts. I think this classic pattern is definitely worth a good discussion.
The so-called M-top pattern, also known as a double top, looks like the letter "M," formed by two similar high points. I've seen quite a few such movements in live trading, and each occurrence is a significant warning sign.
Let me first explain how the M-top pattern forms. During an upward trend, the price surges to a certain high, with volume noticeably increasing, then begins to turn downward. After falling to a certain level, the funds start

Recently, a friend asked about the fee structure of perpetual contracts, so I’ll give a brief overview. The main costs are trading fees and funding rates.
First, let’s talk about the trading fees. Anyone who has traded contracts knows that the fee rates for placing orders and taking orders are different. Maker orders (also called limit orders) have a fee of 0.02%, while taker orders (market orders) are 0.05%. It may not seem like a big difference, but over time, this gap can add up.
How is it calculated? It’s quite simple: the trading fee equals the position value multiplied by the fee rate. F

Recently, I’ve noticed that many traders share a common dilemma when adjusting MACD parameters: they don’t know which set of numbers to use. In fact, this issue reflects the eternal challenge of MACD parameter optimization. It sounds simple, but finding the right settings that suit you isn’t that easy.
Let’s start with the basics. The standard MACD (12-26-9) is well-known: the fast line uses EMA(12) to capture short-term momentum, the slow line uses EMA(26) to observe long-term trends, and the signal line is EMA(9). This set of parameters is widely used because of its stability and because mos

Recently, I've been observing a pretty interesting phenomenon. BlackRock's tokenized fund, BUIDL, has reached a market cap of $500 million in just 8 months, ranking second in the RWA track. More importantly, it is quietly reshaping the entire DeFi ecosystem.
First, let's talk about what BUIDL is. It's not complicated; simply put, BlackRock has brought traditional financial assets onto the blockchain. The fund mainly invests in U.S. short-term government bonds and repurchase agreements, with an annual yield stable between 2% and 4%. Each BUIDL token is pegged to $1. Currently, the APY is 4.50%,

Recently, while studying technical analysis, I was reminded of the wedge pattern. It seems that many people’s understanding of it still stays at a superficial level. In fact, the wedge pattern is quite useful in actual trading, especially when you want to catch the bottom or exit at the top.
Basically, there are two types of wedge patterns: an ascending wedge and a descending wedge. The ascending wedge looks a bit like a funnel. During an uptrend, the price makes higher highs and higher lows, but the upward momentum slows down gradually, and the two trendlines converge. It appears to be rising

Recently, I’ve been studying the development history of Solana, which helped me truly understand why this blockchain can stand out in a highly competitive market. The key figure behind it is Anatoly Yakovenko.
This guy’s background is quite interesting. Early in his career, he worked as an engineer at Qualcomm in Silicon Valley, specializing in application engineering and hardware optimization. His most well-known project was designing high-performance DSP software for Google Tango, which was the first smartphone supporting augmented reality features. In simple terms, Anatoly Yakovenko was wor

Recently, I’ve been studying an interesting phenomenon: 90% of people in the crypto space are actually trading blindly, with no idea what they’re doing. Instead of calling it trading, it’s more like gambling.
It took me years to realize one thing—traders who truly make money all have a complete plan. They don’t enter trades randomly, just like a sniper doesn’t shoot blindly. Before each move, they know their target, when to enter, and when to exit.
What’s the core of this plan? It’s finding the market’s truly important levels—I call them “key levels.” These aren’t just random prices where the

Want to quickly judge the rise and fall of cryptocurrencies? Actually, there are many tips on the 15-minute candlestick chart. I’d like to share my experience from these years of exploration with everyone.
First, learn how to read charts. I usually use TradingView, set the time frame to 15 minutes, and the most important thing is to clearly identify the current trend. An uptrend means higher highs and higher lows; a downtrend means lower highs and lower lows; if the price is oscillating within a range, that’s sideways movement. These basic judgments are crucial for predicting short-term crypto

Recently, I’ve been thinking about a question: how great would it be if we could know in advance how a trade will end? Although true risk-free profit doesn’t exist in reality, arbitrage trading essentially aims to get as close to that ideal as possible.
Simply put, arbitrage is making money from price differences of the same asset across different markets. For example, if Bitcoin is cheaper on one platform and more expensive on another, you buy low and sell high. It sounds simple, but in practice, the differences can be huge. These opportunities are often fleeting, disappearing within seconds,

Recently, I’ve noticed that many traders only have a superficial understanding of the RSI indicator. Today, let’s talk about how to properly use this tool.
The RSI indicator is essentially a measure of the strength of upward and downward momentum over a certain period, expressed on a scale from 0 to 100. In simple terms, if the market’s upward momentum is dominant, the value rises; if not, it falls. Many people only know about overbought and oversold conditions, but the RSI’s applications go far beyond that.
Regarding overbought and oversold, the most common understanding is that RSI > 70 indi

Recently, I’ve been organizing notes on stock technical analysis and found that many beginners still have a shallow understanding of candlestick charts. In fact, back in 1990 when the Chinese stock market opened, candlestick charts were already in use. To be honest, over the years, research on candlestick charts mainly relies on the Japanese theory. Most people have only learned fragmented knowledge such as single and double candlesticks, and a truly systematic pattern analysis is not yet complete.
I must admit that indicators and candlestick charts are indeed essential tools for stock trading

Recently came across a rather cautionary case involving Andrew Tate and the crypto market. This guy has a significant influence in the fan community, but reportedly he used this to orchestrate a large-scale pump and dump, causing followers to lose millions.
Here's what happened. A few weeks ago, Tate held a live stream claiming he would operate various meme coins in real-time, saying everyone could follow him to make money. Sounds tempting, right? But in reality, his hidden agenda was not to help the community, but to profit himself.
He targeted low-market-cap tokens with low liquidity, which

Recently, I saw someone ask an interesting question about a candlestick pattern: what does it mean when a doji appears at a high level along with increased volume? Let me just say, this signal is very dangerous; the main force is setting a trap.
First, let me share my observation. When a doji appears at a high level, it indicates that the price has already risen quite a bit and is not low anymore. At the same time, a surge in volume shows that both buyers and sellers are fiercely competing, and market activity is very high. But what’s the key point? The opening and closing prices are almost un

Listen to me, I recently discovered a new type of rug pull scheme that everyone must be cautious of ⚠️. This isn't the traditional meme coin scam, but a carefully disguised legitimate project.
Here's how the scheme works: the project conducts a presale before listing, which seems perfectly normal, but there's a hidden trick. Community members buy tokens expecting to profit when it gets listed on exchanges, but what happens? The distribution isn't actually completed, or they have to wait until after listing to claim it, while the founders and team have already dumped all their tokens at high pr

I recently read a report on the ranking of global investment masters and realized how much my understanding of investing still falls short. The stories of these people are truly worth studying carefully for anyone who wants to make money in the stock market.
First, let's talk about Warren Buffett. This guy has only lost money in one year over 51 years; the other 50 years have all been positive growth. How does he do it? The secret is actually simple—avoiding "compound negative returns." Many people don't understand this concept: a 30% decline requires a 43% increase to break even, a 50% declin

I've recently observed an interesting market phenomenon. As geopolitical tensions escalate, the flow of safe-haven assets is undergoing a noticeable shift. Trading volume of gold on the black market has surged, reflecting a reassessment of risk assets in the market.
The scope of the war has expanded to over a dozen countries, with advanced weapon systems like hypersonic missiles appearing frequently. The overall situation is far more complex than expected. In this context, the appeal of traditional safe-haven assets has clearly increased. The spike in black market gold prices, to some extent,
