Recently, I needed to register some overseas accounts for testing and suddenly realized one card wasn't enough. Later, I found out about the virtual number platforms that allow receiving SMS verification codes, saving the trouble of buying multiple SIM cards. After trying out a few unreliable platforms, I compiled a list of trustworthy ones to share with everyone.
Basically, these verification code platforms are about renting temporary phone numbers, covering countries worldwide. After registration, you select a country code, and the verification code appears directly in the backend. Unlike re

Notice an interesting phenomenon. In recent weeks, retail investors have been actively buying Bitcoin, and the number of small wallets holding less than 0.1 BTC has hit a new high since mid-2024. But this rebound has never really had momentum; prices have repeatedly oscillated between 73K and 74K, and every time they rally higher, they get pushed back down.
According to on-chain data, the problem is here: the so-called big holders (holders of 10-10000 BTC) have been going the opposite way since last October, continuously reducing their positions. Put simply, retail investors are buying, while

Tomorrow is the quadruple witching expiration day, and it seems like both exchanges and the community have been discussing it lately. Days when multiple contracts expire simultaneously, like during quadruple witching, have historically been prone to market volatility. Everyone has probably felt Bitcoin's performance over the past couple of days.
Many people are preparing, some adjusting their positions, and others observing on-chain data and futures holdings. How much impact quadruple witching will actually have, no one can say for sure, but market participants are definitely paying close atte

I recently came across a rather interesting topic. Traditional financial heavyweight Charles Schwab has recently released recommendations on crypto-asset allocation, and their core takeaway is especially poignant—even allocating just 1% to Bitcoin or Ethereum can significantly alter the risk characteristics of your entire investment portfolio.
This is not just alarmism. Schwab’s analysis points out that the volatility of cryptocurrencies is far greater than that of traditional assets. Bitcoin’s annual volatility is over 60–80%, while U.S. stocks are typically only 15–20%, and bonds are even ju

I've been keeping a close eye on the USD/JPY currency pair lately, and it feels like the market logic has become a bit more complex. Last week, I took a look at the technicals: USD/JPY has already broken above the 158.50 level, setting fresh highs in many years. Now, the market is focused on the 159-159.50 range. From the candlestick chart, the 50-day moving average is at 156.80, and the 200-day moving average is at 153.20—both are providing support from below. The RSI is approaching 68, which is somewhat overbought, but there’s no divergence signal yet. To be honest, from a chart perspective,

Recently, I found that many beginners are still a bit unfamiliar with the concept of staking mining, so I thought I’d share my understanding. To be honest, staking mining is indeed a very interesting way to make money in the crypto world, but it’s not as magical as some articles make it out to be.
Simply put, staking mining means locking your cryptocurrency into a blockchain network to help run the network and verify transactions. In return, the network rewards you with some coins. The logic isn’t complicated; it’s like earning interest by depositing money in a bank, except here you’re deposit

Recently, many people still have some misunderstandings about perpetual contracts, especially not fully understanding how they differ from traditional futures. I'll discuss this from a trader's perspective.
Traditional futures contracts have a fatal flaw — they must be settled at expiration. For example, if you buy gold futures, at the contract's expiration, physical delivery of gold must occur according to the terms, which means incurring storage costs. Additionally, as the delivery date approaches, the difference between spot prices and futures prices can grow larger, increasing your holding

Recently, there has been a significant development in the Cardano ecosystem. The privacy-focused blockchain project Midnight is about to go live officially, and Charles Hoskinson recently revealed this news.
The core selling point of Midnight is privacy, which is indeed a differentiated direction in the current blockchain ecosystem. As regulations become stricter and users' privacy needs increase, Cardano, as an established public chain, still has interesting plans in this track.
According to the schedule, Midnight is expected to be launched around March, which is a major event for the entire

I just came across a pretty shocking case: Lin Ruixiang, the founder of the Yinxin Market, was sentenced to 30 years in prison for operating an underground drug trading platform on the dark web. Back then, the dark web marketplace he built was fairly large, until law enforcement dismantled it.
30 years—this sentence really isn’t light. When you think about it, these illegal trading markets on the dark web may look well hidden, but in the end, they still can’t escape the reach of the law. It feels like a lot of people underestimate law enforcement’s ability to track things, thinking that if you

Recently, I came across a piece of data that’s quite interesting—about the growth of the cryptocurrency market in Latin America. According to the report, the growth rate of cryptocurrency users in the Latin American region in 2025 is actually three times that of the United States. This figure really reflects a very clear trend.
It also makes sense when you think about it. Many countries in Latin America face issues like currency devaluation and financial instability, and cryptocurrencies provide local users with a new option for asset allocation. Moreover, Latin America has a high proportion o

Recently, I saw people discussing cases where certain stocks are being shorted, and it reminded me of an interesting statement CoinDesk made about its own background. This media outlet still has some influence in the crypto industry, and in 2023 it even won a journalism award for its in-depth coverage of FTX. But there’s one noteworthy point here—its parent company, Bullish, itself has an investment presence in the digital asset space, which means CoinDesk employees, including reporters, may hold related equity incentives.
In other words, when a media organization has such investment ties behi

最近发现身边不少人在讨论量化交易，我其实有点意外。这东西对散户来说门槛其实挺高的，大多数人接触到的无非就是买别人的APP、代码脚本这类东西。说实话，这里面大部分都是坑。逻辑很简单嘛，如果某个人自己做量化交易真的能稳定赚钱，甚至像他们宣传的那样永赚不赔，那他们为什么还要出来卖这些东西呢？
今天就想好好聊聊量化交易到底是个啥，散户到底能不能真正用上。
先说术语。量化交易（Quantitative Trading）听起来很高大上，其实就是用数学模型、统计分析和计算机程序来做交易决策。它吃的是大量历史和实时数据，通过算法自动找市场机会、生成信号、执行买卖。简单说就一句话，由数学模型驱动策略进行自动化交易。
你看像幻方量化这样的知名机构，梁文锋他们有出来卖量化交易工具吗？没有吧。人家对外的服务基本都是资管类的，这才是真正的量化交易公司该做的事。
量化交易的核心逻辑是什么呢？就是用数据和系统化决策去替代人的主观判断。它从海量历史数据里挖掘大概率事件和规律，建立数学模型预测市场走势，然后用历史数据反复回测验证策略有没有效，最后通过程序严格执行，避免被情绪影响。听起来确实很理想，但问题也存在，模型基于历史数据，一旦市场出现黑天鹅事件就容易失效，而且过度优化还会导致过拟合现象，历史数据好看但实盘一用就拉胯。
和传统交易比，传统交易靠经验、直觉和基本面技术分析，主观性强；量化交易完全数据化自动化，更适

Recently, I’ve noticed that many people still have some confusion about profit and loss calculations in crypto trading, especially the concept of pnl. In fact, the profit and loss logic in traditional finance is basically the same as in the crypto world, but there are some details worth understanding deeply.
Let's start with the basics. PnL is used to reflect the change in your position value over a specific period. Without a clear framework to understand your profits and losses, trading can become really chaotic. I’ve seen many traders who have been trading for over half a year but are still

Recently, I frequently need to use temporary phone numbers, such as testing verification code interfaces or registering overseas accounts. Buying new SIM cards is not cost-effective, and I later discovered the SMS verification platform, which is a lifesaver. Basically, it uses virtual SMS numbers to replace real numbers for receiving SMS verification codes, so you don't have to worry about privacy leaks and can quickly handle various testing needs.
I've experienced quite a few pitfalls myself, trying several platforms—some simply don't receive messages, others have huge delays. In the end, I s

Recently, a friend asked me about wallet security, and as we talked, the topic shifted to mnemonic phrases. I realized that many people don't truly understand why mnemonic phrases are so important; they are just told to back them up and keep them safe, and that's it. But without understanding the underlying logic, it's hard to truly appreciate their significance.
Let's start with private keys. A private key is the key to your digital assets; only by controlling the private key can you truly control those assets. The problem is, private keys are usually random 64-character hexadecimal strings,

While recently revisiting the history before Pi’s launch, I suddenly realized that this project has taken a rather unusual path—from the seed of the idea to reaching the market.
First, let’s talk about the two founders. Chengdiao Fan is a Ph.D. in Behavioral Science from Stanford, and his research focuses on human-computer interaction and social computing—simply put, how to use technology to influence human behavior. The other is Nicolas Kokkalis, a Ph.D. in Computer Science, who also teaches blockchain at Stanford. What’s interesting is that among Dr. Fan’s classmates at Stanford is an except

Recently, I’ve seen many discussions in the community about losses during a bull market. I’ve also noticed an interesting phenomenon: when prices rise, traders tend to lose the most. It sounds ironic, but it’s a common trap in the market.
A bull market should be the easiest time to make money, so why are so many people still losing? I believe the core reason is that emotions take over rationality. When a coin suddenly surges 50% or even doubles, FOMO kicks in. Many traders aren’t accumulating early and positioning themselves ahead of time; instead, they wait until the gains are already signifi
