Recently, I needed to use a virtual number to receive verification codes, and I realized that many people are still not very familiar with SMS verification platforms. Basically, it's renting a temporary phone number to receive SMS verification codes, which is especially suitable for registering overseas accounts or conducting API testing. I've encountered many pitfalls before, tried several platforms, some of which couldn't receive messages at all, others had delays of half a day, but I eventually summarized a few decent ones.
The principle of verification code platforms is actually very simpl

I just finished translating a long article about Vitalik Buterin, and I feel there are some things worth discussing.
This guy is definitely not simple. Born in a small town in Russia called Kolomna, he started playing with Excel at age 4, and by 19 he had written the Ethereum white paper. Now at 31, he's being criticized for some decisions as "stubborn" and "idealistic." Some call him "V God," while others call him "Little V," but regardless, this thin Russian teenager has indeed changed the entire blockchain world with his own efforts.
His story is actually quite interesting. Growing up in co

Recently, some friends asked me how to trade perpetual contracts, so I整理ed my understanding in hopes of helping beginners avoid detours.
Speaking of perpetual contracts, this is indeed one of the most common trading tools in the crypto world. Simply put, a perpetual contract is a way to bet on price movements without actually holding the asset. Its English name is Perpetual Futures, abbreviated as PERP, for example, Bitcoin's perpetual contract is called BTC-PERP.
Why do so many people use perpetual contracts? There are mainly a few reasons. First, it allows short selling, meaning even if you

Recently, I frequently need to register overseas accounts for testing, and each time I get stuck on phone number verification codes. Later, I found that using an SMS reception platform really saves a lot of trouble. I had fallen into a few traps before—like platforms that couldn’t receive texts and codes that only arrived after half a day—but gradually I found a few that are decent.
To put it simply, an SMS reception platform is a service that rents virtual phone numbers, covering locations around the world. You can choose either pay-per-use or a monthly plan. I mainly use it to test interface

Recently, Italian politics has become quite interesting, as the opposition has begun to challenge Meloni. Bloomberg reports that an emerging political figure is gaining prominence, aiming to shake up Meloni's position as Prime Minister.
The logic behind this movement is quite clear — some policies of the current government have caused considerable dissatisfaction, and the opposition has seized this opportunity to rally supporters. Although Meloni holds an important position in Italian politics, she is obviously facing increasing scrutiny.
Interestingly, this is not a sudden event, but a gradua

Recently, there has been an interesting phenomenon in the market: the back-and-forth in the US–Iran situation is directly influencing foreign-exchange trends. Last week, the US Dollar Index fell by 0.48%. Non-US-dollar currencies generally rebounded, with the euro up 0.34%. The logic behind this is actually worth thinking through.
First, let’s talk about the euro. Last week, EUR/USD rose by 0.34%. The main reason was that the market at one point became optimistic about the prospects for negotiations between the United States and Iran. Trump said that an agreement would very likely be reached i

Last week, the foreign exchange market was lively again. Once the news of a ceasefire between the US and Iran came out, non-US currencies all rebounded. I looked at the data, and the dollar index fell by 1.49%, the euro rose by 1.78%, and the Australian dollar even increased by 2.47%. But can this rebound last? I think it still depends on how the US-Iran situation develops.
On the euro side, it rose for five consecutive trading days mainly due to expectations of a ceasefire agreement. But the turning point came—Trump threatened to block the Strait of Hormuz, and now the market's bets on a Fede

Recently, I’ve been pondering a question: if AI can make software smarter, and encryption technology can digitize ownership, what happens when these two come together?
My answer might be surprising — it’s not just a better tool, but a completely new form of company.
You see, many people are now experimenting with AI encryption — payments, identity, reasoning training — these areas all have value. But they’ve missed a more fundamental point: the core capability of encrypted assets isn’t just payments, but enabling software-native entities to own, control, and operate assets. That’s the real bre

I just saw a pretty explosive piece of news. SpaceX recently secretly submitted an IPO application, and if things go smoothly, this round of financing could be as large as $75 billion.
So what does that mean? Based on this financing scale and valuation level, SpaceX’s corporate valuation would be close to $1.5 trillion. And for Elon Musk, the impact would be even bigger—his personal net worth could break through to around the $1 trillion mark.
To be honest, that figure is quite shocking. Musk has super companies like Tesla and SpaceX, and if SpaceX’s IPO really comes to fruition, his wealth ma

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
