I recently noticed an interesting phenomenon: Bitcoin surged to around $74,000 in a short period and was immediately hammered down, with many people rushing to cash out profits. This actually reflects a common psychological trap — the belief that once it reaches a certain round number, it’s time to sell.
Looking at the latest data, BTC is now hovering around 74.22K, down 0.18% in 24 hours. This rapid rise followed by a quick pullback is essentially a game between retail investors and institutions. Retail investors see the round number as a signal to lock in gains, but often this is actually th

I recently came across an interesting trend in financial innovation. A major cryptocurrency exchange has partnered with a traditional asset management giant like Franklin Templeton. The collaboration involves using tokenized money market funds as over-the-counter collateral. This combination is quite intriguing—on one side, a leading player in the crypto world, and on the other, an established Wall Street asset manager.
Speaking of which, Franklin Templeton manages a substantial amount of assets in traditional finance. Their move into the tokenized asset space indeed reflects a shift in attitu

Recently, I saw a disclosure statement from CoinDesk, an established crypto media outlet, and it made me think of some interesting things. They clearly stated their editorial policies and principles of independence, which are actually quite important within the industry. As an award-winning news organization, they have strict requirements for their journalists, including ensuring the integrity and impartiality of their reporting.
Interestingly, CoinDesk is owned by Bullish, which itself invests in digital asset companies. This means that CoinDesk’s employees, including journalists, may receive

Recently, I came across a pretty interesting cryptocurrency news topic—former Mt. Gox CEO Mark Karpelès proposed a bold idea on GitHub: to recover the stolen Bitcoin that has been locked for 12 years through a hard fork.
Simply put, that's the gist. Mt. Gox has been bankrupt for over a decade, but nearly 80k BTC (worth $5.2 billion at the time) still sit in a cold wallet, untouched. Karpelès believes this issue can't just be left alone, after all, these coins have clear ownership, unlike those stolen and lost in mixers.
His solution sounds a bit crazy: changing Bitcoin's consensus rules so tha

Recently, many beginners have been stuck by KYC when registering on exchanges, and actually, this question is asked quite often—what does KYC mean? Why does it have to be so complicated? Today, I’ll clarify this matter for everyone.
Simply put, KYC is the concept of "Know Your Customer," used by almost all legitimate exchanges and banks. It sounds like an invasion of privacy, but in reality, it’s necessary. Why? Because without this layer of verification, exchanges become hotbeds for money laundering and scams, which can seriously harm the entire market.
I’ve noticed many people don’t understa

Recently, an analyst mentioned that the recent surge in Bitcoin was mainly driven by short sellers covering their positions, rather than new funds entering the market. It seems that the market's rhythm of ups and downs has caused many traders to readjust their trading plans. Based on current market data, BTC has actually decreased by about 1.35% within 24 hours, with the price at around 71.7K. This suggests that the sustainability of the previous rebound may not be that strong, and we should remain cautious of subsequent volatility. However, from the perspective of short covering, it at least

Recently, I noticed an interesting phenomenon: Bitcoin didn't drop significantly under the pressure of Trump's new tariff policies, but instead stabilized around $71,600. This somewhat has a cipher-like implication—seems to suggest that the market's immunity to these news is getting stronger.
Even more interesting is that altcoins are leading the rebound; although the gains are modest, the direction is very clear. Bitcoin has fallen 1.63% in 24 hours, but the market's resilience is indeed improving. This cipher-like phenomenon is meaningful and may indicate that investors are beginning to diff

Recently, I noticed an interesting market phenomenon: the Japanese stock market has hit a record high of over 56,000 points, and this rally seems to be driving global asset prices higher as well. Bitcoin is also rising, currently fluctuating around $73,000, and gold is accelerating in its ascent, with safe-haven assets like Japanese gold moving in tandem.
It appears that when traditional financial market sentiment improves, crypto assets can also benefit. As a major global economy, Japan's stock market reaching new highs often signals a broader increase in risk appetite. In this rally, both Ja

Recently, I noticed an interesting phenomenon. Circle’s stock price has risen by over 20% again this week, and the logic behind it is actually worth thinking through.
The trigger was the sudden escalation of the Middle East situation. Airstrikes by Israel and the U.S. against Iran directly pushed up oil prices, with WTI crude oil rising by 7 to 8 percentage points in just a few days. This may look like a geopolitical event, but the knock-on effects on financial markets run very deep.
Analysts at Mizuho Bank in Japan picked up this logic: higher oil prices will reignite inflationary pressure, w

Recently, geopolitical tensions have eased significantly, and market sentiment has improved accordingly. I’ve noticed that the liquidity of stablecoins is expanding noticeably, which is usually a signal that funds are preparing to enter the market. Bitcoin’s price has also rebounded accordingly, currently hovering around $72k, with a 24-hour increase of over 1%.
The logic behind this rebound is actually quite clear. Once geopolitical uncertainties diminish, risk assets tend to recover. The expansion of the stablecoin market indicates that institutions and large investors are actively positioni

I just came across a pretty serious issue: blockchain investigator ZachXBT revealed that an internal employee at Axiom Exchange is suspected of abusing their privileges. Specifically, this high-level staff member used internal tools to illegally access sensitive user data, including wallet addresses, and then shared this information with a small team to track the trading activities of crypto KOLs.
According to ZachXBT's investigation, this guy even boasted in recordings that he could track any Axiom user’s information through referral codes, wallet addresses, or UIDs. Even more outrageous, the

I recently noticed that Bitcoin's price has been steadily above $70k. Currently, the latest data shows $72,890, but whether this level can hold seems to depend on the international situation.
In the past couple of days, there's been an interesting phenomenon: Bitcoin's short-term trend appears to be increasingly linked to geopolitical factors. Negotiations between Iran and the United States have surprisingly become an important variable influencing Bitcoin's price. As the market digests this information, emotional fluctuations have become more sensitive.
Honestly, many people may not realize t

Recently checked the market, and it's quite interesting. Bitcoin recently tested around $74,000 multiple times, and this week finally stabilized, with the latest price around $72,680, nearly a 9% weekly increase. But what attracts me more is the performance of altcoins, with high-risk cryptocurrencies like Ethereum and Solana surging more aggressively. ETH's weekly gain is close to 9%, SOL has risen nearly 5%, and Dogecoin has increased almost 2%, indicating that funds are rotating into higher-risk assets.
The underlying reason seems to be a easing of macroeconomic conditions. Oil prices have

Recently, the price of Middle Eastern oil has broken through the $100 per barrel mark again, and this signal is actually worth paying attention to. Many people may not realize that there is a subtle connection between oil price fluctuations and the cryptocurrency market.
From a macro perspective, rising oil prices usually indicate increased global inflationary pressure. When oil prices continue to rise, central banks face greater policy pressures, which can affect liquidity expectations across the entire financial market. Bitcoin, as an inflation hedge asset, will be reevaluated in this enviro

Recently, I've been paying attention to the ecosystem of decentralized trading platforms and noticed an interesting phenomenon—more and more people are using exchanges that don't require identity verification.
In simple terms, these are platforms where you can directly trade cryptocurrencies without submitting ID or address proof. Uniswap and PancakeSwap are typical examples. Uniswap was particularly large at the time, reaching 12 million monthly active users in August 2024, accounting for 60% of the market share. PancakeSwap, while smaller, still has nearly 2 million independent users.

Recently, I’ve found that many newcomers are still a bit confused about the concept of KYC, and they often ask what kyc means. Actually, this is very common in both traditional finance and the crypto world, but not many people truly understand its importance.
To put it simply, KYC is an abbreviation for Know Your Customer—translated as understanding your customer. Simply put, exchanges need to confirm who you are, where your money comes from, and make sure you’re not doing anything illegal with cryptocurrencies, such as money laundering or fraud.
When I first started trading crypto, I also tho

Recently, I’ve been testing overseas accounts and found that buying SIM cards directly is too troublesome, so I started researching domestic SMS verification platforms. To be honest, I’ve encountered many pitfalls before—some platforms are so slow they make you doubt life, and others simply don’t receive messages. Eventually, I found a few decent ones.
In simple terms, SMS verification platforms are services that rent virtual numbers to receive verification codes, which are quite suitable for our scenarios like temporary registration or API testing. I’ve used two international platforms, SMS-A

I just saw the latest economist survey data from the Central Bank of Brazil, and there are new changes in the forecast for the USD/BRL exchange rate. Previously, the expectation was that by the end of 2026, 1 USD would exchange for 5.42 BRL; now the forecast has been adjusted to 5.41 BRL. Although the change is small, it is indeed a positive signal.
This indicates that Brazilian economists' confidence in their local currency is gradually increasing, and the depreciation expectation of the USD against the BRL is narrowing. For those paying attention to emerging market currencies, this slight ad

I just came across an interesting market topic regarding the legal challenges to Trump's tariff policies. Previously, Trump's push for steel and aluminum import tariffs ultimately had to be decided by the Supreme Court regarding their legality.
Market traders are currently generally expecting about a 72% chance that the court will overturn these tariffs. Think about it—if that actually happens, the impact would go far beyond just a legal news story. The entire U.S. stock market, steel and aluminum producers, global trade relations, and even currency and commodity markets could all be affected.

I just realized recently that using SMS verification code platforms can really save a lot of trouble. Previously, to test SMS verification code APIs, I considered buying a new SIM card, but then I found out it's actually unnecessary—virtual number platforms can handle it all.
Basically, SMS verification code platforms are services that rent virtual phone numbers to receive verification codes. I've encountered quite a few pitfalls before—some platforms simply don't receive messages, others have delays of half a day, and it took a long time to find a few truly stable ones. Platforms like SMS-Act
