Bitcoin is often called "digital gold," but after all the talk, many people still can't figure out what it really is or why it's worth $65,000 each. Today, I'm not talking about the market or urging you to buy; instead, let's quietly break down the underlying logic and see: what it is, where does scarcity come from, and whether its value can truly stand. --- 1. Essentially, it is a "public ledger shared by the whole world" Don't let the word "coin" misinterpret you. Bitcoin's true core is a public ledger stored on thousands of computers worldwide. Who transferred how much money to whom is recorded, and every participating computer has an identical complete backup. In traditional finance, the ledger is managed by the bank—whatever the bank says you have, that's what it is. Bitcoin doesn't have this 'center'; the right to record accounts is handed over to all network nodes, and a transfer must be verified by most nodes to be truly credited. Transactions are packaged into 'blocks' by chronological order, and the blocks are connected into 'chains'—this is blockchain. Its hardest core is that no institution can secretly tamper, reissue, or freeze your assets—because to alter it, you have to simultaneously alter the vast majority of copies worldwide, which is so costly it's almost impossible. --- 2. Scarcity is not a story, but dead code The biggest weakness of fiat currency is its unlimited issuance—the more you print, the weaker the purchasing power. Bitcoin does the opposite, with a total supply fixed at 21 million from the start—no more, no less. This rule is engraved in the underlying protocol, protected by consensus across the entire network, and no one can change it. What's even more interesting is the timing of new coin releases. The new Bitcoin is a reward for "bookkeepers," and this reward is halved roughly every four years: In 2009, each block was rewarded with 50 coins, later changed to 25, 12.5, 6.25, dropped to 3.125 coins by April 2024, and is expected to be cut further to 1.5625 coins in 2028. New coin output is slowing down, with the last coin expected to be mined around 2140. So far, about 20.06 million coins (about 96%) have been mined out of the total 21 million units, with the remaining 4% gradually released over more than a century—this "fast early, slow later" design makes scarcity visible to the naked eye. --- 3. No boss, no headquarters—who really manages it? This is where beginners get confused the most—how can something without a CEO, office, or customer service keep running? It is maintained by countless mining machines and full nodes worldwide. Miners compete for bookkeeping rights through calculation; whoever first calculates a valid answer has the right to package the latest transaction into blocks and receive the system's reward of new coins. This process is called "mining." So why are these people willing to work obediently? Because the rules are designed as "honesty is the most cost-effective": to destroy or tamper with ledgers, one must control more than half of the network's computing power, which is suffocatingly costly; and even if they succeed, the token price will inevitably collapse, and their huge investment will be wasted. Therefore, everyone's profit-seeking behavior ultimately unites into a force maintaining system stability — this rule is called the "consensus mechanism." --- 4. Where does the value come from? Supply locked in + real demand The price of any asset ultimately depends on supply and demand. · Supply side: total supply is 21 million hard caps, new additions are slowing down, which is a mathematical scarcity. · Demand side: The demand over the years has truly grown— · It can be freely transferred worldwide, without banks or borders; · As long as private keys are properly managed, no government can directly freeze or confiscate them; · More and more people treat it as "digital gold" to hedge against the risk of fiat currency depreciation; · In the past two years, spot Bitcoin ETFs have been approved, allowing institutions and ordinary investors to participate like buying and selling stocks, bringing in another wave of new capital. Scarcity is the foundation, demand is the building; the combination of the two supports the current total market value of about $1.3 trillion. --- 5. Three iron rules every beginner must engrave in their minds · First, extremely volatile fluctuations. Daily fluctuations of 5%-10% are commonplace; historically, prices have been halved or even dropped by 70% from their peaks. Don't treat them as a stable financial tool. · Second, the private key is sovereignty. Whoever holds the private key truly owns the coin; If the private key is lost, stolen, or scammed, no customer service can help you recover it, which is completely different from reporting a loss at the bank. · Third, only use spare cash. It's one of the most aggressive assets of this era; the size of your position directly determines the quality of your sleep each night. Never bet on living expenses or emergency money. --- The first lesson in understanding Bitcoin isn't guessing how much it can rise, but figuring out what it is, how scarcity is realized, and what its value relies on. Once you build a solid foundation, then look at those dramatic ups and downs, you'll naturally have a scale in your heart, rather than being led by emotion. $BTC The above is purely personal learning and sharing and does not constitute any investment advice.

Last week, the non-farm payrolls unexpectedly weakened, directly pushing the market's pricing for a September Fed rate hike from hawkish bias to roughly a 50-50 chance. Tonight's CPI has therefore become the key data that can truly influence the short-term direction. I recall similar situations in past years where non-farm payrolls weakened first, followed by inflation data taking over. If the core CPI also cooled down simultaneously, gold and Bitcoin often experienced relatively smooth upward surges. However, if the core CPI remained sticky or even rebounded, the dollar and real yields on U.S. Treasuries would quickly rise, causing risk assets and gold to undergo a noticeable round of selling pressure first. This time, the environment is somewhat different. Oil prices and geopolitical risks persist, and global central banks have not stopped their gold purchasing pace. So even if the data is slightly on the hot side, the persistence and magnitude of any decline may not be as straightforward as before. Conversely, if the core CPI continues moving toward 2.5% or even lower, the market's pricing of the necessity for rate hikes will be revised down another notch. After gold digests around 4400, the upside space will open more clearly, and Bitcoin, as a liquidity-sensitive asset, will also benefit in tandem.

Singapore's Temasek plans to invest in Samsung, SK Hynix… marking its first investment in the South Korean stock market Temasek, one of Asia's largest sovereign wealth funds, is making new investments in Samsung Electronics and SK Hynix. This marks Temasek's first investment in the South Korean stock market. It is said that Temasek believes storage semiconductors are the most undervalued sector in the artificial intelligence (AI) value chain. An investment banking (IB) industry insider stated, "Temasek's investment style is to invest huge sums in market-leading industries from a long-term perspective," adding, "Samsung Hynix has risen more than 880% from last year's low, but this shows a firm belief in even higher gains."

If you hadn't been buying iPhones every year but had spent the same amount on $AAPL stocks, you might no longer be spending over a hundred thousand yuan but having millions in assets. Hearing this really hurts a little. Many people, like me, spend their whole lives as consumers, chasing new phones, new devices, and the latest features, but the ones who truly make big money are often not the first to buy products, but the ones who first understand the company's value behind the products. So now, when I look at US stocks, I'm not just looking at "I like this product," but rather at it: Does this product make users unable to leave it? Can the company continue to collect money? Are users consuming it, or are they bound by it for the long term? Apple's greatest strength isn't how stunning the iPhone is every year, but that once you use it, it's hard to leave it completely. Consumption is about spending money; equity is the part about participating in revenue sharing. $AAPL

Just now: 🇺🇸 White House official Patrick Witt stated that they are "fully committed" to passing the Cryptocurrency Clarity Act next month.

Wow, starting from September 1, Russia can officially trade BTC, ETH, and USDT, ideally bringing in $100 billion in liquidity 😲 The Russian Central Bank announced a new draft regulation today, explicitly including Bitcoin, Ethereum, and USDT in the list of crypto assets allowed for public trading on Russian exchanges. Previously, Putin signed a law legalizing cryptocurrency trading, and the new framework will take effect on September 1. Retail investors can purchase after passing a test, but each intermediary institution can buy up to 300,000 rubles per year. Qualified investors also need to pass a test but can trade other cryptocurrencies on exchanges and OTC markets with no limit on the amount. Russia also allows crypto for cross-border settlements, but using crypto directly to buy goods domestically is still prohibited.

Exclusive｜SK Hynix Dalian Expands Production by 50%, Restarting NAND Factory After Four Years of Suspension After four years of suspension, SK Hynix's NAND flash expansion plan in China has finally resumed. The second factory (Fab 2) in Dalian is accelerating construction, and after commissioning, the local total capacity will increase by about 50%. According to semiconductor industry insiders on August 11, SK Hynix's NAND subsidiary Solidigm resumed investment in Dalian Fab 2 in the first half of this year and restarted construction. Production equipment is expected to be moved in as early as November this year, with the goal of establishing a mass production system by the first half of next year and officially starting NAND flash manufacturing. The new production line is designed for a monthly capacity of about 50,000 wafers. Combined with the existing Dalian Fab 1's monthly capacity of 100,000 wafers, SK Hynix's total monthly capacity in China will increase to 150,000 wafers, a 50% increase. Construction of this factory began in May 2021—at that time, SK Hynix had just completed the acquisition of Intel's NAND business and launched Solidigm, taking over Dalian Fab 1 and the surrounding land. However, the project was long suspended after only completing the structural framework due to the storage market downturn and U.S. export controls on semiconductor equipment to China. The restart is driven by the explosion in enterprise SSD demand due to AI data center expansion, with NAND prices soaring to nearly 10 times those of a year ago, reversing the market environment. In terms of capacity layout, SK Hynix adopts a "dual-track strategy": the Dalian factory focuses on mature processes, utilizing Intel's legacy floating gate architecture to mainly expand mass production of 100-layer NAND; while advanced high-layer products above 300 layers are concentrated at the M17 factory in Cheongju, South Korea. SK Hynix previously announced an investment of 19.1 trillion KRW in M17, planning to activate the first cleanroom for next-generation NAND production by the end of 2028. An insider added: "Dalian Fab 2 will use the same equipment configuration as Fab 1, with a monthly wafer input expected between 40,000 and 60,000." With the new factory coming online, SK Hynix's mature capacity in China will be further consolidated, while advanced processes remain domestic, forming a clear gradient division of labor.
