Bitcoin is often called "digital gold," but after all the talk, many people still can't clearly explain what it really is or why it can be worth $65,000 each. Today, we won't discuss market trends or persuade you to buy or sell; we'll quietly break down the underlying logic: what it is, where its scarcity comes from, and whether its value really holds up. --- 1. Essentially, it is a "public ledger shared worldwide" Don't be misled by the word "coin." The true core of Bitcoin is a public ledger stored on thousands of computers around the world. Every transaction—who sent how much to whom—is recorded there, and every participating computer has an identical complete copy. In traditional finance, ledgers are controlled by banks—if the bank says you have a certain amount, that's what you have. Bitcoin has no such "center." The bookkeeping rights are given to nodes across the network; a transaction is only officially recorded after being verified by the majority of nodes. Transactions are packaged by time into "blocks," which are linked sequentially into a "chain"—this is the blockchain. Its most hardcore feature is that no institution can secretly alter, inflate, or freeze your assets—because to do so, one would have to simultaneously alter the vast majority of copies worldwide, which is prohibitively costly. --- 2. Scarcity is not a story; it is hard-coded The biggest weakness of fiat currency is that it can be issued without limit; the more printed, the weaker the purchasing power. Bitcoin goes the opposite way: its total supply is fixed at 21 million from the start, no more, no less. This rule is embedded in the underlying protocol and protected by network consensus; no one can change it. Even more interesting is the release schedule of new coins. New bitcoins are rewards for "bookkeepers" (miners), and this reward halves approximately every four years: In 2009, each block rewarded 50 bitcoins, then 25, 12.5, 6.25, and by April 2024 it has dropped to 3.125. It is expected to halve again to 1.5625 in 2028. The production of new coins slows down over time, with the last bitcoin expected to be mined around 2140. So far, about 20.06 million (about 96%) of the 21 million total have been mined, with the remaining 4% to be released slowly over more than a century—this "fast early, slow later" design makes scarcity visibly tangible. --- 3. No boss, no headquarters—who manages it? This is where beginners often get confused—how does something with no CEO, no office, and no customer service keep running? It is maintained by countless mining machines and full nodes worldwide. Miners compete with computing power for bookkeeping rights; whoever first finds a valid solution can package the latest transactions into a block and receive the system reward of new coins—this process is called "mining." Why do these people willingly work? Because the rules are designed so that "honesty pays best": to attack or alter the ledger, one must control over half the network's computing power, which is prohibitively expensive; even if achieved, the coin price would collapse, wiping out the huge investment. So, everyone's profit-seeking behavior ultimately aligns to maintain system stability—this set of rules is called the "consensus mechanism." --- 4. Where does the value come from? Supply locked + real demand The price of any asset ultimately depends on supply and demand. · Supply side: a hard cap of 21 million, with new issuance slowing down—this is scarcity at the mathematical level. · Demand side: demand has genuinely grown over the years— · It can be transferred globally without banks or border restrictions; · As long as private keys are kept safe, no government can directly freeze or confiscate it; · More and more people treat it as "digital gold" to hedge against fiat currency depreciation risk; · In recent years, spot Bitcoin ETFs have been approved, allowing institutions and ordinary investors to participate like trading stocks, bringing in new capital. Scarcity is the foundation, demand is the building; together they support the current total market value of about $1.3 trillion. --- 5. Three iron rules every beginner must engrave in their mind · First, extreme volatility. Daily swings of 5%-10% are common; historically, it has halved from peaks or dropped by 70%, so never treat it as a stable investment tool. · Second, private key equals sovereignty. Whoever controls the private key truly owns the coins; if the private key is lost, stolen, or scammed, no customer service can help recover it—this is completely different from bank loss reporting. · Third, only use spare money. It is one of the most aggressive assets of this era; your position size directly affects your sleep quality every night, so never bet your living expenses or emergency funds. --- Understanding Bitcoin: the first lesson is not guessing how high it can go, but first clarifying what it is, how scarcity is realized, and what its value depends on. Once you solidify this foundation, when you see news of wild price swings, you will have a scale in your heart instead of being led by emotions. $BTC The above is purely personal learning sharing and does not constitute any investment advice.

After financial freedom, what do you want to do with $ETH?

AI infrastructure construction is becoming a power struggle, with this group now controlling about 32 GW of planned capacity that can be repurposed for higher-value computing resources: • $IREN ~5.8 GW • $CIFR ~4.0 GW • $HUT ~3.8 GW • $WULF ~3.6 GW • $MARA ~2.8 GW • $CORZ ~2.6 GW • $RIOT ~2.0 GW • $CLSK ~1.8 GW • $GLXY ~1.7 GW • $BITF ~0.8 GW These companies already control one of the scarcest inputs in the AI economy, so even if part of the 32 GW is converted to full-stack computing, the revenue opportunity per MW could expand by about 6 times.

$NVDA earnings report next Wednesday, will it "die in the light" again this time? NVDA earnings: it's not about whether it beats expectations, but by how much. Historical pattern — running ahead before earnings, often falling after earnings. This time focus on Q3 guidance, Rubin progress, and major companies' CapEx. It's not that the performance is bad, but the market expectations have already hit the ceiling. If Wall Street wants it to fall, it will fall. ---

Citadel Securities stated 10 days ago: Systematic buyers are preparing to buy stocks in large quantities again after experiencing massive liquidations... Rebound potential is building up, and the next significant mechanical capital flow might be re-leveraging rather than deleveraging. $SNDK

Supporting $AAOI is becoming increasingly difficult, as they keep selling off $50 million or $60 million worth of ATM everywhere. At some point, the operational outlook might be positive. But the equity structure/financing is becoming increasingly unfriendly to shareholders. Really, really hate ATM and constant capital raises, even if they are increasing capacity.

Ken Griffin's Citadel has already stripped over 80% of the total risk taken on by Leopold Aschenbrunner's Situational Awareness portfolio. Griffin spoke about the exit: "These include the largest intraday block trades on 10 different instruments this year. In the US, we quickly exited most of the Vega risk, saving a significant amount of capital in the process. Among the remaining G10 positions, only five have a fair market value exceeding $250 million..."

SPCX has officially entered a downward unlocking channel, initially targeting the 115-125 range. Fundamentally, the successful recovery of Zhuque-3 has further weakened SPCX's technical scarcity premium. The downward rebound will likely wait until this batch of selling pressure is fully absorbed and Starship 14's launch brings more key positive catalysts. However, if Starship 14 cannot launch by the end of August, and another batch unlocks on September 9, the stock price decline may continue into mid to late September. Let's wait and see. Who knows what capital maneuvers Elon Musk might pull to support the stock price in the meantime? It's just a cycle of falling too much, then rising too much, then falling again—there's no one-sided market where only one party profits.

30 years later, you lie on your sickbed. Your little granddaughter leans on the bedside, innocently asking: "Grandpa, I heard that in your time, $BTC was only worth tens of thousands of dollars each. Why didn’t you buy it?" You remain silent for a long time. The sunset shines through the window, and the hospital room is so quiet that only the sound of the heart monitor remains. You tremble as you open your wallet, inside still lying the 372U left after your short position blew up back then. You sigh: "Child, on August 19, 2026, I thought it was just a normal rebound." Your little granddaughter is stunned: "So you didn’t buy?" You close your eyes, tears streaming down your face: "Not only did I not buy." "I even added to my short position."

Overnight, people in the crypto circle finally remembered that they are part of the crypto circle

On August 20, as industry giants begin to accept computing power (compute) as a tradable asset, the U.S. Commodity Futures Trading Commission (CFTC) is publicly soliciting comments on computing power futures contracts. Several exchanges, including CME Group, Intercontinental Exchange, and emerging fintech company Architect Financial Technologies, have announced plans to launch related contracts upon receiving regulatory approval. These exchanges stated that establishing a computing power futures market helps end users and speculators hedge risks related to energy shortages or other issues that may affect technological progress for AI developers. CFTC Chairman Michael S. Piwowar said in a statement on Wednesday: "Without a robust computing power derivatives market, the U.S. cannot win the AI race. This solicitation is the first step in establishing clear rules for the U.S. computing power market." One of the issues the CFTC is seeking comments on is how computing power futures differ from other types of derivatives or underlying commodities currently regulated by the agency. If computing power futures are allowed to be listed on CFTC-regulated exchanges, it may require further standardization of various variables affecting computing power prices, including price indexes used for settlement reference.
