為什麼購買 比特幣 (BTC)?

什麼是比特幣?——去中心化的虛擬黃金
比特幣 (Bitcoin, BTC) 由中本聰於 2008 年發佈白皮書,2009 年正式上線,是全球首個去中心化加密貨幣。比特幣允許用戶在無需銀行或政府等中介機構的情況下進行點對點電子支付。所有交易都透過區塊鏈公開記錄,每一筆轉帳都可被全網節點驗證,保障安全性與透明度。
比特幣如何運作?PoW 共識與區塊鏈技術
比特幣基於工作量證明 (Proof of Work, PoW) 共識機制運行。當 Alice 想將 1 BTC 轉給 Bob 時,礦工會競爭解答複雜數學題,率先完成者獲得新增比特幣作為區塊獎勵,並將交易永久記錄在區塊鏈上。這種機制確保了網路安全,但也導致高能耗和挖礦難度逐年提升。
比特幣供應與減半機制
比特幣總量被嚴格限制在 2,100 萬枚,具備絕對稀缺性。大約每四年,比特幣會經歷一次“減半”(Halving),即礦工獎勵減半,降低新幣產出速度。這一機制強化了比特幣抗通脹屬性,也是其價格長期上漲的重要動力。截至 2024 年底,已開採超過 1,970 萬枚比特幣。
價格歷史與市場影響
比特幣自誕生初期幾乎毫無價值,到 2017 年突破 2 萬美元並於 2021 年創下 6 萬多美元新高。歷史上比特幣經歷多次劇烈波動,例如“比特幣披薩日”標誌著首次商業應用(1 萬 BTC 換兩塊披薩)。雖然曾被質疑為泡沫或騙局,但主流媒體和機構投資者陸續入場,推動市值突破 1 萬億美元。
投資比特幣的理由與風險
抗通脹與儲值功能:固定供應與減半機制使比特幣成為虛擬黃金,被視為避險資產。 高流動性:BTC 在全球各大交易所均可自由買賣,便於資產配置。 去中心化與匿名性:不受單一國家或機構控制,用戶擁有資產自主權。 技術與政策風險:價格波動劇烈,監管政策尚未明朗,挖礦能耗引發環保爭議,且支付應用仍有限。
懷疑者觀點與替代思考
儘管比特幣具有革命性意義,但其作為支付工具效率低、波動大、法規風險高。部分專家認為比特幣更像是一種高風險投機品,而非穩定的價值儲存工具。投資者應理性評估自身風險承受能力。

$BTC | THE NEXT MOVE IS LOADING
Bitcoin briefly dipped below the current range, but buyers quickly stepped in and reclaimed the mid-range support/resistance zone.
Saturday = Low Volatility
With it being Saturday, I’m not expecting a major expansion today. BTC is more likely to continue ranging within this tight lower-timeframe structure while liquidity builds for the next directional move.
Key Retest Zone: $85.7K
The imbalance around $85,700 remains the level I’m watching most closely.
If BTC reaches this area and faces a strong rejection, I’ll be looking for another move toward the downside.
However, the broader setup remains interesting.
What I’m Watching Next Week
My expectation is that BTC could establish a new local high next week, with a larger local top potentially developing over the following couple of weeks.
For now, there’s no reason to force a trade.
Bitcoin is simply consolidating and preparing for its next move.
Stay patient. Let the price come to you.
I’ll keep you updated when the setup becomes clear.

Core PCE "Cooled" to 3.0% Because the Ruler Changed, Not Because Prices Did: A Deep Dive Into the Print, the GDP Revision and What Markets Did Next
The market walked into Wednesday expecting core PCE at +0.3% on the month and 3.3% on the year, with headline at 3.7%. What printed was 0.2% and 3.0%, with headline at 3.4%. That looks like a clean miss, and the first reaction treated it that way. But the detail that matters sits in the revisions. The annual update changed how software, legal services and portfolio fees are measured, and July core was restated from 3.3% to 3.0% while July headline went from 3.7% to 3.4%. On the new series, core was 3.0% in July and 3.0% in August. The 3.3% everyone was comparing against belonged to a ruler that no longer exists, and the annual rate did not actually fall.
Look at the monthly numbers on the same basis and the story flips slightly. Core rose 0.2% against a revised 0.1% in July, and headline rose 0.3% against 0.1%. Momentum picked up, and energy did most of the work: gasoline rose 4.4%, energy overall rose 2.3%, and transportation services rose 1.4%. That matters because Brent finished September about 14% higher and is sitting near 106, so that pass-through has not been fully booked yet. The September PCE report lands on October 29, a day after the Fed decides on October 28. The committee will have to make its call without seeing the next inflation print.
The spending side is where I think the report is most revealing. Nominal spending jumped 0.9% and real spending rose 0.6%, the strongest since March 2025. But real disposable income was flat at 0.0%, and the saving rate dropped from 4.6% to 4.1%, the lowest since late 2022. Part of the goods surge, $114.1B against $76.7B for services, is payback for a July in which goods spending fell $38.4B. Households spent from savings, not from income, while consumer confidence sat near a 12-and-a-half year low in September. Strong spending, weak confidence and flat real income is not a durable mix, and a central bank hiking into it is leaning on consumers who are already running down their buffers.
The final Q2 GDP tells a similar story. Growth was revised up to 2.2% from 1.5%, with Q1 now at 2.5%. Final sales to private domestic purchasers grew 4.6%, up from 4.2%, and income-side growth was revised to 2.6% from 2.2%, helped by AI-related equipment spending running at double-digit rates. At the same time the price side was revised down: Q2 core PCE to 3.3% annualized from 3.6%, and headline PCE to 5.0% from 5.3%. So the final read is stronger growth and slightly less inflation, but the growth is driven by AI capex and savings, not wages. That is neither stagflation nor a clean goldilocks, and it is exactly why the Fed cannot simply declare victory.
Here is what higher for longer means now. After the September 16 hike, the first since 2023, the debate moved from when cuts return to how many hikes are left. October hike odds fell from about 70% to about 25% in a single week, helped by Williams and Jefferson saying more time is needed. After Friday's 29K payrolls, hold odds for October 27 to 28 rose to about 80%, but a December hike is still around 86% priced. My read is that the market is pricing two things at once. Wages at 3.0% year over year and a three-month payroll average near 50K give the Fed room to wait, while energy keeps inflation stuck near 3%, and raising rates does not reopen the Strait of Hormuz. I lean toward 86% for December being too aggressive.
Cross-asset, the 72 hours since the print have been telling. The 10-year touched 5.344% on Thursday, the highest since 2002, and the 30-year about 5.69% intraday, then both eased. The S&P 500 closed Friday at 7,722.72, up 0.7%, above the 7,718.45 level that capped the hourly chart all week, with the Nasdaq up about 1.2% and Nvidia at a record. Gold fell about 6% in September, from 4,489 to 4,110, and is heading for a second weekly decline, with XAUT near 4,188 on Friday morning and still under its hourly 200 average at 4,221.7. Bitcoin jumped above 85,500 after the PCE print, fell below 83,500 within about ninety minutes, spiked to 87,250 after payrolls and now sits near 84,600. ETH has been rejected three times between 2,743 and 2,748. Equities are taking the softer data as a green light, while gold and crypto are still waiting for real yields to give them relief.
My plan by asset. On US500 I am bullish while closes hold above 7,718.45, with invalidation on a close back under 7,675.94 and a first target near 7,770. On XAUT I stay neutral below 4,221.7. A close above that level targets 4,280, while a break under 4,157.4 puts the 4,110 September low back in play. On BTC the floor is 84,068 and the ceiling is 87,250 to 87,400, with invalidation on a daily close under 82,281. On ETH I am constructive while 2,676.07 holds, and only a daily close above 2,743 opens 2,787 to 2,805.
If payrolls are adding 29K a month and wages are at 3.0%, does the Fed still hike in December because oil keeps inflation near 3%, or does a cooling labor market finally buy it time?
