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。

$77,600 $BTC —did you get shaken out of the ride?
First, look at the surface: rate-hike odds jumped to 57%, with longs taking a bloodbath.
On Friday, Jackson Hole—newly appointed Fed chair Kevin Warsh delivered his first remarks, leaning hawkish. PCE inflation is 3.7%, the 2% target is “firm, fixed,” and the odds of a September rate hike surged from 35% straight to 57%. BTC was dumped from 803,000 down to a low of 769,000—down a full 3%, wiping out $480 million of long positions.
Friday’s low at 76,800 held. Today there’s low-volume consolidation around 77,700. The RSI has slid down from overbought and is repairing—waiting for direction.
First thing: the Fed spoke tough, but institutions are voting with real money.
Warsh’s speech translated into plain English: “Inflation is still high—don’t expect me to cut rates soon. Even the possibility of more hikes.” The market reacted immediately—U.S. Treasury yields spiked, the dollar strengthened, and risk assets all dropped to their knees.
But U.S. spot BTC ETF net inflows exceeded $3 billion, with 8–9 straight trading days of inflows. On Friday alone it flipped to a net outflow of $200 million, but the institutional buying throughout August has been real.
Second thing: the real problem is the 81,000 level.
The upper edge of the downtrend channel from the historical high of 126,000 lines up perfectly with 81,000. The 50-week moving average is also sitting at 81,000. This August rally from 62,000 to 81,500 hit 81,000 three times—each time it was smashed back.
The 81,000–86,000 zone is a super supply area—long holding costs, options Gamma, and previously trapped positions all piled together. To get through it, you need strong volume plus macro support. Missing either one doesn’t work.
Third thing: you need to see the cracks in the fundamentals clearly.
Institutional channel is the hard support: total ETF size is about $100B, IBIT continues to pull in funds, with $3B inflow in August. In mid-to-late August there will still be a large round of short-squeeze pressure, which is resonating with ETF buying.
But there are cracks too:
Relative to the 126,000 all-time high, you’re still down 38%
Since 2026, the overall ETF is still net outflow—August only recovers half
High rates aren’t over; the cost of capital isn’t friendly to leverage
Near 80,000, a lot of trapped positions have just broken even—sell pressure could flood in at any time
Trading strategy
Bullish bias:
Pull back to 76,800–77,200 for a small-position long. Stop-loss at 76,400 or 75,500. Targets 78,300–78,800; second target 79,800–80,200. Only consider adding size if price holds above 80,000, aiming for 81,000.
Bearish bias:
Only consider shorting if there is a valid breakdown below 76,800 (4-hour close confirmation + volume). Target 75,500 down to 73,000.
Breakout strategy:
If the daily close is above 81,100 and the subsequent retest holds without breaking, that’s the real trend-change signal

BTC at $77,700—did you get shaken out?
Look beyond the surface: Rate hike odds surged to 57%, and longs were slaughtered.
At Friday’s Jackson Hole meeting, newly appointed Fed Chair Kevin Warsh’s first speech was hawkish—PCE inflation is at 3.7%, with the 2% target “firm, fixed”; September rate hike odds jumped directly from 35% to 57%. BTC crashed from $80.3k to a low of $76.9k, dropping a full 3%, while $480 million in longs were liquidated.
Friday’s low of $76,800 held, and today’s low-volume consolidation is hovering around $77,700, with RSI retreating from overbought levels and recovering as the market waits for direction.
First: The Fed talked tough, but institutions are voting with real money.
Translated into plain English, Warsh’s speech was: “Inflation is still high. Don’t expect me to cut rates anytime soon; I might even hike again.” The market reacted immediately—Treasury yields surged, the dollar strengthened, and risk assets collapsed.
But monthly US spot BTC ETF net inflows exceeded $3 billion, with inflows continuing for 8–9 consecutive trading days. Although Friday saw a shift to $200 million in net outflows, institutional buying throughout August was real.
Second: The $81k hurdle is the real problem.
The upper boundary of the downtrend from the $126k all-time high is right around $81k. The 50-week moving average is also at $81k. During August’s move from $62k to $81.5k, BTC challenged $81k three times and was knocked back three times.
$81k–$86k is a massive supply zone—long-term holder costs, options Gamma, and previous trapped positions are all stacked there. To break through, volume and macro support are both required; missing either one makes it futile.
Third: You need to clearly see the cracks in the fundamentals.
The institutional channel is solid support: Total ETF assets are approximately $100 billion, IBIT continues to attract funds, and August inflows reached $3 billion. There was also large-scale short squeezing in mid-to-late August, creating a resonant rally together with ETF buying.
But there are cracks too:
Compared with the $126k all-time high, BTC is still down 38%
ETF flows overall remain net negative so far in 2026; August only recovered half of the outflows
High interest rates have not ended, and funding costs remain unfavorable for leverage
Large amounts of trapped positions around $80k have just broken even, and selling pressure could surge at any time
The bulls and bears—judge for yourself
On one side:
August ETF inflows exceeded $3 billion, with institutions entering with real money
Friday’s low of $76,800 held, and buyers are still supporting the market
The 200-day moving average is at $69k, and the trend structure is recovering
US national debt has surpassed $40 trillion, and the long-term “inflation hedge” narrative is not dead
On the other side:
$81k has failed three times, with the upper boundary of the downtrend effectively capping the price
September rate hike odds surged to 57%, and the macro backdrop suddenly turned hawkish
Trapped positions around $80k are breaking even and creating selling pressure
Low-volume consolidation on Saturday, poor weekend liquidity, and a possible trend change on Monday
Resistance above: 78,300–78,800 → 80k → 81k–81,500 (critical line) → 83,000–86,000
Support below: 76,800–77k (Friday’s low) → 75k–75,500 → 73,000 → 69,000–70,000 (200-day moving average)
Trading strategy
Bullish approach:
Go long with a light position on a pullback to 76,800–77,200, with a stop-loss at 76,400 or 75,500; target 78,300–78,800, with a second target of 79,800–80,200. Consider adding only after holding above 80,000, targeting 81,000.
Bearish approach:
Only consider shorting after an effective break below 76,800 (confirmed by a 4-hour close plus increased volume), targeting 75,500 → 73,000. Don’t actively open shorts at 77,700; weekend liquidity is thin, and a false breakout could easily trigger your stop-loss.
Breakout strategy:
A daily close above 81,100 followed by a successful retest is the only genuine trend-reversal signal.
Position-sizing rules:
Risk no more than 1–1.5% of your capital per trade
Keep leverage within 5–10x, and lower on weekends
Monitor funding rates; positive long funding plus rapidly rising OI means beware of a long squeeze
Don’t hold a heavy position overnight before Monday’s open
August’s rebound was of decent quality, and institutional buying is real, but the $81,000 hurdle (the upper trendline, 50-week moving average, and supply zone) has not been cleared, while the macro backdrop has suddenly turned hawkish again.
Around $77,700 is a “wait-for-direction” level, suitable for range trading but not for betting on a direction.
First, watch whether $76,800 holds. If it does, continue grinding sideways and choose a side afterward; if it doesn’t, reduce your position and wait, then reassess around $75,000.
The market will give you a second chance. Those who rush to go all-in on the weekend are usually no longer around ten years later.
On the day $81,000 breaks, you’ll realize:
It wasn’t that BTC was incapable—it was that you chased every time at $80,000 and sold at $77,000.
