Bitcoin (BTC) Breaks $78,000 as Overbought Rally Sparks Pullback Fears

Bitcoin (BTC) climbed past $77,000 on a fifth consecutive daily gain, with spot exchange-traded fund inflows accelerating and major altcoins such as Ethereum and XRP advancing in sympathy. The crypto Fear & Greed Index rose to 72 from 62, signaling expanding risk appetite. Data show US spot Bitcoin ETFs absorbed roughly $606 million on the latest session, lifting the four-day net inflow total to about $1.6 billion. The extended advance pushed the three majors into overbought territory, with Bitcoin's relative strength index reading near 85, leaving momentum strong but short-term exhaustion risk building.

VanEck head of digital assets research Matthew Sigel reiterated his bullish outlook, telling CNBC he still expects Bitcoin to reach $100,000 within the next year and to potentially hit $500,000 by 2029 if historical market cycles repeat. Sigel's thesis rests on supply dynamics following block-reward halvings, sustained institutional demand, and a favorable US regulatory backdrop. He acknowledged that a $100,000 target requires a substantial move from current levels, while the 2029 goal assumes a full-blown bull market comparable to prior cycles. Analysts note the prediction sits within Wall Street's broader range, though timing differences remain significant.

Speaking on CNBC this week, Sigel maintained his 2027 target of $100,000 and a 2029 cycle peak of $500,000, even as VanEck's mid-August Chaincheck report flagged persistent stress. That report showed 8 of 12 surrender signals triggered as of August 18, with long-term holders offloading 356,000 BTC in 30 days and their share of total supply dropping below 60% for the first time in months. VanEck's longer-dated case also leans on the proposed 2024 Bitcoin Act, which would direct the US Treasury to buy up to 1 million BTC by 2029, roughly 4.8% of supply, creating what the firm calls a self-reinforcing sovereign demand loop.

Bitcoin's spot price touched nearly $79,500 intraday before settling back under $78,000, extending a 24-hour gain of more than 13%. The volatility roiled derivatives markets, with aggregate liquidations surpassing $330 million in a single hour and closing in on $1.5 billion over 24 hours. Data show over 170,000 traders were wiped out, with roughly $825 million of the total tied to Bitcoin positions. The largest single liquidation order, valued at $23.59 million, occurred on Hyperliquid, underscoring how leveraged positioning has amplified both directions of the move.

The US Treasury said Wednesday it will double the size of its long-term bond buybacks to at least $4 billion per operation from September 9 through November 4, financing them with short-term debt rather than newly created money. Officials framed the action as a liquidity-management tool, not quantitative easing or formal yield-curve control, though analysts increasingly describe it as a modern 'Operation Twist.' The signal that policymakers are uneasy with elevated long-term yields helped push Bitcoin above $77,000 and gold higher, while the dollar weakened. The weekly gain of roughly 23% was the largest for Bitcoin since March 2023, according to market data.

Bitcoin subsequently broke $78,000, with $442 million in short positions liquidated within 24 hours as forced buybacks amplified the advance. Its one-week correlation with gold reached 88%, pointing to macro flows as much as crypto-specific demand behind the rally. On the policy front, President Trump met with crypto executives and pushed for passage of the CLARITY Act market-structure bill, while a Senate vote on the legislation is expected around September 15. Prediction markets remain cautious, with Polymarket pricing a 73% probability of $80,000 by year-end but only a 38% chance of $90,000.

COINOTAG's proprietary 42-indicator composite scoring engine rates the $78,568 resistance at 77/100 (STRONG), driven by the confluence of the R3 pivot, a Fibonacci 0.886 retracement, low-volume node, and relative-strength overbought readings. The key support at $76,842 scores 72/100 (STRONG), anchored by a flip from resistance to support, Fibonacci 0.786, and an ATR-lower band. With RSI at 85.74, MACD bullish and the trend structure firmly up, derivatives positioning shows a funding rate of 0.0064%, open interest of $15.16 billion, and a long/short account ratio of 1.07 (51.6% long). The Fear & Greed reading of 72 (Greed) supports the constructive case. A sustained hold above $76,842 keeps the bullish scenario intact toward $82,048, while a break below that support would open the path toward $72,726 and risk a return to bear-market conditions, invalidating the immediate thesis.
