Bitcoin dropped below $77,000 on Sunday, trading at around $76,725 — a 0.80% decline. The cryptocurrency ended Saturday near $77,300 before slipping further in early Sunday trading.

Higher bond yields and expectations that interest rates will stay elevated are making dollar-denominated assets more attractive. This has kept pressure on Bitcoin and the broader crypto market.
CryptoQuant analyst Darkfost noted that Bitcoin market sentiment briefly climbed above 89 out of 100, entering what he calls “extreme greed” territory. That is the highest reading since March 2024.
The last time we saw such a bullish market sentiment was in March 2024.
This Bitcoin rally has sparked the strongest investor enthusiasm in the past two years.
This market sentiment index managed to reach a score above 89 out of 100, a value of extreme greed.

Darkfost said the sentiment has since cooled from its peak, even as Bitcoin tries to hold its current price level. He noted that extreme sentiment readings — in either direction — can appear around market turning points, though he made no specific price prediction.
For context, Alternative.me’s separate Fear & Greed Index stood at 63, rated “greed,” at the time of reporting. That index uses volatility, trading volume, social media activity, and search trends as inputs.

Thursday saw the largest single-day withdrawal at $282.7 million. ARK 21Shares’ ARKB led individual fund losses with $234.2 million for the week, while BlackRock’s IBIT lost a net $52.5 million over the four sessions.
Analyst Ted Pillows flagged concern on the weekly chart, writing that Bitcoin’s “$BTC weekly candle looks really bad” and that “if a weekly close happens like this, sellers will gain control.” His comment reflects the caution circulating among traders heading into the weekly close.

The Portfolio Case for Bitcoin
Bitcoin Suisse published its Crypto Wealth Management Report 2026, arguing that Bitcoin can add value to traditional portfolios. With AI investment concentrating exposure in a small number of tech companies and U.S. federal debt crossing $40 trillion, the firm says bonds no longer provide the same diversification they once did.
Their modelling showed that adding a 1% Bitcoin allocation funded from bonds lifts annualised portfolio returns from 6.2% to 7.2%. A 2.5% allocation pushes that to 8.6%.
Major U.S. hyperscalers are expected to spend over $800 billion on AI in 2026 and more than $1 trillion in 2027.
U.S. inflation data showed prices rose 3.4% over the 12 months to August, matching July’s rate. The Federal Reserve’s next policy meeting is scheduled for September 15–16.
Bitcoin’s 24-hour range on Sunday spanned roughly $76,393 to $79,607, with the price sitting near the lower end of that range.
