比特币价格跌破77,000美元：本周比特币价格为何出现大幅下跌？?

[라온]

Bitcoin price slipped to nearly $77,000 this week, extending its decline for a fourth straight day as selling pressure intensified across crypto markets. The latest downturn comes amid heavy Bitcoin ETF outflows, rising spot-market selling, and a sharp shift in trader sentiment, with fear returning to crypto discussions for the first time in weeks.

Meanwhile, Bitcoin has started losing momentum after failing to sustain its recent push above the $81,000 resistance zone, raising fresh concerns about whether the market is entering a deeper correction phase.

So, why did Bitcoin price fall this week, and what exactly is driving BTC’s latest selloff? Here are the key reasons behind the market weakness.

Spot Selling Appears to Be Driving BTC Lower

On-chain analysts suggest Bitcoin’s decline has not been fueled by panic in leveraged futures markets. Open interest across Bitcoin derivatives remained largely stable during the recent drop, indicating traders are not aggressively unwinding long positions. Instead, spot exchange inflows and rising sell pressure appear to be behind the latest weakness.

Data circulating across crypto markets shows Bitcoin inflows into exchanges surged during the correction window, typically a signal that holders may be preparing to sell. At the same time, spot trading activity accelerated as BTC slipped below short-term support zones. Historically, futures-led selloffs often reverse quickly after liquidations clear excess leverage. Spot-led corrections, however, can last longer if buyer demand weakens.

Bitcoin ETF Outflows Add Pressure

Institutional sentiment also appeared softer. U.S. spot Bitcoin ETFs reportedly registered around $649 million in net outflows on May 18, adding another layer of downside pressure to BTC.
BlackRock’s IBIT ETF alone accounted for nearly $448 million in withdrawals, even as on-chain trackers flagged a separate transfer of roughly 5,847 BTC (worth about $449 million) to Coinbase Prime, sparking debate across crypto communities over whether the movement reflects custody reshuffling or active selling pressure. The heavy ETF outflows arrive at a sensitive moment for Bitcoin, especially after months of sustained institutional accumulation that had helped fuel upside momentum.

Fear Returns to Crypto Markets

Retail sentiment has also turned noticeably cautious. Market intelligence platform sentiment data showed bearish Bitcoin commentary overtook bullish sentiment for the first time since April, signaling growing fear across crypto social channels as BTC revisits lower levels.

Ironically, extreme fear has historically acted as a contrarian signal for Bitcoin. Previous periods of heightened pessimism have often preceded relief rallies once weaker hands exit the market. Still, sentiment alone may not be enough to reverse the trend if selling pressure continues to outweigh fresh demand.

Bitcoin Price Outlook: Can BTC Hold $75K?

Bitcoin price appears to have rejected near the $81,700 resistance zone, triggering renewed downside momentum. BTC is now approaching a critical support area near $72,000–$75,000, a region that previously acted as a strong accumulation zone. A decisive breakdown below this range could expose Bitcoin to a deeper correction toward lower demand areas.

On the upside, Bitcoin must reclaim $81,700 to invalidate immediate bearish pressure. If buyers regain control, the next major resistance sits near $95,000, followed by the broader psychological target around $107,000. For now, traders remain focused on whether Bitcoin can stabilize above support or if the current four-day slide has further room to run.

Will Bitcoin Price Bounce or Fall Further?

Bitcoin’s latest drop appears to be a mix of spot-market selling, ETF outflows, and weakening short-term sentiment, rather than panic liquidations in futures markets. That distinction could shape what happens next. If BTC manages to hold the $76K support zone, growing bearish sentiment may paradoxically fuel a rebound as contrarian buyers step back in. However, a breakdown below key support could intensify downside pressure and shift attention toward deeper correction targets in the days ahead.
