Quantum Computing Advances Cast a Bearish Cloud Over Bitcoin’s Security

Quantum Computing Advances Cast a Bearish Cloud Over Bitcoin’s Security. Bitcoin (BTC) faced renewed bearish pressure this week as growing concerns over quantum-computing threats unsettled market sentiment. Analysts warn that the cryptocurrency’s underlying security model—long regarded as practically unbreakable—could face unprecedented risk as quantum machines advance rapidly from theoretical concepts to functioning prototypes. The exposure is particularly alarming given the vast trove of untouched Bitcoin, estimated at $67–$124 billion, still secured by early cryptographic standards.

For physicists and cryptographers, this dormant supply is not merely a historical artifact but a potential vulnerability point. If quantum technology gains enough power to compromise older encryption methods, Satoshi’s unmoved coins and the broader Bitcoin network could face significant security challenges. With global governments and major tech companies heavily funding quantum-research initiatives, the threat is shifting from hypothetical to increasingly plausible. Until stronger quantum-resistant defenses are fully developed and adopted, Bitcoin may struggle to maintain investor confidence, keeping its outlook tilted to the downside in the long term.

Key Bitcoin Levels To Watch – November 16

BTCUSD remains locked in a clear bearish structure, with price trading below the descending trendline and the 9-day SMA. Recent candles show weak bullish attempts, indicating sellers are still firmly in control.

If the pair fails to reclaim the $99,360–$102,110 zone, downside continuation toward $92,000 and potentially $85,010 becomes likely. RSI hovering near oversold levels reflects persistent bearish momentum rather than a confirmed reversal.
