A quantum researcher has cracked a simplified Bitcoin key, accelerating the timeline for 'Q-Day' when quantum computers could threaten BTC security, according to Decrypt. This breakthrough highlights vulnerabilities in current cryptographic systems, echoing concerns from last year's quantum advancements that rattled the crypto market crash fears. Investors eye Bitcoin resilience, with parallels to TAO token's quantum-resistant hype driving alternative blockchain interest.

Zooming into the 4h chart, BTC trades at $78,080.75 in a bullish structure, hugging the EMA50 support at $76,400.78 while the EMA200 at $73,020.11 anchors longer-term upside. Yet MACD flashes a bearish death cross at 543.79, clashing with neutral RSI at 56.1—price squeezes inside Bollinger Bands, testing upper resistance at $79,743.1 as volatility builds. Confluence screams caution: if upside exhausts here, expect a sharp pullback to lower support at $75,591.3, setting up a classic retest before resuming the grind higher, much like the consolidation we saw in Q1 2026.
