Bitcoin: Quantum Threat Emerges by 2030

A new report warns that the quantum threat to blockchain networks like Bitcoin and Ethereum might strike as early as 2030, slashing previous timelines and igniting urgent debates on post-quantum cryptography upgrades amid rising crypto quantum computing risk.

On the 4h BTC chart, price action at $81,212.19 clings to a bullish structure, grinding above the EMA50 at $79,541.38 and well clear of the EMA200 at $75,596.13, but that MACD death cross with a reading of 696.3 screams bearish momentum—expect a probe toward the lower Bollinger support at $79,245.52 before buyers reclaim control, especially with RSI neutral at 56.13 and no overbought exhaustion yet, setting up confluence for a tactical dip-buy if volatility contracts inside the bands toward upper resistance at $82,657.47.
