Attacking bitcoin mining with a quantum computer would require the energy of a star, academics say

Academics have calculated that launching a successful quantum computing attack on Bitcoin’s mining infrastructure would demand energy levels comparable to total stellar output, making such a threat effectively implausible with any foreseeable technology. This finding reinforces confidence in Bitcoin’s cryptographic security model, particularly its resistance to brute-force and quantum-based computational attacks on SHA-256 and elliptic curve digital signatures. The analysis supports continued trust in BTC as a long-term store of value by mitigating concerns over existential technological risks tied to advances in quantum computing. Market exposure remains minimal, as the study downplays the near- or medium-term risk of quantum-enabled network compromise. Traders will watch future developments in quantum computing efficiency, particularly milestones in qubit stability and error correction, as indicators of potential long-term shifts in cryptographic assumptions.

Bitcoin (BTC) price action is driven by spot ETF flows (IBIT, FBTC, GBTC, ARKB), SEC enforcement actions, institutional adoption announcements, large wallet moves, and miner behaviour. BTC-specific catalysts include halving events every ~4 years.

HIGH-impact news is typically a market-moving event with multi-pip or multi-percent intraday reactions. Examples include central bank rate decisions, major CPI/NFP releases, geopolitical shocks, mega-cap earnings beats/misses, and regulatory announcements. Traders typically position-reduce or hedge ahead of scheduled HIGH-impact events, and follow the wire in real time to react to unscheduled ones (war headlines, central-bank emergency statements, surprise corporate actions). The Trading News Terminal squawk box reads every HIGH-impact headline aloud the moment it hits the wire — so active traders don't have to stare at the feed.

Active traders typically follow a three-step workflow when a market-moving headline hits the wire: (1) read the headline on the terminal or hear it on the squawk box; (2) assess whether the news is already priced in (by checking intraday price action in the seconds before) or whether it's genuinely new information; (3) act — either entering a breakout position, fading an overreaction, or tightening stops on existing trades. Trading News Terminal's Pro plan delivers wire-grade headlines within seconds of the source, with automatic audio squawk on every HIGH-impact event, so the read-assess-act cycle never waits on a refresh button.
