What is the bitcoin quantum computing risk?

Attackers could use advanced quantum machines to derive private keys from exposed public keys. Around 7 million BTC are in that category, including some Satoshi-era coins. If stolen, confidence could drop fast, fees could spike, and prices could swing widely. Custody upgrades and planned migrations aim to reduce that risk.

How could Satoshi coins risk trigger a Bitcoin supply shock?

If early coins move without warning, markets may assume theft or distressed selling. That could push holders to hedge or exit, widening spreads and amplifying volatility. If, instead, those coins migrate in an orderly way to safer addresses, circulating supply could tighten and support prices instead of hurting them.

What should Swiss investors ask custodians today?

Request details on hardware security, multi-signature policies, key rotation, and quantum-safe plans. Ask for incident response steps, insurance coverage, and how redemptions work during extreme events. Confirm monitoring for exposed-key UTXOs and Satoshi-era movements. Clear, written procedures help reduce operational risk if threats escalate quickly.

Does today’s BTCUSD technical picture point to more downside?

Signals are mixed. RSI near 30 suggests oversold, while ADX above 50 shows a strong trend. Price sits below the 50‑day average and near lower channels, so rebounds can fail until momentum improves. Use ATR to size risk and watch for closes back above the middle Bollinger band.

Are quantum-safe upgrades for Bitcoin close?

Research into post-quantum signatures is active, but broad deployment needs review, testing, and consensus. Any change must protect users without splitting the chain. For now, best practice is moving funds to fresh, non-exposed addresses and pushing custodians to publish quantum-readiness roadmaps.
