Bitcoin News Today: Quantum-Safe Transaction And Bernstein Prediction
Bitcoin News Today: Quantum-Safe Transaction, 150K Forecast, US Moves
Bitcoin News Today carries two very different threads at once. A StarkWare researcher just mined the first confirmed quantum-safe BTC transaction, while Bernstein raised its Bitcoin price prediction toward $150,000 by mid-2027.
So what actually defines Bitcoin's next move: quantum-safety progress, bullish forecasts, or drop risk tied to US government selling pressure? A look at each piece helps answer that.
BTC Quantum Safe Milestone: First Transaction Mined on Mainnet Now
StarkWare researcher Avihu Levy's Quantum-Safe Bitcoin scheme, known as QSB, achieved its first confirmed mainnet transaction on August 26 and 27, 2026. The method swaps elliptic-curve cryptography for hash-based security.
It requires no soft fork or change to $BTC's consensus rules, per StarkWare's own blog post. This technical thread is one of the bigger stories inside $BTC news today.
How it works: security rests on hash pre-image resistance, roughly 118-bit under current threat models
What it costs: about $75 to $200 in off-chain GPU computation per transaction
How it gets sent: direct miner submission, since the format skips standard mempool relay
Why it matters: it protects only outputs migrated into the scheme, not Taproot, Lightning, or already-exposed keys
StarkWare calls QSB an interim lifeboat rather than a permanent fix, while still favoring a protocol-level soft fork as the long-term answer for keeping Bitcoins quantum safe.
Bitcoin's Quantum Position in 2026: Threat Level and What Works Now
No cryptographically relevant quantum computer exists today, and Bitcoins faces no immediate danger. Current leading hardware holds roughly 1,000 to 1,200 physical qubits.
Breaking Bitcoin's signatures would likely require between 1,200 and 2,300 logical qubits, or close to 500,000 physical qubits, based on Google Quantum AI analysis from March 2026.
Exposed supply: roughly 6 to 7 million BTC, about 30% of circulating supply, already has public keys visible on-chain
Irreducible coins: around 2.3 million BTC sit in dormant or lost wallets
Mining security: SHA-256 proof-of-work stays largely safe, since Grover's algorithm only offers a quadratic speedup
Timeline estimates vary widely, from roughly a 10% chance of key recovery by 2032 to a 20-to-40-year horizon in more conservative views. Proposals like BIP-360 and Blockstream's SHRINCS scheme aim to build post-quantum protection into the protocol over time.
Bitcoin News Today: BTC Price Today Holds Steady Near $79,700 Now
Bitcoin price today sits near $79,503, up 1.34% over 24 hours, tracking a similar 1.2% rise across the broader crypto market. Current states as per CoinMarketCap:
BTC price: $79,503.41, up 1.34% in 24 hours
Market cap: $1.59 trillion, up 1.1%
24-hour volume: $31.38 billion, down 5.6%
Fully diluted valuation: $1.66 trillion
Spot Bitcoin ETFs logged an eighth straight day of net inflows, a trend that keeps shaping Bitcoin news today.
Moving ahead, two major factors are defining the BTC price in two different paths: Bernstein's bullish BTC price prediction, and a fresh US $BTC move that has traders weighing renewed selling risk.
Bernstein Bitcoin Price Prediction: $125,000 by the 2026 End
Bernstein, a global equity research and brokerage firm, analysts see $BTC reaching around $125,000 by the end of 2026, with a Bitcoin price prediction of $150,000 by mid-2027. This cycle will peak near $300,000 in 2029.
A faster debasement scenario could push targets to $200,000 by mid-2027. The firm also trimmed its price target on Strategy from $450 to $350.

Bernstein BTC price prediction major findings:
End of 2026: roughly $125,000
Mid-2027: $150,000
2029 cycle peak (base case): around $300,000
Faster debasement scenario: $200,000 by mid-2027, $500,000 by 2029
Long-term 2033 target: near $1 million
Strategy price target cut: from $450 to $350, citing a revised $BTC cycle outlook
Separately, a US $BTC move drew attention in bitcoin news today after the government shifted BTC seized from Alameda-linked accounts as per Arkham data. It raises questions about further liquidation and added selling pressure.
BTC recently climbed back to the $80K range after months of failed attempts. The US Bitcoin-tied move risk factor sits right alongside that recovery. The current transfer was small, but it raises the question of further liquidation of Alameda's remaining Bitcoins.
A large-scale government selling move could add pressure to the overall crypto market.
In The End: What the Bitcoin News Today States?
Bitcoin news today shows a market holding two stories at once. Quantum-safety work like QSB adds long-term groundwork without touching consensus rules. Price action stays tied to macro flows, ETF demand, and analyst forecasts rather than any single catalyst.
Neither the quantum threat nor a government sell-off looks imminent right now, but both remain worth tracking into the year's final stretch.
