Bitcoin-specific news — protocol activity, scaling layers, and BTC-centric applications.
The 55% surge in on-chain activity is the cleanest real-time signal that the Coldcard breach is forcing users to move funds, not just talk about it.
BTC trades at one of the deepest discounts to its logarithmic regression fair value since the asset's first years, and the channel argues the four-year cycle still points lower before any fresh bull…
The transfer comes from a corporate treasury that built its BTC position through 2025, and exchange deposits of this size from a public-company holder typically precede either a sale or a strategic…
The real question is not if institutions sell, but how much: Terpin argues their flows set the marginal price floor, so every quarterly treasury disclosure is a macro signal.
Strategy's BTC Yield has rolled over, Metaplanet trades below the value of its own holdings, and the playbook of raising equity to buy more Bitcoin is breaking in front of retail.
A March 2021 firmware flaw keeps paying out three years later, and the attacker is now grinding smaller balances through a third wave that hides its collector addresses.
Roughly $38M has been swept from single-sig seeds generated between 2021 and 2023, and the exploit is unpatchable by design: any firmware fix would tip off attackers to wallets still holding funds.
The seed-randomness flaw had lurked in firmware since March 2021 and went unnoticed for years, exposing the practical ceiling of single-device self-custody for serious BTC holders.
Galaxy mapped the July 30 sweep to 1,196 wallets and 1,082 BTC drained in 41 minutes via a seed-generation bug that collapsed the keyspace to a few billion options.
Nearly 1,200 addresses and 1,000 BTC later, the incident has crossed from isolated phishing to a coordinated drain, putting self-custody users on notice about supply-chain risk in hardware wallets.
TD Cowen and Benchmark keep buy ratings on MSTR after Q2, but split on price as the $8.2B loss and a five-week BTC buying pause push STRC preferred back to par as the main goal.
Krishna's timeline pulls commercial quantum computing inside the half-decade window, with Alphabet, IonQ and Rigetti in the race and crypto watching the long-term encryption threat.

OFAC's designation of Persian Gulf Marine Insurance and HormuzSafe puts every foreign shipper paying in BTC on the wrong side of US secondary-sanctions exposure, in a chokepoint already pricing…
Bitcoin beat both the average and median Top 100 altcoin returns in July, but the dominance chart still anchors the broader picture despite headline-driven altcoin winners.
A three-year gap between Coldcard's final Mk3 firmware and the advisory turns dormant cold-storage wallets into a maintenance liability, with one signature and no passphrase as the worst-case custody…
The $38M theft from a single compromised wallet makes this the largest hardware-wallet supply-chain attack on record, with Coldcard pointing users straight at a firmware load-bearing weakness.
The single-signature wallets swept had been dormant for years, but the underlying firmware bug has been live since March 2021, with paper wallet keys and seed-splitting masks exposed too.
Roughly 500 wallet addresses were drained in a pattern tied to a Mk3 firmware bug, putting the total stolen above $35M and forcing Coinkite to flag every device that ever generated a seed on 4.0.1 or…
