The Canadian Bitcoiners Podcast - Bitcoin News With a Canadian Spin

Coldcard vulnerability explained: $89 million in Bitcoin gone in four days — the thief never touched a device.Full show notes & past episodes → https://canadianbitcoiners.comCoinkite is a Toronto company. The Coldcard is the Bitcoin hardware wallet serious self-custody people trust. On July 30th an attacker swept 1,082 BTC out of 1,196 addresses in 41 minutes, then kept going. Block's engineers found the cause: one mis-written line in Coinkite's own library meant Coldcards had been generating seeds from a predictable number generator instead of the hardware chip. Since March 2021. Nineteen hundred and sixty-one days.Nobody was hacked. No device opened, no server breached, no malware installed. The keys were calculated offline from public data, and the blockchain checked which guesses had money on them. If you rolled 50 or more fair, private dice rolls setting your Coldcard up, Coinkite says that seed isn't at risk from this bug. If you didn't, move your coins.In this episode of the Canadian Bitcoiners Podcast:— How one keyword collapsed seed entropy from 128 bits to roughly 40 on Mk2/Mk3 (about 72 on Mk4, Mk5 and Q)— Why "Coldcard was hacked" is the wrong headline, and why the distinction matters— NVK: "I'm sorry and I'm devastated" — and the AI excuse nobody's buying— The 2021 commit that shipped seed-generation code with no pull request— Coinkite emailing customers back to 2019, and the privacy problem that raises— SparkKitty malware reading photo galleries for seed phrase screenshots— Apple sued for $1.8M over a fake Sparrow Wallet that passed App Store review— Celsius' old mining rigs became an AI data centre, listed at $2.8B— Bitcoin Independence Day: what August 1st still means nine years on— Ford and Piccini's $11,700 Disney trip, Grewal's ads in his father's paper— The Supreme Court tells Parliament it can't put a watchdog beyond the courts— Groceries top what's draining Canadian bank accounts: 76% say so— 50,000 applications for 700 CNE jobs, realtor counts falling, Peel shootings up— Chow vs. Ford on the waterfront, Billy Bishop, and the Alto deal falling apart— Ottawa bought 3,196 motorbikes for Ghanaian farm agents and never budgeted the gas— New York's municipal grocery stores at 30% offSelf-custody didn't fail this week. A software supply chain did. Dice, passphrases, verification and multisig exist for exactly this — and the people who used them still have their Bitcoin.— Canadian Bitcoiners Podcasthttps://canadianbitcoiners.com — subscribe and turn on notifications for the Monday show.#Bitcoin #Coldcard #CanadianBitcoiners #Coinkite #SelfCustody #MSTR #BitcoinNews #BitcoinCanada————————————————————————————————SPONSORS🔒 easyDNS — Canadian-owned, ICANN-accredited registrar that has accepted Bitcoin since 2013.

🚨 URGENT BITCOIN SECURITY ALERT 🚨A critical security flaw has hit older Coldcard hardware wallets, resulting in a massive on-chain sweep where roughly 594 BTC (valued at over $38 million) was stolen from hundreds of single-signature wallets. Coinkite has issued an urgent warning regarding Coldcard Mk3 devices (and certain firmware versions) where the device generated entropy was dangerously low....dropping from the expected 128 bits down to roughly 40 bits.In this live stream, we break down:• Exactly what went wrong with the Coldcard Mk3 random number generator (RNG) / entropy fallback.• How attackers were able to brute-force and sweep vulnerable wallets.• Which models and firmware versions are affected (Mk3 vs. Mk4/Mk5/Q).• Step-by-step instructions on what you need to do RIGHT NOW if you generated a seed on an affected device.• Temporary mitigations (like strong BIP-39 passphrases) vs. permanent migration.Don't panic, but take action immediately.

Nine of the biggest names in finance put up $15 million between them. IBM alone is spending $10 billion.On July 23 the Bitcoin Security Consortium launched: BlackRock, Coinbase, Strategy, Block, Blockstream, Anchorage Digital, ARK Invest, Fidelity Digital Assets and Galaxy, pledging $15 million over three years for post-quantum research. There is no pooled fund and no governance role over the protocol — every firm writes its own cheques, and Brink's Mike Schmidt coordinates the whole thing as an unpaid volunteer. Joey and Len take the obvious objection seriously and then take the other side seriously too, because that structure was built specifically to make capture harder, not easier.The number everyone will repeat is 6.9 million BTC — roughly $460 billion — sitting in address types a working quantum computer could empty. That's a Google Quantum AI estimate, and estimates vary widely: other researchers put the exposed share anywhere from 20% to 50% of supply. No such machine exists. Adam Back says decades. Project Eleven's CEO says 2029 worst case, 2033 base case.Then: Jack Mallers walks away from Twenty One Capital and the treasury model keeps coming apart — Satsuma liquidating all 668 BTC, Sequans down more than 80%, Strategy selling 3,588 coins to fund a dividend. And CertiK's numbers on physical attacks against holders, including Canada's own file.Plus Clown World North: a Vancouver council hearing took public comment from Los Angeles, Ottawa waived the reporting requirements on a $12.1 million grant that has produced zero excavations in five years, and Alberta pulled a 2.4-pound goldfish out of a stormwater pond.The Canadian Bitcoiners Podcast - New episodes weekly.X: https://x.com/CanadianBTCPodJoey: https://x.com/joeytweeetsLen: https://x.com/thebtcpricebotSite: https://canadianbitcoiners.com#Bitcoin #BitcoinSecurity #Quantum #Canada

Michael Saylor's "never sell" era is OVER. Strategy sold 3,588 BTC (~$216M) at a 20% loss to cover $1.8B in dividend obligations — and Canadian pensions are holding close to $1B of MSTR stock. On June 29, Strategy's board adopted its "Digital Credit Capital Framework": $1B stock buybacks, a 12% STRC dividend, and a $1.25B "BTC Monetization Program" authorizing Bitcoin sales "when strategic." CEO Phong Le calls it "evolving from one-way capital issuance to active capital management." The mNAV premium that financed five years of buying has collapsed from 2.66x to around 1x — and one in three Bitcoin treasury companies now trades below the value of its coins. In this episode of the Canadian Bitcoiners Podcast:- Strategy's pivot: the mNAV death spiral, coins sold at a 20% realized loss, insider selling, and JPMorgan's $2.8B-$11.6B index-exclusion warning- The Canada connection: CPPIB, AIMCo, National Bank, RBC and HOOPP hold ~$1B of MSTR — your pension bought the wrapper trade- A quantum-proof recovery tool that works for everyone except Satoshi's 1.1M BTC- OkoBot: malware that fakes your Ledger/Trezor recovery screen- Global hashrate is shrinking — but Pakistan is up 733%- CleanSpark signs a $6.6B, 20-year AI data center lease- Canada bans crypto political donations under Bill C-25- Clown World North: Stan Cho's $16,203 hotel bill, Canada Post's $30.8M in bonuses against a $1.57B loss, and $159,800 in flight catering- The BIS confirms Canada's housing crash is the biggest on record as 56,400 Canadians leave in a year The leverage cycle is unwinding — the conviction cohort isn't. Long-term holders just hit a record 14.85M BTC. ETF outflows and treasury-company stress are paper Bitcoin changing hands; the base layer doesn't care.
