Crypto execs advise that you head for the nearest bunker

Justin Drake warns AI could crack wallet cryptography "in months, not years." Vitalik agrees but says don't rush — he's lost more to bad migrations than hacks. And 6 million BTC already sit behind exposed keys. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ SPONSORED BY Thursday, October 8, 2026 Bitcoin and ether holders urged to enter 'bunker mode' against possible AI attacks Ethereum researcher Justin Drake is urging the industry to start preparing for "bunker mode" — warning that AI could find a shortcut to break the elliptic curve cryptography protecting bitcoin and ether wallets "in months, not years" in the worst case, well before quantum computers arrive. No practical attack has been demonstrated, but AI has already cost real money: Coldcard lost 1,367 BTC through a firmware bug suspected to have been found by AI, and BTCPay Server's Lightning nodes were drained through a flaw surfaced in an AI-assisted audit. Vitalik Buterin agrees the risk is real but cautions against rushing: "I have lost more money in botched migrations than I have lost in all hacks combined."

See how the fork works Markets Over 6 million bitcoin sit behind exposed public keys as AI warnings mount More than 6 million BTC — 31.2% of circulating supply — sit behind public keys already visible onchain, up 222,000 BTC since May according to Glassnode.

Did the U.S. just sell $100 million in bitcoin?

Wallets sent 833 BTC to Coinbase Prime — but under the Strategic Bitcoin Reserve order, the government isn't supposed to sell. Plus: Bitmine stops buying ETH at 5%, and GSR puts $100M onchain. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ SPONSORED BY Wednesday, October 7, 2026 U.S. government moves over $100 million in BTC and BNB — a sale hasn't been confirmed Wallets linked to the U.S. government moved 833 BTC ($71.6M) and 40,285 BNB ($31.6M) Tuesday, with the bitcoin ultimately routed to Coinbase Prime deposit addresses. The BTC came from the Potapenko/Turogin and Bitfinex hack forfeitures; the BNB from seized Alameda Research assets. No sale has been confirmed — under the March 2025 executive order, forfeited bitcoin is meant to be held in the Strategic Bitcoin Reserve, not sold. The government still holds roughly $27.5 billion in seized crypto. Read more → A message from eCash Bitcoin hasn't shipped a meaningful upgrade since Taproot in 2021.

Bitmine already holds 6 million ETH ($15.5B, 4.9% of supply) and has bought every week since June 2025, making it one of ETH's most consistent sources of demand. That demand ends soon, and it comes as ether is already down 5% today and sitting on $4.5 billion in unrealized losses. 2-minute read → Business GSR's new vault business is a $100M bet on onchain credit GSR is committing $100 million — mostly via credit facility — to Hare, a new onchain vault business built alongside liquidity platform Turtle. The model: GSR provides anchor liquidity into stablecoin and tokenized gold vaults before outside investors arrive, with Aave powering the first two products. As tokenization spreads, vaults are becoming the infrastructure that puts those assets to work rather than just holding them. "Issuers get liquidity from day one, and allocators see GSR's own capital in the same vaults as theirs," says Hare CEO Connor Milner. 2-minute read → Know someone who should be reading this?

Has this been bitcoin's most resilient bear market?

Down 32% from $126K — far shallower than the 70–82% drops of past cycles. ETFs, cleared leverage and structural changes explain it. But one analyst says don't get too comfortable. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ SPONSORED BY Tuesday, October 6, 2026 Why bitcoin is down 'just' 32% a year after its record high of $126,000 A year ago today bitcoin hit $126,000. It's now at $85,453 — down 32%. In past cycles, the one-year mark meant down 70–82%. The difference this time is structural: ETF money rebalances by construction, leverage was cleared out in a single day last October, and crypto-margined futures are at all-time lows. Calmer crashes, though, come with a cost — calmer rallies too. And one analyst's warning is worth reading: "The moment the shallow-drawdown story is loudest is usually when downside protection is cheapest."

Its next phase may be creating new markets around things that already exist — elections, private company valuations, commodity prices — making them continuously tradable for the first time. Altius co-founder Annabelle Huang argues the industry's long-term value proposition is increasingly informational: not "what new asset can we create?" but "what can we price that couldn't be priced before?" 4-minute read → Policy Self-styled 'Godfather' gets 6 years for $37 million Meta fraud scheme Adam Iza, 26, was sentenced to 78 months in federal prison for defrauding Meta of $37 million — gaining access to advertising accounts and credit lines, then selling that access to companies that billed clients for ads they never bought. He also hired off-duty LA County sheriff's deputies to intimidate rivals using confidential law-enforcement databases. The sentence runs concurrently with a 15-year term he received last month for an attempted bitcoin robbery. 2-minute read → Know someone who should be reading this?
