A quantum computer could in theory pull a Bitcoin private key from its public key, but the hardware is nowhere close. Breaking one key in a day would take an estimated 13 million qubits. The best public chip has 105. Here is the real risk and the real timeline.
Crypto crashed hard again and the obituaries came out on cue. A price drop is not the same as death. The usage data tells a different story from the charts, and the gap between the two is the point.
South Africa's FNB has started selling bitcoin and four other coins to its customers through the exchange VALR, with buys from R10. There is a catch. The coins cannot be moved to an outside wallet, so holders get price exposure, not self-custody.
Strategy added just 334 bitcoin in the week to October 4, one of its smallest buys of 2026, while spending $73.7 million on preferred share buybacks and $142.5 million on preferred dividends. It still holds 848,000 BTC, the largest corporate stash on record.
A Bitcoin treasury company is a public firm that holds bitcoin as a core reserve and funds more buying by selling shares or borrowing. The model grows when the stock trades above the value of its coins, and stalls when it falls below. Here is how it works, and where it breaks.
The failed Tokyo exchange faces a final October 31 deadline to repay its creditors. On-chain data shows about 34,387 bitcoin, close to $2.9 billion, still sitting in the estate's wallets, and the trustee says many of the people owed have not finished the steps needed to collect.
Mining bitcoin in 2026 means industrial-scale power, a 3.125 BTC block reward split across the network, and machines that run at 15 joules per terahash. Here is what decides whether a miner makes money, and why even the biggest public miners lost money this year.

Quantum computers are close to breaking Bitcoin and stealing coins from any wallet.
Our read: Breaking Bitcoin's 256-bit elliptic curve keys is thought to need around 2,000 error-corrected qubits, which by one CoinShares estimate means about 13 million physical qubits to do it inside a day. The largest public chip, Google's Willow, has 105. Most researchers place a capable machine in the 2030s or later, and none exists now.
A major South African bank is giving everyday customers safe, simple access to crypto through its own app.
Our read: The launch is real and confirmed by FNB's own statement and several outlets. But access is limited. Holders cannot withdraw their coins or self-custody, only five assets are offered, and the bank has disclosed no fee schedule. The retail client figure of close to nine million comes from press reports, not FNB's statement.
Strategy remains the dominant corporate bitcoin buyer and its treasury model keeps working.
Our read: It does hold 848,000 bitcoin, the most of any public company. But last week's buy was just 334 coins, and it spent $73.7 million on preferred buybacks and $142.5 million on dividends, well above the $28.7 million it put into bitcoin. The filing gives no reason and no timeline for a bigger buy.
Mt. Gox's final repayment will flood the market with tens of thousands of bitcoin and push the price down.
Our read: The estate's large transfers in November 2025 and June 2026 went to new addresses it controls, not to exchanges, and were read as administrative steps before payout. Many creditors held through earlier distributions. No data yet shows how many of the roughly 34,000 remaining coins will be sold, and the trustee has not said how many creditors chose bitcoin over cash.

Brevan Howard, a hedge fund managing about $35 billion, will route prime brokerage, clearing and financing through Ripple Prime, deepening a tie that began when it backed Ripple's $500 million funding round in 2025.
Ondo Finance opened a platform for trading tokenized notes tied to private companies, starting with an unnamed pre-IPO artificial intelligence firm. The notes are not shares, and only investors outside the United States can buy them.
The DeFi lender's community is deciding whether to hand Sentora control of a new lending market on Aave V4. The pitch is a 50/50 revenue split at no cost to the DAO. The catch sits with the people who supply the funds.
Ethereum's Glamsterdam upgrade activates on the Sepolia test network on October 6, 2026, in its first public trial. The release moves block building into the protocol and opens a path toward a 200 million gas limit, though the mainnet date is still unset.
NEAR Intents clawed back all $3.8 million drained in an October 1 exploit after giving the attacker 48 hours to return it. The funds came back on October 2, and the protocol closed its investigation without naming who was behind the theft.

Winklevoss Asset Services filed a preliminary S-1 with the SEC on October 6 for a spot Zcash fund that would trade as WINK on Nasdaq at a 0.25% fee. It is the third US issuer to seek a Zcash ETF, and it lands while a government shutdown has frozen SEC reviews.
