Quantum computers could one day crack the signatures that protect Bitcoin wallets. No machine is close yet. Here is what the threat is, which coins are exposed, and the defense work already under way.
A spot bitcoin ETF lets you track bitcoin's price inside a normal brokerage account, but you never hold the coins. Buying bitcoin directly puts the asset in your own custody. The choice comes down to control, cost and how much you want to manage yourself.
The European Banking Authority has made USDC the first stablecoin it supervises directly under Europe's MiCA rules. From 12 November, the EBA takes over checks on the token's reserves, capital and liquidity from France's ACPR.
Bitcoin fell below $81,000 in Asian trading on October 15 after US consumer inflation ran hotter than expected for September. Ether and XRP slid more, and about $483 million in crypto futures bets were liquidated in a day as traders cut their bets on a Federal Reserve rate cut.
A bitcoin treasury company is a listed firm that holds bitcoin as its main reserve asset, raising money through shares and debt to buy more. Here is how the model works, where it started, and why the mNAV premium that drives it can turn into a trap.
Dubai's VARA cleared the bank to offer direct bitcoin and ether trading to professional investors, who can now buy and sell the coins from their Standard Chartered accounts. The bank calls it a global first for its wealth business.
There is no single ruling. Some Islamic authorities, including Indonesia's Ulema Council, have called Bitcoin forbidden. Others, including a widely cited 2018 study, treat buying and holding it as allowed. The split turns on speculation, uncertainty, and what counts as money.

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.
Europe has brought the world's second-largest dollar stablecoin under its toughest tier of direct supervision.
Our read: The EBA's own press release confirms the classification and the 12 November handover, so the core facts are solid. The regulator did not publish the figures behind the decision, and the label changes nothing for how USDC is used day to day. Its practical bite depends on reserve rules still under consultation.
Hotter US inflation has turned the market lower, and some analysts see Bitcoin heading toward $65,000 if support gives way.
Our read: The sell-off and the 3.7% September inflation print are confirmed by on-record data and two independent outlets. The $65,000 figure is one analyst's conditional technical call, not a consensus, and price forecasts like it are often wrong. The widely shared claim of nearly $1 billion liquidated is not supported by the CoinGlass data, which showed about $483 million.
Issuing stock to buy bitcoin steadily grows the bitcoin backing each share and rewards shareholders.
Our read: It works only while the stock trades above the value of the coins. Once that premium fades, as it did for many firms through 2025 and 2026, new share sales dilute holders and debt taken on to buy bitcoin becomes a forced-selling risk. There is no single agreed mNAV formula, and trackers disagree on the totals.

Quantum computers could one day crack the signatures that protect Bitcoin wallets. No machine is close yet. Here is what the threat is, which coins are exposed, and the defense work already under way.
Coinbase, the custodian of roughly 5% of all bitcoin, published a paper on 13 October urging developers to start building quantum-resistant defenses now. No computer can break bitcoin today. The company says the fix could take years, so the clock has started.
Bitcoin Core 32.0, the software behind most Bitcoin nodes, is due on October 10, 2026. It brings faster block validation, a mempool based fee estimator and two security fixes, including a memory bug that could push a node to 3.2 gigabytes of memory use. Consensus rules do not change.
A bitcoin treasury company is a listed firm that holds bitcoin as its main reserve asset, raising money through shares and debt to buy more. Here is how the model works, where it started, and why the mNAV premium that drives it can turn into a trap.
Dubai's VARA cleared the bank to offer direct bitcoin and ether trading to professional investors, who can now buy and sell the coins from their Standard Chartered accounts. The bank calls it a global first for its wealth business.
Polygon Labs completed its acquisition of Coinme on October 14, bringing money transmitter licenses in 48 US states into its Open Money Stack. The integrated payments product is still in technical preview.
Solana will switch on its Alpenglow upgrade on October 21, replacing the TowerBFT voting system it has run since 2020 and targeting transaction finality of about 150 milliseconds, down from roughly 12.8 seconds. SOL holders need take no action.
The onchain contracts stay live, but Blur's website and its Blend lending service both close on November 12. Monthly trading volume had already fallen from $1.43 billion to under $7 million.
XRPL developers disclosed and fixed a payment engine flaw, hidden since 2015, that could have created XRP far beyond the network's 100 billion supply cap. The patch shipped in xrpld 3.4.1 on September 25, and RippleX says no public network was attacked.

Bitcoin climbed back above $84,000 on Monday after sliding to about $80,350 last week, with short sellers, not new buyers, behind the bounce. Traders now look to Wednesday's US inflation report.
