Bitcoin's digital signatures could one day be cracked by a powerful quantum computer. None exists yet, and the machines that do are thousands of times too small. Here is what is actually at risk, how far the hardware really is, and the fixes already being written.
Binance has told customers in France, Spain, Italy and Poland that it will start charging a monthly fee on November 29 and close their accounts on December 31, after missing the EU's MiCA licensing deadline. Withdrawals stay open until then.
US spot Bitcoin ETFs lost $1.28 billion in the week to November 6, 2026, almost all of it from BlackRock's IBIT. The headline looks like a wall of institutional selling. The detail is narrower, and it tracked a falling price more than it drove one.
A former FBI supervisory agent, Patrick Steven Yaroch, pleaded guilty to wire fraud and money laundering after stealing $2.47 million in cryptocurrency from wallets his bureau had seized across 35 investigations. Sentencing is set for March 4, 2027.
These companies exist to own bitcoin. They raise cash from shareholders and lenders, buy coins, and report how many they hold per share. Strategy started the model and holds the most by far. It prints value when the share price runs ahead of the bitcoin, and bleeds when it does not.
Zcash turned on its NU7 upgrade at block 3,543,405, cutting block times to 25 seconds and starting a fee reserve meant to pay for security after 2031. One old privacy pool holding about 12,224 ZEC is now frozen.
The Central Bank of Nigeria now licenses stablecoin issuers, with capital floors up to 15 billion naira and a ban on algorithmic coins. The rules took effect on 5 November 2026 and reach foreign issuers whose tokens are marketed to Nigerians.

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.
Binance says its commitment to Europe is unchanged and the wind-down is a carefully managed process with no sudden freeze.
Our read: Withdrawals do stay open and user balances remain accessible, so there is no freeze. But Binance holds no MiCA license in any EU state, pulled its only application in June, and will charge a monthly fee on anything left after November 29, so the exit is real and it costs users who wait.
Record Bitcoin ETF outflows show big investors are walking away from the asset.
Our read: US spot Bitcoin funds did lose $1.28 billion in the week to November 6, 2026, the heaviest in months. But almost all of it came from a single fund, BlackRock's IBIT, while Fidelity's FBTC took in money. Net flow totals hide gross trading, and the week tracked a broad selloff in technology stocks rather than a crypto-only exit.
Prosecutors say a former FBI counterintelligence agent used his access to seized wallets to steal $2.47 million in cryptocurrency across 35 investigations.
Our read: Yaroch pleaded guilty to wire fraud and money laundering on November 5 and the Justice Department put the total at $2,474,380.66. The admission is on the record. The sentence, final restitution and forfeiture figures are not set until March 2027.

Searches for a Bitcoin wipeout spike whenever the price drops. A fall to exactly zero would need a worldwide failure that has not happened since 2009, yet Bitcoin has still lost most of its value more than once. This guide separates a crash from a true zero.
