The reward for mining a block is cut in half every 210,000 blocks. It has happened four times, the subsidy is 3.125 bitcoin today, and the next cut is about 76,800 blocks away.
A powerful enough quantum computer could forge Bitcoin signatures in theory. No such machine exists, and the distance between today's 105-qubit chips and the millions an attack would need is still vast. Here is what is real, what is years away, and what Bitcoin is already doing about it.
A breach of Keystone's website exposed customer names, shipping addresses and order details, the hardware wallet maker said. It confirmed the theft on October 23 and said recovery phrases and private keys were safe, but the leaked contact data still opens the door to phishing and worse.
The Indian exchange confirmed on October 25 that it lost 15.99 million USDT to an attack on a wallet system it retired after a 2025 hack. CoinDCX says it covered the loss. For three days before, its CEO and on-chain investigators argued over whether anything had been taken at all.
Britain's financial regulator opened two DeFi consultations on October 21, 2026, closing November 18, as it prepares to pull crypto inside its rules from October 2027. Coinbase warns the approach could box DeFi into a silo.
A dollar stablecoin never grows in value, so investing in one means earning a yield on the side. Here is where that yield comes from, across exchanges, DeFi and tokenized Treasuries, what it really pays, and the peg and platform risks the advertised rate leaves out.
Dubai's Virtual Assets Regulatory Authority has added Bybit to its public register with a full spot exchange license. Trading is not live yet, and the approval does not cover derivatives.

The halving cuts new supply in half, so the bitcoin price goes up after every one.
Our read: The supply half is true and mechanical: the subsidy went 6.25 to 3.125 on 20 April 2024 and goes to 1.5625 at block 1,050,000. The price half does not follow. There are only four halvings on record, each in a different macro environment, and the date has been calculable since 2009, so every participant knows it years ahead.
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.
Keystone says only website and order data leaked, and that customers' crypto, recovery phrases and private keys are safe.
Our read: The claim fits how the breach worked. It hit a web store database, not the offline device, so the keys that control the coins were never within reach. But it rests on Keystone's own account. There is no independent forensic report yet, and the company has not said how many customers were exposed or how the attacker got in.
CoinDCX says the loss was limited to retired wallet infrastructure, that it covered the 15.99 million USDT itself, and that customer funds were never at risk.
Our read: The company confirmed the loss on October 25 and says it absorbed it, and its live systems kept running. But it has not dated the failure or explained how the attacker got in, and on-chain investigator ZachXBT says a flagged address was still sweeping user deposits in 2026, which CoinDCX denies.

The objector count has more than doubled since BTC Newz reported the first opt-outs a week ago. Microsoft, Alphabet, Goldman Sachs and Wells Fargo are now among 22 US-listed firms blocking tokenized versions of their shares on the OKX and ICE venue. Trading has not started.
Andreessen Horowitz dropped the word crypto from its flagship blockchain fund on October 22, renaming it a16z Frontier and widening its mandate to AI and robotics. The firm says it will keep backing crypto startups, five months after calling its latest fund fully dedicated to them.
A minting bug on the Initia blockchain let an attacker create unbacked tokens and move about $2.7 million to Ethereum before the network was stopped. A day later the chain and its rollups stayed offline, with no restart date and no final loss figure.
Five Ethereum researchers filed a draft consensus design on October 21 that aims to cut the time a transaction takes to become final, from about 16 minutes to roughly four. The proposal, EIP-8453, is only seeking a number to enter the formal upgrade process.
A token on another chain backed one-for-one by bitcoin held elsewhere. Just over one per cent of all bitcoin is wrapped. The mechanics, the live supply figures, and what the WBTC custody fight showed about the risk.
Crypto sell-offs look chaotic, but most trace back to the same handful of causes. Leverage that unwinds fast, a shift in interest-rate bets, money leaving spot ETFs, and the mood across riskier assets. Here is how each one pushes prices lower, with real examples.
A crypto liquidation force-closes a leveraged bet when the trader's margin runs out. When enough of them hit at the same price, the selling feeds on itself. In October 2025 that loop erased more than $19 billion of positions in a single day.
Spot bitcoin ETFs in the US lost a net $773.43 million over two days as the price slipped below $82,000, cutting short a month that usually runs green. Analysts are watching the $81,000 to $82,000 band.
