Buying Bitcoin is legal for individuals across the UAE, and Dubai's VARA now licenses the platforms that sell it. This guide covers choosing a licensed exchange, passing identity checks, paying in dirhams, fees to watch, and keeping your coins safe.
US spot bitcoin ETFs recorded $643 million in net redemptions on 30 October 2026, the biggest single-day outflow since June, as bitcoin fell toward $77,000 and ether funds extended a fifth day of losses.
A small Nasdaq-listed firm, Next Technology Holding, has cleared a sale or pledge of about 5,833 bitcoin worth roughly $452 million, citing the record Binance hack and quantum computing risk. No coins have moved, and analysts see a liquidity move more than a security one.
A major UK asset manager has moved a slice of a £22 billion sterling money market fund onto a public blockchain. Aviva Investors seeded the new tokenized share class with £50 million, and the fund underneath still runs the old way.
South Korea's presidential office is leaning toward delaying the country's 22% crypto gains tax for a fourth time, pushing the start from January 2027 to 2029. No decision is final, and the tax stays law until the National Assembly changes it.
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 security breach at Binance triggered institutions to pull hundreds of millions from bitcoin ETFs in a single day.
Our read: The $643 million outflow is confirmed by two data providers, Farside and SoSoValue, and is the biggest since June. The link to the breach is inferred from timing, not stated by any issuer or regulator, and the same funds had taken in $440.8 million over the prior four days.
Next Technology says it may sell or pledge up to 5,833 bitcoin to cut custody risk from exchange hacks and the long-run threat of quantum computing.
Our read: The Binance hack is real, verified and large, but no sale has happened, and the firm has named no buyer, lender, price or timetable. Its bitcoin is worth about sixty times the whole company and none of it sat on Binance, which points to a liquidity need more than a quantum fear.
Tokenizing fund shares on the XRP Ledger makes the fund more efficient and improves outcomes for clients.
Our read: A real launch by a major manager, with named custodians and £50 million committed. But the £50 million is Aviva's own seed, the firms have not disclosed any outside take-up, and the underlying fund still operates exactly as before, so the efficiency gains are promised rather than measured.
A fourth delay is needed because South Korea cannot collect the tax fairly until global data-sharing, including with the United States, is in place.
Our read: The overseas-data gap is real, and the OECD framework does lag for US accounts until later this decade. But the tax has been law since 2020, the delay is not yet official, and no one has published what a two-year postponement would cost in revenue or how ready the collection system actually is.

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.
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.
