Bitcoin traded near $76,456 at 06:40 UTC on 3 November 2026 as traders cut risk before the US midterm vote. Spot Bitcoin ETFs lost $398.6 million the day before, and options markets priced in a sharper swing around the election.
A UTXO is an unspent piece of bitcoin your keys can spend. Bitcoin keeps no account balances, so your wallet adds up its UTXOs to show a total. Here is how the model works, why it sets your fee, and how it differs from Ethereum.
Market cap counts the tokens trading now. Fully diluted valuation prices in the whole supply, locked tokens included. The gap between the two numbers is where a lot of buyers get the risk wrong.
A flaw in the XRP Ledger let an account allowed only to burn tokens mint new ones instead. A fix backed by 33 of 35 validators can activate no earlier than November 4. There is no public sign the flaw was ever used.
A token approval lets a smart contract move your coins, and a single bad one can empty a wallet. Here is what approvals are, how drainers abuse them, and how to revoke access before you lose anything.
The Depository Trust Company switched on its Tokenization Service on October 28, letting 20 firms including JPMorgan and Citi mint on-chain versions of US stocks, ETFs and Treasuries. On-chain settlement and collateral use are still a 2027 plan.
Tether posted $1.5 billion in third-quarter profit and lifted its reserve buffer to $7.95 billion, a 30 October report attested by BDO showed. The figures cover one day, not the full audit the issuer promised in March.

Bitcoin's slide toward $76,000 is being driven mainly by nerves ahead of the US midterm elections.
Our read: Options data show traders paying up for protection around the vote, and one CIO says a Democratic win is not priced in. But QCP Capital ties the hedging more to the late-October Binance breach and weak sentiment, technology stocks fell the same week, and only three prior midterm cycles offer any pattern.
XRP Ledger developers have found a flaw that let a burn-only delegate mint new tokens, and say XRP's own 100 billion supply is unaffected while a fix awaits activation.
Our read: The fix ships in released software, the official docs carry the warning, and validator support sits at 33 of 35. But the amendment has not activated yet, its countdown already restarted once in October, and no one has confirmed whether any issuer delegated the permission or whether the flaw was ever used.
DTCC says its tokenization service brings US stocks and Treasuries into a regulated, blockchain-based framework and marks the start of a Web3 financial system.
Our read: The service is live with 20 named firms and rests on a December 2025 SEC no-action letter. But it is permissioned and limited, on-chain cash settlement and using the tokens as collateral are not switched on yet, and the official ownership record still sits with DTC. The IMF has also found tokenized stocks trade more volatile than the shares behind them.
Tether says USDT stays dependable, backed by growing reserves and steady profit, with a buffer that nearly doubled to $7.95 billion in the third quarter.
Our read: A BDO attestation supports the headline figures: $191.45 billion in assets, $183.50 billion in liabilities and $1.5 billion in Q3 profit as of 30 September 2026. But it is an ISAE 3000 attestation, not a full audit, it reflects a single date, and it does not disclose how many bitcoins Tether holds. The full audit announced in March has not appeared.

BTCPay Server, the free bitcoin payment tool, told operators to switch off their servers on November 1 after reports that attackers swept funds from internet-connected hot wallets. The project says only older versions were hit, and has not named a loss figure.
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.
Tether posted $1.5 billion in third-quarter profit and lifted its reserve buffer to $7.95 billion, a 30 October report attested by BDO showed. The figures cover one day, not the full audit the issuer promised in March.
Brazil's largest crypto exchange froze deposits and withdrawals on 2 November after attackers moved funds from its wallets. Security firm Hypernative estimated more than $40 million left across at least 10 chains. Mercado Bitcoin says it contained the breach and that no customer funds were harmed.
Anchorpoint, a Standard Chartered-backed issuer licensed in Hong Kong, said it will work with the Solana Foundation to mint and redeem its HKDAP stablecoin on the network. No launch date has been set, and the token is still limited to institutional users.
A flaw in the XRP Ledger let an account allowed only to burn tokens mint new ones instead. A fix backed by 33 of 35 validators can activate no earlier than November 4. There is no public sign the flaw was ever used.
Attackers hijacked the domains of about a dozen DeFi sites registered with Name.com late on October 30, pointing visitors to fake pages that drained their wallets. No smart contract was breached. Early estimates of the theft run from about $138,000 to $202,386.
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.
