Klippsten estimated that quantum computers capable of compromising Bitcoin's cryptography are at least a decade away, possibly longer. Mercado Bitcoin suspended deposits and withdrawals on Monday after a security incident, with researchers estimating that more than $46 million had moved out of the exchange's wallets. Klippsten warned cryptocurrency companies against protecting customer assets with hastily developed software.

Polymarket and Kalshi markets favor Democrats winning both congressional chambers in the 2026 U.S. midterm elections, with probabilities of 78% and 74%, respectively. Trading volume exceeds $58 million in the relevant Polymarket market and $100 million in the corresponding Kalshi contracts. Both platforms also favor Democratic candidates in individual Senate contests in Texas, Maine and Michigan. Kalshi CEO Tarek Mansour said election-related betting volume already exceeds $1.4 billion this cycle. However, Kalshi previously failed to predict Luiz Inacio Lula da Silva's victory in Brazil's presidential runoff.

North Korea denied responsibility for the $6.3 billion Binance hack and rejected the FBI investigation as fabricated. Yonhap News Agency reported on Tuesday that Kim Yo-jong called the investigation a "political provocation." The FBI attributed the attack to the North Korean group TraderTraitor on October 31 and urged crypto firms to reject transactions involving linked wallets. Binance resumed crypto withdrawals after saying reserves had covered about 95% of customer losses. President Donald Trump said on Saturday that the United States did not yet know whether North Korea was responsible.

Ethereum co-founder Vitalik Buterin said he used kohaku-cli, a command-line wallet, for many payments involving privacy protocols. Buterin's October 31 essay also described a separate AI-written tool for updating IPFS content hashes on ENS. Kohaku-cli's documentation warns that the application is unaudited and that mainnet use can result in catastrophic fund loss. Keeping an application locally allows users to control software updates, but dependencies and signing permissions remain separate risks. A prepared Railgun unshield operation can already carry a signature even when the wallet has not broadcast the operation.

Berkeley Law lecturer Hermine Wong argues that voters should not confuse support for crypto technology with loyalty to the companies financing crypto politics. Crypto super PACs have committed $63 million to Ohio's Senate race to keep Sherrod Brown out of the Senate. Wong argues that Fairshake's spending does not consistently reflect legislative records or Stand with Crypto's candidate grades. Fairshake's spokesperson says the organization supports candidates from both parties who favor crypto and American innovation. Wong concludes that the industry's political spending succeeds only if voters support the industry's chosen candidates.

XRP could suffer cascading liquidations if the price falls below $1.24, potentially deepening losses before a sustained recovery. Crypto analyst Cryptoinsightuk warned that rising leverage alongside stagnant prices could force long positions into liquidation. Chart analyst Ali Martinez said unusually narrow Bollinger Bands signal an imminent increase in volatility, but not the direction. Martinez considers $1.23 to $1.27 a range in which traders should avoid trading. Ripple CEO Brad Garlinghouse predicted that XRP will become the institutional standard for cryptocurrency payments within five years, despite short-term volatility.

Blockchain investigator ZachXBT said an unidentified European Union entity may have lost more than $106 million from accounts across several cryptocurrency exchanges on Sunday. ZachXBT said suspected stolen funds were withdrawn as USDC and USDT and subsequently moved across cryptocurrencies and blockchains. Separately, blockchain monitoring account Onchain Lens said a wallet associated with the Solana arbitrage bot King may have lost about $786,000 on Monday. Onchain Lens said the transfers strongly suggested a possible wallet compromise, but King's operator has not confirmed a compromise.

The suspected theft follows the $6.4 billion Binance hack, which the FBI attributed to North Korea's TraderTraitor hacking group. Whether any funds from the EU case have been frozen remains unclear.
