Bitcoin holders are moving funds back to centralized exchanges after a Coldcard hardware wallet vulnerability raised fresh concerns about self custody. On chain data shows smaller transfers and exchange deposits spiking in a pattern that contrasts sharply with the response to FTX’s collapse.

Crypto platforms are extending perpetual futures beyond digital assets and into stocks, indexes and commodities, creating round-the-clock exposure to traditional markets. The shift is drawing institutions seeking lower-friction hedging and retail traders looking for access, while questions remain over custody, investor protections and decentralized venues.

A Coldcard firmware vulnerability tied to weak software-based randomness has been linked to three waves of bitcoin sweeps across thousands of addresses. The latest activity is targeting smaller balances and using more complex onchain collection patterns.

A Bank of Italy mystery-shopping exercise found that USDC remittances were not systematically cheaper than traditional money transfer options across international corridors. The findings point to exchange fees, foreign exchange spreads and local banking charges as the main costs, rather than blockchain transaction fees.

Tokenized stock and ETF trading climbed to a record $11.3 billion in July, rising 288% as demand concentrated heavily in Binance’s QQQB token. Excluding QQQB, tokenized-equity volume was roughly $2.03 billion, about 30% below June’s implied total.

The SEC has frozen Nasdaq’s approval to list cash-settled bitcoin index options under the QBTC ticker while it reviews a challenge from CME Group. CME argues that bitcoin’s commodity status places options tied to its value under CFTC jurisdiction rather than SEC authority.

Solana Foundation CISO Michael Coates says crypto’s next major security challenge is shifting from code exploits toward AI-powered social engineering, fake identities and compromised credentials. The foundation is also evaluating post-quantum cryptography as blockchain networks prepare for longer-term risks from quantum computing.

Binance founder Changpeng Zhao has urged crypto holders to spread funds across multiple wallets after a major Coldcard hardware wallet exploit. The incident exposed a long-running firmware flaw that allowed an attacker to reconstruct private keys offline and drain bitcoin from affected addresses.

More than 1,000 bitcoin was drained from 1,196 Coldcard wallets in a 41-minute window on July 30 after weak seed generation made private keys computationally searchable. Security researchers warn the episode challenges a core assumption of cold storage: that offline keys are not just unreachable, but effectively unguessable.

The XRP Ledger’s expected xrpld 3.3.0 release will ask validators to review five proposed amendments, including revised versions of Batch and Permission Delegation. Both features were previously pulled after researchers identified flaws that could have enabled unauthorized transactions or fee draining.

Bitcoin is on track to end July with a gain of about 7.5%, even after sliding below $63,000 and facing pressure from rate-hike fears, higher bond yields, an AI-linked sell-off and a Coldcard security incident. Market participants say reduced leverage helped limit forced selling, while U.S. jobs data, Federal Reserve expectations and spot bitcoin ETF flows may shape the next move.

Perpetual futures have become the core venue for many crypto traders because they offer deep liquidity, low fees and strong margin efficiency. Yet traders warn that floating funding rates can turn even a well-timed position into a costly trade if held too long.

Tether reported $1.5 billion in net operating profit for the second quarter of 2026, supported by returns from U.S. Treasury and repurchase agreement holdings. The USDT issuer also expanded its gold and bitcoin reserves, even as the value of those holdings declined alongside weaker gold and bitcoin prices used in its attestation.

A firmware flaw in Coinkite’s Coldcard hardware wallet has been linked to the theft of nearly 600 bitcoin, worth roughly $38 million so far. The incident is forcing Bitcoin investors to reconsider the trade-offs between self-custody, professional custodians and spot Bitcoin ETFs.

A Dubai-based crypto exchange has become the focus of allegations involving a $4 billion Iranian sanctions-evasion network tied to illegal gambling platforms and sanctioned entities. Investigators say funds connected to Shelbit moved through major global crypto venues, while Binance says Shelbit never held an account on its platform and that it froze relevant accounts after review.

Coinbase’s second-quarter results fell short as weak crypto prices and subdued trading volumes pressured revenue and adjusted EBITDA. Analysts broadly pointed to market conditions rather than execution, while debating when trading activity can recover.

New York has sued Kalshi, alleging the prediction-market platform offers sports and event wagers without a gaming license. The state is seeking to bar the company from operating what officials describe as an unlicensed gambling business, while pursuing restitution, damages and civil penalties.

Bitcoin and ether slipped into the end of July, diverging from gains across Asian equities and U.S. index futures. The broader crypto market remained on track for its strongest monthly advance in a year, but derivatives positioning showed traders leaning cautious.

Quantum Solutions sold 1,000 ETH for $1.9 million and expanded its board-approved disposal ceiling as it seeks funding for an AI data center business. Hyperscale Data separately monetized about 100 BTC and opened a bitcoin-backed credit facility for its Michigan AI campus.

A flaw in Coldcard firmware key generation enabled an attacker to drain roughly 594 bitcoin, worth about $38 million, from around 500 single-signature wallets. Coinkite has warned users who created seeds on certain Mk3 devices, while early analysis suggests Mk4, Q and Mk5 devices are not affected so far.

Bitcoin and major cryptocurrencies were little changed even as South Korean equities staged a dramatic rebound led by chipmakers. A Coldcard wallet security flaw and a sharp rotation in Asian stocks did little to move the crypto tape.

Coinbase shares fell in after-hours trading after the crypto platform reported second-quarter revenue below Wall Street expectations. Weak digital asset trading, lower transaction revenue and pressure on subscription and services revenue kept investor attention on the company’s push beyond spot trading fees.

Strategy reported a second quarter net loss of $8.2 billion as bitcoin weakness triggered a major unrealized markdown on its holdings. The company also highlighted a $3.75 billion U.S. dollar reserve, selective bitcoin sales and plans to develop its Digital Credit business.
