July ended with a striking contrast between crypto’s unshaken core and a volatile recovery in adjacent markets. Bitcoin held near $64,300 even after a sophisticated exploit drained 594 BTC — worth roughly $38 million — from old Coldcard hardware wallets in under 30 minutes, while equities and decentralized finance mounted sharp comebacks.
The attack, one of Friday’s biggest stories, targeted approximately 500 single-signature wallets created on Coldcard Mk3 devices with firmware version 4.0.1. A weakness in random number generation had made wallet seeds predictable, and funds that sat untouched for years were moved across just three blockchain blocks. Wallet maker Coinkite confirmed that newer Mk4, Q, and Mk5 devices are unaffected, and wallets protected by a BIP 39 passphrase face significantly lower risk. Yet Bitcoin’s price barely budged, briefly testing $65,300 in Asian trading before retreating to the familiar $64,300 range — a signal of deepening market indifference to isolated security shocks.
Meanwhile, on-chain activity pointed to a tentative DeFi revival. Active DeFi loans rose 7.2% in July to $22.2 billion, breaking a five‑month slide, with total value locked climbing from $68 billion to over $74.9 billion. Aave dominated with $11 billion in active loans and a 46.2% market share, while Morpho took a meaningful slice. The recovery was partly fueled by Ethereum’s 20.32% monthly gain, as ETH closed near $1,900, while Bitcoin added 9.03% over the same period. Uniswap extended its rally after expanding its fee switch across additional chains, and several low‑float tokens posted triple‑digit gains following fresh exchange listings.
The traditional‑digital divide was also on display. South Korea’s KOSPI index surged nearly 15% as chip giants Samsung Electronics and SK Hynix attracted renewed buying, and Taiwan Semiconductor posted strong gains, yet Bitcoin did not mirror the equity rebound as tightly as it did earlier this year. Instead, speculative capital chased memecoins and tokenized assets, keeping Solana’s stablecoin velocity elevated.
Underneath, liquidity constraints remained. The total stablecoin supply contracted 0.6% to about $312 billion, ETF inflows were weak, and treasury‑company BTC purchases froze. However, DEX trading volumes topped $169 billion, up over 10% on the week, and perpetual futures open interest continued to grow, reaching more than $15 billion. Aggressive leveraged positions became the norm, with former crypto whales even shifting to directional bets on equities such as SK Hynix. For now, Bitcoin’s resilience continues to anchor a market that is active but still searching for fresh capital.
