Bitcoin Stays Flat as Kospi Soars 17%

Bitcoin spent much of July moving in tandem with the semiconductor trade, making South Korea’s Kospi a closely watched gauge of risk appetite. That relationship weakened as volatility intensified across technology shares. Crypto’s failure to join one of the year’s sharpest equity rebounds suggests investors were not broadly rotating back into digital assets, while the muted response to a major wallet breach further underscored the market’s lack of momentum.

On July 31, 2026, the Kospi surged as much as a record 17%, with Samsung and SK Hynix each climbing more than 23%. Bitcoin held near $64,300 after briefly reaching $65,300 in Asian trading and remained down 2% for the week. Between 01:31 and 01:56 UTC, an attacker exploited a Coldcard key-generation flaw to drain about 594 bitcoin, worth roughly $38 million, from around 500 wallets. Coinkite said its Mk4, Q and Mk5 devices appeared unaffected, and the theft had little visible impact on prices.
