Why Arbitrum is up 1.1% in the last hour

Analysis

Arbitrum (ARB) rose about 1.1% over the past hour despite fresh security headlines, as traders appeared to digest reports of a “massive $290 million hack” affecting Ethereum and Arbitrum rather than extending immediate sell pressure. U.Today’s coverage of the exploit likely drove short-term volatility, but the modest uptick suggests the market impact was limited in this window.
