Nearly half of retail cryptocurrency investors see themselves, rather than external hackers, as the greatest threat to their digital assets, according to a new survey by U.S. exchange Kraken. Polling 800 American crypto holders, the study found 48% were more concerned about losing funds through personal error—such as mismanaging private keys—than via a coordinated cyberattack. The findings echo a separate study released by cybersecurity firm CSC, which reported that an overwhelming majority of Chief Information Security Officers anticipate a significant increase in cyberattacks over the next three years. Together, the surveys highlight a dual challenge for the security sector: rising external threats and persistent vulnerabilities created by user behavior.
