Ledger CTO has cautioned against Ethereum researcher Justin Drake's personal recommendation to migrate crypto funds to fresh addresses with hidden public keys. While Drake advocates for the move as a security enhancement, Ledger's technology chief argues that mass migration poses greater risks than the threat it aims to mitigate. The warning highlights concerns that widespread address transfers are more likely to result in fund losses through user error than protection from potential vulnerabilities. This disagreement underscores the tension between theoretical security improvements and practical implementation risks in cryptocurrency self-custody.
