Trezor's Chief Commercial Officer, Danny Sanders, has countered claims by blockchain investigator ZachXBT, who recently criticized crypto hardware wallets as "complete trash." ZachXBT suggested using a dedicated iPhone for storing funds and signing transactions instead. Sanders acknowledged that firmware updates can sometimes disrupt transactions and that the user experience can be "clunky." However, he refuted the notion that hardware wallets are ineffective, emphasizing that they remain the best self-custody method for average users, despite potential risks associated with iPhone's operating system and connectivity features.
