What to compare in crypto wallets
Compare the fee, the custody model and the backup method. A hardware wallet such as Trezor costs $79 up front, while a card account at Bit2Me runs on a debit card instead. On custody, Trezor keeps keys in self-custody with a seed or Shamir backup, and its secure element carries a EAL6+ rating. Derivatives are not offered and the software is open source.
