Questions about each
BitBox02
How much does a BitBox02 cost compared with other hardware wallets?+
It is a one-time device purchase, not a subscription. Across hardware wallets on HodlCue the median price is €69.28, with the middle of the group starting around €52.24. Coins stay in self-custody, so the device is the main outlay you make.
Who holds the coins in a BitBox02?+
You do. Custody is self custody, so the keys never sit with Shift Crypto AG, the company behind the device, which is based in Switzerland and founded in 2015. The firmware is open source, and key handling happens on an ATECC608B secure element inside the device.
CoolWallet
How much does a CoolWallet cost?+
CoolWallet is a hardware wallet, so the cost is the device price of $39 to $149. There is no account or monthly charge attached to holding coins on it, and the keys stay with you. Expect to pay for the hardware once rather than per year.
Does CoolWallet hold my coins for me?+
No, custody is self custody, and self-custody also appears in the listed features under self custody. You hold the wallet and the seed phrase, so losing either one means losing access. That is the trade for keeping control.
