Questions about each
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.
Keystone
What does a Keystone hardware wallet cost?+
The device is priced at $149, a one off purchase. As a hardware wallet it keeps working offline, with no subscription attached to holding. A Trezor device sits at $79, so Keystone asks for more at the checkout.
Who holds the coins on Keystone?+
Custody is self custody, so the keys stay with the holder and never sit with a company. If the device is lost, recovery depends on the backup, and the options listed are seed and shamir. Nothing sits with a third party to claim back.
