Pros and cons
Coldcard
Pros
- Keys stay in self custody, and Microchip ATECC608 and Maxim DS28C36B handles the signing.
- Open source, so the firmware can be read rather than trusted.
- Connects over usb c and nfc, so a cable or a tap is enough.
Cons
- Coin support is 1, far below what the hardware wallet ranking usually covers at 345.
- Price of $219 to $319 sits at 110 on price out of 120 brands, with Trezor lower at $79.
- Support runs on email, help centre and community only, so a phone line is not part of the offer.
OneKey
Pros
- Custody sits with you: self custody keeps the balance and the keys off any operator's books, unlike bynex, whose custody is custodial.
- The signing chip is a EAL 6+ secure element, a stated security rating rather than a marketing line.
- Coverage of 30,000 coins is the strongest part of the offer, and the app lists self-custody among its features.
Cons
- Support runs on email, chat and help centre only, so written channels carry the whole help load.
- On price, OneKey ranks 103 of 120 brands, so the device is not the cheapest option on the page.
- The range $79 to $278 is wide, so the higher specification device costs far more than the entry model.
Who each suits
Coldcard
Who it suits
- A Bitcoin holder who keeps a single chain and wants signing done on hardware.
- Security-minded buyers who read the code, since Coldcard is open source and signs on Microchip ATECC608 and Maxim DS28C36B.
- Anyone comfortable guarding a seed phrase, since recovery rests on those words.
Who should look elsewhere
- Trezor buyers on a tighter budget, since Trezor sits at $79 against $219 to $319 here.
- Bit2Me users who want a mobile wallet for everyday use rather than a device that signs for you.
- bynex users who prefer custodial keys handled by the provider instead of kept in their own hands.
OneKey
Who it suits
- Long term holders who want their keys offline and their coin list long.
- Buyers who read code, since the firmware and app are open source.
- Shoppers comparing hardware who want the entry price to sit at $79.
Who should look elsewhere
- Bit2Me, whose wallet is mobile, if a phone suits you better than a device you own.
- bynex, where custody is custodial, if you would rather an operator held the keys.
- Trezor, if you would rather pay one fixed $79 than choose a model across $79 to $278.

Questions about each
Coldcard
What kind of wallet is Coldcard?+
Coldcard is a hardware wallet, so transactions are signed on a small device rather than on a phone screen. Keys are held in self custody, which means no provider holds them. It comes from Coinkite Inc., a company founded in 2012 and based in Canada.
What does a Coldcard cost, and how does that compare?+
Coldcard is a single purchase: $219 to $319 is the listed device price range. The median price across hardware wallets is €69.28, so Coldcard sits at the dearer end of that shelf. Trezor is lower at $79, and that gap shows up at the till.
OneKey
How much does a OneKey device cost?+
Devices are priced at $79 to $278, a range covering the entry model and the higher specification hardware in the same line. That figure is the cost of entry and there is no tier beyond it for extra accounts or extra services. It matters most for anyone planning to hold a wide set of coins, because coverage on the scale of 30,000 is where the money goes.
Who holds the crypto in a OneKey wallet?+
You do. The design runs on self custody, and the companion app lists self custody among its features. Nothing is deposited with an operator the way a custodial platform holds a balance, which is the main structural difference from an exchange account. The other side of that is that recovery is your job too, since nobody else holds a copy of the phrase.
