Crypto hardware wallet comparison CoolWallet Pro vs KeepKey
Our impressions
CoolWallet Pro
KeepKey
- Has a great community and (d)app ecosystem
- Outdated microUSB port
- Needs constant USB connection
The product has a nice build quality and finish, a solid (d)app ecosystem, and a great community. The product launched in 2015 and it shows its age, compared to newer hardware wallet products. Most notably it has no secure element, a microUSB port, and limits itself to a single button for on-device input.
That being said, we would still prefer it over any software wallet, though.
