_KeepKey is a well-known hardware wallet. Is it really good and reliable? KeepKey is a hardware wallet that has a clean and modern design. The wallet is easy to use, offers unique security measures, and customer-friendly prices. The wallet itself can be easily managed from your mobile device. However, the main problem is that it only supports 40 cryptocurrencies. This is a very cool option for storing coins. Overall, I was satisfied with the reliability and stability. KeepKey is a hardware wallet that comes with some great security features. Since it is a cold wallet and your assets are stored offline, this is one of the safest vaults for your assets.
