Do you keep your private keys on hardware wallets, or are they stored on your hard drive? My wallet files are watch only, but with the master fingerprints so that I can use them to sign from an air gapped device.
I use a combination.
I have small amounts of coins on hot wallets on both mobile and desktop. I used to use a number of different hardware wallets, but given the number of hardware wallets over the last few years that have been shown to have critical vulnerabilities, horrendous privacy features such as implementing KYC exchanges or credit cards, horrendous security features such as online back up, and so on, I've pretty much abandoned them all. The vast majority of my coins are stored in permanently airgapped devices using full disk encryption.
