Use of Hot Wallet not Associated with Maker of Cold Wallet

Hey all,

Recently started using a Passport for my cold storage with the associate Envoy hot wallet.

More recently I saw someone comment that users should NOT be using a hot and cold wallet associated with the same business for coin safety reasons.

I tend to be overly careful, so am considering just switching to Sparrow, or something similar, but can anybody here speak to that concern? Is it overly paranoid? Especially with something completely airgapped like Envoy’s Pasaport wallet?

Thanks in advance! Stay humble, stack sats!
