Trezor Wallet is the best physical wallet I’ve used, regarding security. Its build could’ve been better and could’ve been a bit more easy to access anytime we want. But, this is definitely not an average wallet. The whole idea of the Trezor wallet is to use it as a vault. When you have a lot of Bitcoins, you’ll want to store it in the safest place possible, and you store it in Trezor. You keep another wallet, which is online and easy to access. You do not store much here, but just enough to use some whenever you need and transfer to that wallet from Trezor if needed.
