❌ Cons of Using Trezor Wallet

1. No Mobile Support for iOS

While Trezor supports Android through USB or OTG connections, iOS users are out of luck — at least for now.

If you rely on mobile-only access or want on-the-go convenience from an iPhone or iPad, this is a clear limitation.

2. Lack of Native Bluetooth

Unlike competitors like the Ledger Nano X, Trezor does not support Bluetooth connectivity. While this decision favors security (wired connections are generally safer), it reduces flexibility for users who want wireless usage.

This is especially relevant for mobile crypto users or people who dislike cable clutter.

3. Plastic Build May Feel Less Premium

Trezor wallets are lightweight and made of plastic, which keeps them affordable — but they don’t feel as premium or durable as some metal-bodied competitors.

This might not affect functionality, but it could matter if you’re concerned about physical durability or simply prefer a more premium feel.

4. No Built-In Battery

Trezor devices need to be plugged into a computer or phone to work. There's no battery, which means no offline transaction signing without an external device.

For users who want full autonomy while traveling, this might be a drawback.

5. Higher Learning Curve for Advanced Features

While basic setup is easy, using features like coin control, hidden wallets, or passphrases can be overwhelming for non-technical users. Some of the security perks require time and understanding to use effectively.

If you're not confident managing advanced wallet options, there's a risk of misusing them — like losing access due to forgotten passphrases.
