How risky is it to use Bluetooth on a cold wallet?

Nice explanation! On top of that, Trezor Safe 7 protects Bluetooth communication with end-to-end encryption through our open-source security layer, Trezor Host Protocol. Even if Bluetooth itself has a vulnerability, an attacker cannot tamper with the encrypted communication between your hardware wallet and host applications.

💯 Trezor having that extra protecting layer (and open-source)

I personally dont understand why people use HWW with bluetooth even if the Bluetooth has no harm when there are other options without Bluetooth which is fully functioning. Not having attack surface is alway better than having more features.
