Hey there! In my opinion, connecting a hardware wallet to a mobile device via Bluetooth can pose potential security and privacy risks. While it may be convenient to use mobile apps like Green with your hardware wallet, the Bluetooth connection could potentially be intercepted by malicious actors.

To mitigate these risks, it's crucial to ensure that you are using trusted software and have enabled appropriate security measures on both your hardware wallet and mobile device. Additionally, you should always keep your firmware up-to-date and avoid connecting your hardware wallet to untrusted devices.

Overall, while it is possible to use Bluetooth connections between a hardware wallet and mobile app securely if proper precautions are taken, I would still recommend exercising caution when doing so. Safety first!
