Does Trezor need to be Plugged in to Send/Receive Payments?
Sending Payments
Unlike the Ledger Nano X that has Bluetooth connection and a 100 mAh battery(several hours of active usage, a few months when idle), Trezor hardware wallets needs to be connected and plugged into your computer for you to send out coins and tokens.
Receiving Payments
No, your device doesn’t need to be connected and plugged in to be able to receive payments. As long as you have a copy of your wallet address, people can send funds to your wallet as much as they want. The same applies to any other wallet, may it be a Ledger wallet, or a software wallet.
