Does Ledger need to be Plugged in to Send/Receive Payments?
If you have the Ledger Nano S or a Nano S Plus, then your device needs to be connected and plugged into your computer to be able to send transactions.
Of course, you will also be needing internet connectivity. May it be through WiFi or your mobile data.
On the other hand, if you have the Ledger Nano X or the Ledger Stax which has Bluetooth connectivity and a battery that can last a few hours, you can send transactions simply by connecting your device to your mobile phone via Bluetooth.
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 hardware wallet, a software wallet, or an exchange wallet.
Exchanges change their wallet deposit addresses from time to time regardless of what cryptocurrency. Always make sure that you’re receiving funds on your exchange wallet with the correct and updated wallet address.
