Do you use an #Airgapped computer for managing your #seed phrases and #PSBT? I hope you do!
Here the steps:
- Get a old Lenovo Thinkpad X230
- Remove both the WiFi card and Bluetooth module
- Make the Ethernet port unusable (by damaging it)
- Encrypt the Hard Drive with a strong password
- Install Sparrow, Electrum or any similar Wallet
- Enjoy!
If your Airgapped computer gets stolen, it cannot be accessed as the hard drive is encrypted.
Your #bitcoin are safe!
