I had written out a long reply but while I was finishing the balance started adding back up until everything was square. Must have been a sync problem. Thank you so much for taking the time to help me out!
I understand your fear. Glad that everything worked out.
Since you are familiar with Tails what you could do is track the addresses that you own without the need to type in the seed on a Windows computer.
For example:
- running off of
https://bitkey.io/ live cd lets you run a page like
https://iancoleman.io/bip39/ from a USB stick (that you can unplug) in a Chromium browser. From that offline computer you can display public addresses connected to your seed and scan them with any mobile device.
That way there is no risk to exposing your seed and no BTC-gone-induced heart attacks.
