In the transactions log, I can see a transaction that seems to take the funds from my wallet and send it to a different address (change address I assume?)
The transaction log does not display outputs funding change addresses. It is likely what you are seeing is an actual transaction moving your funds.
Here is the info in my transaction log:
Sender
Non-Standard: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy
Script Type
Sig+PubKey33
and just underneath that is another transaction
Non-Standard: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy
Script Type
Sig+PubKey65
After these two are transaction that I recognize
and lastly at the bottom of the log is
Non-Standard: 3J98t1WpEZ73CNmQviecrnyiWrnqRhWNLy
Script Type
Sig+PubKey33
In this case we are not talking about a huge sum, but as I am considering using bitcoin more in the future I need to understand how it could be that my funds were taken/moved outside of my wallet.
I am using an encrypted OS, I encrypted my wallet using dice-ware passwords (7 random words). Apparently this is not enough. What else do I need to be doing to protect my funds in future?
