Cool, thanks for dropping some knowledge here--and I mean that sincerely.  Not being the most technical-minded person, I'm always impressed by the expertise of the community.

OP, my advice to you would be that if your Ledger is creating a lasting paranoia you'd best ditch that piece of shit wallet as fast as you can throw it into a meat grinder.  I've heard various things about the safety of the Nano S, but at this point I'm not sure what to believe (nor do I care since I'm not using one).  What is clear is that Ledger done told some lies, got caught, got egg in their face that still won't wash off, and justifiably lost a lot of trust that they worked hard to earn.  I've got some suspicions about what they're up to, but I've got no data to back those suspicions up so I won't even go there. 

But you ought to look into one of the HW wallets with open-source code, because that turned out to be the issue with Ledger and the backdoor they rammed up the buttholes of their customers.  At least with something like a BitBox, you can check the code if you're savvy enough.  Good luck.
