Wow, I admire your dedication to travel: I must admit I'm planning to avoid any near term air travel if possible due to covid-19. I know it's probably excessive concern, but I often catch something from plane travel in normal times...
As far as the post goes, I was really hoping it was at the general reader level, instead of just targeting crypto people. If there were some points that weren't clear, I'd be happy to add more words, if you could point me in the right direction. It is more than possible I made too many assumptions about the reader's background, and if so, I'd like to repair that lack.
