You might want to move this thread to Beginners & Help, since it's your first post and contains a number of subjects that don't fit neatly into Bitcoin Discussion. You can do that yourself or perhaps one of the mods will if they see fit. You might get answers to your questions there; this section is filled with garbage posters who just want to post for the sake of their campaigns, and in the end you probably won't have any good advice come your way.
And by the way, bitcoin hitting $1M would be increasing by 10x (obviously), and normally I'd be the first to say "no way!". But after seeing the market heat up the way it has over the past decade, I wouldn't rule that out at all. Hopefully it'll get there slowly and not in the form of a bubble that's going to pop....but who knows.
