It's been said a million times by the veterans, but it bears repeating: the mistake you'll make is selling too early. I've done it multiple times, even after learning that it was a bad thing to do. I doubt your "hodl until I die" plan will work when emotion takes over.
The last year and a half have been a fine trial by fire for people who've sat through it all. I'm sure they've felt the full spectrum of emotions. If you've lived through this then I think you're probably pretty hardened to future swings. If you're still around now you're likely to be in it for the long haul.
