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.
Yeah, I've been sitting through it and now I'm in too deep to turn back.
I can handle a bubble to 1000 or 3000 without losing my head. Part of me will just be thinking "Finally!"
But if it goes to $10,000 to $100,000 within the next 5-6 years, I can't see myself staying cool. Even after all the long hours playing with models and various assumptions to convince myself that it's possible.
