It's the butterfly effect , you can't just play these stupid hypotheticals and assume the best possible outcome.
We all had these situations again and again.
It does not matter, each timeline is unique, maybe someone who bought in 2010 would have lost it on Mt. Gox, etc., etc.
It's like you could have bought Apple or Microsoft for pennies. Yeah, you could have, but the chances that you would have kept that stock for 20-30 years are very very low.
S. Ammous says that most of those with a lot of btc will
inevitably sell at some point and I generally agree, to a point (maybe not everything).
That point is different for each one, but, let's say at a price higher by one or two orders of magnitude, who would not at least sell a chunk that establishes a nice lifestyle for a few decades? Would you grimly hodl that btc or would you rather enjoy yourself a bit (vacations, houses, dining, entertainment, etc)? Only very few may be able to resist.
In fact, i think that a large portion of current hodlers would have sold a large chunk if btc levitated at $20K for a few months. It just went up and down a bit too fast.
