I have a tendency to take some profits every time bitcoin reaches a new all time high, so that's what I did. Maybe not exactly on the day it happened, but sometime in the days around it.
That being said, I always plan to sell much more bitcoin than I actually end up selling, and this strategy has worked pretty good so far so there is no reason to change it.
Did it work for you?
I'm still one step away from being my head against the wall for not selling at least half of the coins at over $100k, with safe investments like bonds, I would be right now up $43k for each coin over two years, and this not taking the ATH into consideration, just dumping it at $100k right after it crossed.
Just thinking of it pisses me off!
That aside, I'm too lazy to do the math but have we actually been through these situations before, where the price would be lower that it was 5 years ago?
If you are getting sad about this, that means you are carrying a bigger btc position than you should have.
Perma-bulls get happy when the price crashes but being a perma-bull on btc doesn't mean they shouldn't be carrying other positions, especially the cash producing ones and cash itself.
I mean one could be a super btc bull but carry only 5% btc in his total wealth. 5% of a 10m USD portfolio is 500k USD. That's no joke and he would be actually reckless to have all 10m USD in btc if you ask me and that's why this imaginary investor i just invented is not thinking about banging his head to the wall but you do. He can just wait it out, add to his btc position or even exit his position completely even now if he desires it.
As you see, feelings can change, it all depends on the context really.
