According to this chart the past 2 halvings have been followed soon after by an insignificant dip. Insignificant long term but at the time felt like a letdown due to the hope that the price would rise right after the halving. There was a jump right after the first halving due to the scare that the halving would cause the end of Bitcoin due to miners stopping mining. When they didn't stop the price jumped a little. Before easing back down. I remember selling about 400 bitcoins after that quick jump to $12 (all the bitcoins I owned).
400 BTC is a good amount of bitcoin to aspire to, and even to maintain as a reasonable ongoing amount, even though they were only worth about $4,800 at that particular 1st halvening time. Hopefully, you were able to buy back some or all of them for at or below $12. What you did after that might be a different story.
I suppose that the longer that any of us have been in the bitcoin accumulation world, there is an amount of bitcoin that we can point to that we had, at one time that we no longer have or are able to get, but some of that would be somewhat natural and reasonable to maybe have difficulties maintaining a certain quantity of BTC and retaining some desire and practice of shaving off some dollar profits at various points in time.
Someone in earlier accumulation phases (or later entrants into BTC) may not have reached their peak bitcoin points, yet.
Personally, I have a point that I can point to, and I doubt that I will ever get even close to having that many BTC again, but that is o.k.. I do not live in the past, and I am more than happy with my current accumulation level and also my various future projection that involve both shaving off profits from time to time and also possible accumulation, too (but at the same time only an outline so some uncertainties regarding how the specifics of those projections are going to play out).
