So even if they might say that they are ready for either up or down prices, they might end up not really being prepared because they ended up over-investing in light of their own mental preparedness.
Halving 2024 I released all Bitcoin holdings that had been DCA for 4 years (maybe it's too early to release it but as a small retailer the economic situation is not always friendly), full of twists and turns and indeed as you said it is not easy to win mentally from the fluctuating price situation when the financial condition is getting thinner but I have gone through all that. From the sales I managed to build my dream house.
Now facing the next 4 years I will start DCA again with full preparation from before, with strategies and all the shortcomings that have been evaluated.
Well I will say that the mistake has been made already. The best approach would have been to sell part of the bitcoin you have held for the past 4 years, instead of selling all at once and having no bitcoin at your possession. You will agree with me that you can't get bitcoin at the price you got it 4 years ago. And for you to get that amount of bitcoin in today's market reality you find out you are going to spend more money than what you even sold it for. The best approach was to sell the profit you got from the investment you made in that 4 years of holding, since you had need to take from your investment, after your successful holding of a circle. You should have kept part that was equivalent to your capital invested. A good famer don't eat up his seed, and start looking for where to get seed in the next planting season. He always reserve his seeds.
