Well, let's say that you came to bitcoin in 2018 (so 5 years ago)---
and between 2018 and now you were able to accumulate 4.5 BTC for an average price of around $10,000.... so you could have various price points in which you sell those BTC in 2023 (or maybe at some future date), and if you sell all of your BTC, you may well end up struggling to figure out how to get them back. Whether you can buy back your BTC at the price that you sold them might be another question... and whether you can invest the value of those sold BTC into something that is equal to or better than BTC is still another question that you will face with levels of uncertainty.
When it comes to taking profits along the DCA line, one needs to apply a lot of constraints and shouldn't over sold at any point no matter what the price may be or the profits merging on the Bitcoin, since selling Bitcoin at every possible opportunity only lead to loss of your bitcoin holding, because bitcoin is more fun when it is held for the long term.
There is risk associated with taking profits at every market advantage which is the possible inability to get those bitcoin back at the same value you first buy the bitcoin, and since bitcoin accumulation is a journey, one needs to apply the same time principle in both the buying and selling point without a rush in both.
