DCA is how a moderate wealth is formed.
Deep value bulk buy and hold is how typically a larger wealth is formed, it is just a fact, albeit this is more risky.
As usual, more risk, more reward.
Of course, you can do a combination of bulk buy and DCA.

Then, there is something that I call a VC approach-a relatively  small $ number for many very early/risky projects/stocks/whatever.
In this case, most will not pan out, but some will work great if you can choose them wisely. It's difficult to do and wait times could be more than a decade.
In this approach, you would have to intentionally limit your initial allocation and wait (could do small DCA) longer.

My main conundrum, though, are not with the investments themselves, but with cashing out. It seems that in most cases it is never a good time to cash out, but then, how to monetize holdings?
As we already know, typical means did not pan out in "our" area-witness Celsius, Blockfi, etc., etc.
Selling an asset with basically unlimited potential such as bitcoin seems stupid, although I did sell as needed here and there (not at tops or bottoms).
In a current environment it is simple: just have a large cash account and collect 4, soon 5% in interest, no need to sell anything, but once we drop to 2-3%, money would move toward more risky assets again.

TL;DR It is psychologically difficult to peel off money for consumption from assets such as bitcoin.
