You can theorize about the process, yet it seems to me that getting through a whole cycle of bitcoin accumulation will likely help you to have a bit of a track record, and even help you to figure out how well you might have been able to follow your original plan or if you might have had tweaked your plans at various points along the way.
In the last few years I have come to understand that anyone who is persistently accumulating bitcoin at a similar rate for 4 years is likely going to have average BTC prices that are right around the 200-WMA, and surely if your accumulation period is even longer then your average cost per BTC will be further and further below the 200-WMA.. which historically has tended to be a good place to be, especially if you can get your average cost per BTC to be more than 35% below the 200-WMA while still building a decently large BTC stash in the process.
Don't get me wrong, since I am not advocating that it is better to have a low cost of BTC rather than accumulating a decently large bitcoin stash, and as an investment, it can take a bit of time to have both the low cost per BTC and a decently large BTC stash.
That actually makes a lot of sense. Going through a full Bitcoin cycle gives you a better picture of how well your strategys should holds up in real conditions, not just in theory. It also shows whether you stuck to your plan or had to adjust based on what the market threw at you.
I have also noticed how powerful DCA can be over time. Staying consistent over four years tends to bring your average cost close to the 200week moving average, which historically is a solid position to be in. And if you keep going beyond that, your average can end up even further below that level, which gives a stronger base for future gains.
Of course the main goal is to build a solid stack without over extending yourself and if that stack ends up being built at a strong average price, that is even better. But finding that balance between growing your holdings and not chasing the lowest price is something that only time and discipline can really help you manage..
