You are lacking in imagination if you believe that overaccumulation cannot be achieved.
Let's say that there is a person who was in his mid 30s in 2016, and he started accumulating bitcoin in 2016, so now he is in his mid 40s. When he started investing in bitcoin he had been earning around $30k per year, and he had been investing in various other assets at a rate of about 20% of his income (about $120 per week), so his total investment time had been about 10 years, so he had an investment portfolio of about $100k. In 2016 he decided to continue to put $120 per week into bitcoin, yet he also decided to put 40% of his already existing investment portfolio into bitcoin (which would have had been $40k). His goal was to get to having a passive income of $80k.
So his initial purchase of $40k worth of bitcoin got him right around 61 bitcoin (since he got them around $650 each).
The power of constant investments, such as DCA strategies, is really impressive.
Since I started working, almost 20 years ago, I tried to save everything I could, I lived in a very frugal way for years.
THen I discovered this forum and started accumulating $20, $30 usd per week in bitcoin. After a few years I reached $100 per week, and then $300 per week.
All that small amounts of money from the forum allowed me to accumulate much more bitcoin than I would have ever imagined.
Ofc the price of bitcoin skyrocketed and it helped a lot. But it may skyrocket again to 200k levels in a few years.
For sure, we might consider that we are doing all that we can do in regards to our DCA practices, yet with the passage of time, we also might identify other sources of funds and/or even ways that we might cut some of our expenses in order to increase our discretionary income and thereby increase the amount that we can put into bitcoin.
I would hardly consider $200k-ish as skyrocketing, even if the number comes off as a large amount, including that bitcoin's market cap would end up going from around $2 trillion to $4 trillion, so surely bitcoin would be getting bigger and bigger and surely on a correct path in regards to ongoing growth.
Another thing about the various price rises, there surely can be dilemmas for anyone accumulating bitcoin since any of us who consider that we are still accumulating bitcoin and/or being in our early bitcoin accumulation stages, there is not necessarily advantages regarding having the BTC price to continue to be going up.. so many of us likely realize that we would have had been way better off to have been accumulating bitcoin between about mid-2022 to late 2023 as compared with how many BTC we are able to accumulate today with the passage of only 2-3 years worth of time, there is a decently large decrease in how much bitcoin we are able to accumulate with similar amounts of cash...or even if we might have had tripled our DCA amounts per week, we are still stuck with accumulating way less bitcoin with those weekly bitcoin purchases.
