Mostly agree. There's too many people "saying" when the right strategy with bitcoin is "doing" and then "not doing anything". It is so counter-intuitive and so against what most of us have been told - "you need to work hard to succeed", "you need to be active", "you need to stay on top"...
An bitcoin is just about not doing anything - well, not exactly - it is about learning and then having the mental strength to do absolutely nothing (AKA hodling).
Yeah, but we have to accumulate first and get to a point that we have enough bitcoin before holding becomes really meaningful.
Sure, another thing is that we can start out with a small amount and then just hold until that small amount becomes a large amount, yet I personally believe that a better strategy is to continue to buy, at least in our earlier years, perhaps a whole cycle or two, and then once we spent a cycle or two accumulating, then after that we can mostly hold and perhaps even spend from our bitcoin from time to time without worrying about when we are spending or how much we are spending.
Perhaps an exception to the idea of continuing to buy applies to those who are able to front load their bitcoin investment, yet my presumption is that an overwhelming majority of normal people are not going to either be in a position that they are able to front load their investment into bitcoin, and even if they might be able to front load their investment into bitcoin, they are mostly not going to be willing to, which is another justification for ongoing buying through DCA rather than just buying and sitting on our hands.
Ongoing buying also reinforces the idea and is likely superior to not doing anything, even though I would still agree that just holding also works, but it is not as good as ongoing buying, even though ongoing buying may well end up increasing our costs per BTC, but we will end up with way more BTC to give us more options and cause us to reach overaccumulation status faster. ONce we are at overaccumulation status, then we surely have more options to buy or sell and perhaps try to stay in overaccumualtion status by not selling to many at any given time.
On the DCA thing... it seems that it is now frequently mentioned, but this exists since forever. It is usually called temporal diversification and you can do it also in the stock market. Diversification can be buying several assets to protect yourself agains... perhaps your own ignorace, imperfect information or simple bad luck.
Temporal diversification (such as DCA or other automated investing systems) is to protect you from your ignorance about when is the optimal moment to buy - clearly my case and honestly the case of most. I would advise this to any normie (I am perhaps a normie to some extent).
DCA is only deferring the buying of bitcoin when it is done when a person already has a lump sum of money available.
Many times DCA is a means to buy as much bitcoin as we are able to buy as the money comes in.. We do not have the money in advance or to use our income to buy bitcoin prior to it coming in, and so therefore many of us will be forced into DCA because we largely are ONLY able to buy bitcoin as our money comes in.. which can take years and years and years before it starts to add up to any meaningful amount.
Regarding diversification, I doubt that diversification is needed at the beginning of a bitcoin investment and may well not be needed for several years into a persons bitcoin investment. and surely the most effective means of offsetting risk is to buy within a persons discretionary funds and to strive to maintain back up funds that are sufficient to protect from times in which income might be lower than expected and/or expenses are higher than expected. Of course, if a person has doubts about investing into bitcoin, then they can choose some other investments and hope that they are not overly diluting their bitcoin investment due to their choice to put time, energy and value into some other assets, and surely if a person has more discretionary funds then it might make more sense as compared with someone who at most may only be able to invest $10 to $100 per week into bitcoin.
