Maybe you are hitting on another developing pet peeve of mine?

Daily cost averaging seems to be a misleading attempt at a euphemism... and the term is not daily cost averaging, it is dollar cost averaging (this correction about the "proper" term does not have to do with the dollar.. but instead getting away from expectation that there is any kind of meaningful justification to be maniacally in regards to buying every day.. which is more of an advanced practice rather than an entry-level practice).

In bitcoin, I personally recommend accumulators (and even newbies) to figure out something on a weekly basis (or maybe bi-weekly if they are just coordinating it when their paycheck comes in, if that is how they get paid).. but sure, daily might work too - even though there seems to be too many potentialities that small amounts could fuck you up in terms of unnecessarily causing your fees to be way more than they need to be (the fee level and way of doing fees of course, vary from exchange to exchange). 

Sometimes even weekly DCA does not work for folks in lower income locations because there might be a need to get over a certain value threshold in order to cause the fees to be more effective and less burdensome...

For example, if you are able to do any amount and the fees are just a percentage - like 1% or even high fees like 3%, then it may not matter so much if you do the transactions more frequently, such as daily, but some places have a flat charge and then also a percentage after charging the flat charge.. .. so maybe there is a flat charge of $1 or $5.. or something that causes a need to attempt to lump sum rather than having a whole bunch of small transactions and ongoingly paying such a flat fee that eats into how much bitcoin you are able to get through each transaction and even overall if you add up your transactions over time you end up getting royally fucked by fees in some of those situations that have flat fee charges to supplement percentage charges. 

Seems to me that we should not want poor people to get even more poor merely because they are failing to adequately strategize ways to attempt to lessen (or minimize if possible) the various fees that they might end up paying... so fuck the idea of daily cost averaging.. that is not the proper term... it is called dollar cost averaging...
