I don't know how stupid this may sound, but why do we say dollar cost averaging, DCA, instead of Satoshi cost averaging, SCA or Bitcoin cost averaging, BCA?
Why DCA, instead of BCA?
This is owing to the fact that we could associate any legal currency with cost averaging as a strategy of investment for either short or long term durations.
I don't think you need to be serious with these terms as they are all about averaging cost of your investment. You can replace Dollar (aka. US dollar) with your national fiat currency and there are many fiat currencies to replace there, or with Bitcoin or with satoshi. It's not big matter at all.
