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.
Simply because DCA has become a generic term. People do DCA in their local currency, which is not necessarily dollars. And then if you want to find a calculator, for example, to find out how much you would have earned by investing such and such a sum, then you go and search for “DCA bitcoin”.
