You make all of these claims, and yet when I say I gave someone "3 dollars" no one thinks "a full dollar must be transacted because the countable noun version conjures an integral entity", and it isn't because of the existence of "cents": one often says "three and a half dollars". Meanwhile, the word "dollar" was itself originally _a unit of weight_ that represented a quantity of silver (371 4/16th grains), and so was in point of fact "much more like giving another user a specific mass of metal in the form of on or more ingots"... at which point you hopefully realize that, in most English, units of weight use countable nouns: we don't talk about "3 gram", we say "3 grams". Essentially, this becomes some kind of semantic question about whether "Bitcoin" is the measure (like dollars) or the metal (like silver), but as that distinction has been blurred now for a long long time with common currencies (such as the US dollar, which is measured in dollars), it seems like a totally pointless argument that, in fact, causes no practical confusion to anyone.
