Actually "coin" was not really a very good choice (as Andreas M. Antonopolous has pointed out many times) as "coins" are a very bad metaphor for how Bitcoin actually works (there are no coins).
The problem with new technology is that "old words" just don't fit very well - so I'm guessing the name was chosen to basically make it clear that it is a type of "money".
So if it were to be able to be renamed then the "coin" part would be what I'd drop - maybe "Bitmoney" might have been a better choice.
(to some extent I think the project eMunie has perhaps done a much better job with its name choice but I don't think that the name is really going to be the deciding factor)
bitcoin didn't spark interest to me when i first heard of it. simply because of the word "coin" to which i thought its just coins. Nothing special and probably just less than a dime.
and until an employer hired me and asked if I accept bitcoin. thats when i started to realize its great that each coin equates more than $1K.
