It's both. Satoshi successfully released and launched the Bitcoin protocol, and it is a peer-to-peer electronic cash, it's just not a widely used one, but it doesn't make it any less decentralized or electronic. Of course there will be always work to do, just like with any other complex software, so in some sense Bitcoin will never be finished, but that's a good thing, because it means that Bitcoin is progressing and adapting.

Some people would say that Bitcoin can only succeed if it's adopted by a lot of people, but I don't agree with that, as long as there's at least some users, then Bitcoin is not useless.
