I watched this new video interview with Kim and I noted some crucial info he said about this project:

"We will not know our users, we will not know the contents of the files, will won't have upload IP address for any files uploaded to the servers so it will be the most private cloud system ever invented.
And on top of that we will have solution called Bitcache where every file transfer is linked to micro bitcoin transaction. We utilizing the blockchain, we utilizing this new digital currency and linking it to every file transfer."

This is what Kim said about Bitcoin in this presentation. So what do you think now?
