Nick stated on Oct 27th "We have purposely not reached out to Tesla as we aren't ready yet. We have the ability to reach sr. management, but want to be ready with a good story about scaling and process." And that was just a couple weeks ago, so I have my doubts about the Tesla rumor.

Aside from that, with the current instability in bitcoin (after the dev's decided to drop the upgrade to Segwit2x), then I expect to see a rise in many of the altcoins, especially solarcoin. So in my opinion, now is probably a good time to buy solarcoin, but has nothing to do with the PBC nor Tesla rumors (as both of those seem to be hoaxes).

I do agree that this coin will likely be a top-10 coin someday.
