I'm thinking this Andrew Laurus person must be the source.
Evidence from twitter:
Bitcoin examiner, which "broke" the story
follows himHarriet Agnew, the WSJ repoter
follows himAdditionally, Agnew follows Bitcoin Examiner, and Bitcoin Examiner follows Agnew. Interestingly Kim Dotcom follows him as well
Now, it's entirely possible all these people started following eachother after the story broke.
Now, some people are saying the Laurus twitter account is fake, which it could be. But I'm guessing it's not.
So, my theory is that
if the story is fake then it's probably been faked by Andrew Laurus. Why would he fake it? One might simply be that he's talking up something to journalists in order to impress them and boost his "cred" in the bitcoin world as someone who can get big deals done.
Another might be that he's heavily invested in bitcoin and trying to make the price go up by making it seem like big players are involved.
Or similarly he could be invested in another one of these chip ventures (such as HashFast, which also follows him
follows him on twitter) and wants to drum up other interest from big investors in other chip projects.
Another could very well be that he's trying to scam other rich people into getting "in" on the deal.
A final possibility is that there is a deal and Joe Lewis just didn't want to publicly acknowledge it to the reporter on twitter. I do find the $200 million price to be ridiculously over the top, though. Bitcoin would have to be worth at least $2k, IMO, for that to even begin to make any kind of rational sense.
