I'm with you on everything except the Bitcoin bit. I think he knew exactly that (a) it's a highly speculative asset, and (b) he has enough rabid fans and general publicity to move the market in exactly the ways that he benefits from.
Maybe you're right.
If his proclamation knocks, say, half the value off Bitcoin, and it stays there, that wasn't a very clever pump and dump, because they kinda skipped the 'dump' part.
That would be an explicit lie then, something the SEC has jurisdiction over? (I'm not actually sure)
