For someone who says he shuns the limelight, Craig Wright has chosen an oddly high profile way of laying claim to the title of digital genius behind the Bitcoin phenomenon.

If he wanted to keep his identity secret, did he really need to hire a public relations consultancy to broadcast it to the world, or to provide an elaborate series of “proofs” that he is indeed Satoshi Nakamoto, the pseudonym by which the Bitcoin mastermind has long been known?

And if he really doesn’t care whether people believe him or not, as he claims, why didn’t he simply ignore the speculation, or even deny it and let things rest at that? Mr Wright protests too much. His faux modesty fools no-one, and only lends support to gathering scepticism around his claims.

Yet if Mr Wright is indeed Mr Nakamoto, can anyone blame him for wanting to take a bow?
