Supposed Bitcoin founder says 'goodbye' after presenting fake evidence

``Throughout all of it, there have been a number of simple, concrete actions Wright could have taken to prove his ostensible identity: signing the genesis block, signing a message with Satoshi's PGP key, or making a transaction with one of the many bitcoin blocks linked to Satoshi.

For skeptics, that behavior is exactly what you'd expect -- and for those who believe him, it's harder than ever to explain.''
