2 weeks ago, this guy said "How could a central bank trust this Bitcoin? No one has even seen its code."

He got trolled and schooled hard about it.

Maybe he learned some from it, but I doubt it's been enough to fully convince himself, and the majority of the voting members to buy in.

On the other hand, I can see that he might tempted to be forever remembered as The Esteemed And Brave central banker, who placed a little bet and made a history by retiring his nation. He's very much an ego guy, and former investment banker.
