Yes, I'm used to thinking of Summers as a contrarian indicator. It is out of character for him to support crypto. Lest we forget - he was a leading candidate to succeed Bernanke as head of the Fed and he had a much-publicized dustup with the Winklevii when he was in a position of power and they were undergraduate supplicants.

Something is up, but what? Is it mischief or is he just starting to think about his legacy, Alfred Nobel-style? At best, it's just one more talking head to ignore.
