There was a time (not too long ago) that CME was getting ready to be purchased by SBF. Did you forget that already?
Duffy was 100% against this and naturally opposed it. He even went so far as to call SBF a joke, and took a lot of push-back at the time for stating that.
And to make a further point, he mentioned on CNBC had the deal with FTX gone through, it would have caused a 'biblical disaster'. There were some other interesting tid-bits mentioned, that even went outside of crypto, but we'll save that for a later date.
