Goldman Sachs CEO Lloyd Blankfein  has bitcoin on  his  mind  a day after reports broke that  his  firm was considering setting up a bitcoin trading operation.
The billionaire banker tweeted on Tuesday that  he  wasn't completely sure about  his  stance on the red-hot cryptocurrency.
 Blankfein  said  he 's "still thinking about bitcoin" and that  he  was not flat out endorsing or denouncing the digital currency. Here's the full tweet:
Still thinking about #Bitcoin. No conclusion - not endorsing/rejecting. Know that folks also were skeptical when paper money displaced gold. â Lloyd Blankfein (@lloydblankfein) October 3  2017

Sunday's event was not a march  organizers say  but a rally  beginning at 10 a.m. local time inside  the Sam Boyd Stadium in Las Vegas . Officials tell Fadel that although the venue can hold 40 000  they expected roughly 17 000. The organizers say they are less concerned with crowd size than with spreading their message. Nearly two hours after doors opened  Fadel estimated that thousands â many in the movement's trademark pussyhats â had filed into  the stadium  under clear skies.

Alabama RB Bo Scarbrough  yells âFâ Trumpâ before tonightâs title game. pic.twitter.com/RhuhRyNFHh â Sporting News (@sportingnews) January 9  2018
Sounds an awful lot like  Scarbrough  shouted  âF*ck Trump!â
However   Scarbrough himself  took to Twitter late Monday night  and disputed that interpretation of what  he  said  Instead   Scarbrough  claims that  he  shouted  âF*ck Georgia!â
If yâall really listen I said Georgia smh about yâall people in this world [Link] â Bo Scarbrough (@starbo06) January 9  2018
Now  from a distance  in a crowded hallway with multiple people yelling  itâs easy to see how one could misinterpret what someone else said. However  letâs start with the claim that  Scarbrough  said âGeorgia.â
As Breitbart Deputy Political Editor Amanda House noted  âGeorgiaâ is a two-syllable word. Even accounting for different accents and dialects  a syllable is a syllable; and whatever  Scarbrough  said   it  was only one syllable.
Which causes problems for  his  explanation that  he  said a two-syllable word like âGeorgia.â Georgia also starts with a âG â and the beginning of the word  Scarbrough  shouted after  he  yelled âF*ck â seemed to clearly make a âTRâ or âCHâ type of sound.
Breitbart reported the  Scarbrough  story last night  as him saying  âF*ck Trump!â
While we have updated that story to reflect Scarbroughâs explanation  in addition to adding this piece  this is not retraction. It is still my belief that  Scarbrough  said âTrump â and not âGeorgia.â
