What just happened?
Someone heard some good news before we did? At least i hope that's the case.
Probably good gox news that's not public yet....
If it's Gox news I would rather guess it's bad news.
Maybe, but there was a big meeting with the US government yesterday. Maybe something positive came out of it.
EDIT: these surprise price swings are exactly why I don't pay for ASIC's in Bitcoin.
