question:
Bitcoin's price has fully recovered from  its  recent slump after  JPMorgan CEO Jamie Dimon  called it a fraud and Chinese regulators cracked down on exchanges.
The cryptocurrency had a drawdown of up to 14% in the 10 days after September 12  when  Dimon  compared it to the tulip bubble of the 1600s and vowed to fire traders who used it.
By Thursday  bitcoin had all of the losses. It was up nearly 2% from the lows on the day  Dimon  spoke  at $4157.31 per coin at 10:28 a.m. ET.
The move illustrates bitcoin's wild volatility; it's gained 331% this year  unheard of for any major currency and most financial assets. It also shows why many Wall Street professionals like  Dimon  don't see it as a legitimate store of value but as a speculative instrument.
answer:
Jamie Dimon


question:
Prince Harry  refused to take part in the Royal Familyâs traditional Boxing Day shoot on Tuesday so as not to upset  his  âpart-veganâ activist fiancÃ©e  according to reports.
Gamekeepers at the Sandringham estate  where  Harry  first joined  his  family at the annual shoot more than 20 years ago  were âstunnedâ by the princeâs decision  according to The Sun.
â Harry  loves it and has always been out there on  Boxing Day . But if it means breaking with long-standing royal traditions to avoid upsetting her  so be it. Itâs fair to say that there are some pretty stunned faces around here.â
A friend of  Harryâs  said: âIf Meghanâs not comfortable with  him  doing the shoot   he  wouldnât want to upset her.â
On Wednesday  Prince Harry and the BBC were criticised for producing a politicised âinterviewâ with Barack Obama in which the former president launched a thinly-veiled attack on his successor Donald J. Trump.
answer:
Harry


question:
â Sen. Kamala D. Harris (D-Calif.)  on Twitter  Nov. 17
One of the most widely shared claims came from  Sen. Kamala D. Harris  who tweeted   âRetweet if you would *not* benefit from a private jet tax break â on Nov. 17  linking to a Business Insider article with the headline  âThe Republican tax bill has a provision that would end a headache for private jet owners.â  Harris âs tweet prompted nearly 69 000 retweets and more than 35 000 likes.
 Harris âs claim that the Senate bill contains a provision for a tax break on private jets comes from the Business Insider article  she  linked to in  her  tweet. The article explains how the Senate version of the GOP tax bill makes tax changes to specific industries  noting that the âthe Tax Cuts and Jobs Act would correct a long-running dispute between owners and operators of private jets and the IRS.â
 Harris  defends  her  tweet  arguing that they are simply describing the provision as it was reported in the media as a tax break. But that was not the case with the article she retweeted â which also noted that the tax provision was valued at less than $50 000 a year. Moreover  several outlets offered a detailed take on the provision  making clear it the clause aimed to settle a decades-long dispute between the IRS and private jet management companies.
Still  these tweets are not alike.  Harris  earns Three Pinocchios for referring to a âprivate jet tax breakâ and suggesting wealthy owners would gain.
answer:

Kamala D. Harris
