Question: Bitcoin hit a record high of $16 623 per coin on Thursday  December 7. Two years ago  the idea of buying the virtual currency even at that price was laughable. After a rapid rise in value in 2013  the cryptocurrency's value more than halved by mid-2015. At its lowest point  one bitcoin was equal to about $230. Given the currency's covert nature  the average person still may not understand how buying and selling actually works. Using the app Coinbase  which lets anyone trade bitcoins for a small fee  we decided to find out. A brief warning: If you're going to do this  tell your bank you're about to buy bitcoin. More on that later. And to read more about blockchain  the technology powering bitcoin  click here. View As: One Page Slides
This is what the Coinbase app looks like on an iPhone.
However  Coinbase's interface makes it simple to enter the basic personal information it needs to create your account.
The final step before entering my financial information was two-step verification for security  which  Coinbase  quickly sent to my phone.
To sell the bitcoin   Coinbase  only allows users to pair  their  bank account with the app; a credit or debit card won't suffice.
Since  Coinbase  wasn't linked to my bank account  the transaction needs a few days to process before the money is transferred.

Answer: Coinbase


Question: What happens when the one and only Bill Murray recites American literature and flexes his pipes on songs from the great American songbook  backed by three accomplished classical musicians at a packed Orchestra Hall?
âNew Worlds:  Bill Murray   Jan Vogler and Friendsâ was the name of the show the famed Wilmette-raised actor and comedian  along with cellist Jan Vogler  violinist Mira Wang and pianist Vanessa Perez  brought to Symphony Center on Tuesday night as part of a national tour in support of their new Decca Gold album of the same name.
 Murray  sang a little  danced a little  cracked a couple of jokes. The inveterate Cubs fan traded his tuxedo jacket for a Cubs windbreaker at the end  prompting a roar from audience members  one of whom had draped a Wrigley victory flag over the side of the platform that was put up on stage to accommodate extra seats.
The tone shifted from light to serious and back again.  Murray  sometimes recited over musical accompaniment; sometimes  his  recitations stood on their own. One selection merged into the next in a seamless  two-hour flow of spoken word  song and instrumental music. Like all highly skilled actors   Murray  is a virtuoso of tone and timing.  His  typically laid-back manner fools no one  for thereâs always a finely honed theatrical sensibility and command of craft peeking through.
Who could resist James Fenimore Cooperâs evocation of a pristine early 19th-century American woodland (from âThe Deerslayerâ)  as recited with all due wonderment by  Murray  over a movement from a Schubert piano trio?
Or  Murray âs thoughtful rendition  half-sung  half-spoken  of âJeanie with the Light-Brown Hair â a nostalgic slice of early America I have never heard so poignantly done as here?  Murray  may not have classically trained vocal technique  but  his  baritone is pleasant and musical and absolutely true to the words and the deep emotions they convey  and that was all that mattered.
There was so much else to savor all evening long. You havenât heard âIt Ainât Necessarily Soâ until youâve heard  Murray âs sassy  jazzy transformation of that beloved Gershwin classic. Nor are you likely to forget the gutsy intensity of feeling he brought to Van Morrisonâs soul standard âWhen Will I Ever Learn to Live in God.â
After that number   Murray  flung long-stemmed roses to the fans  who were up on their feet  loudly cheering the hometown favorite. âThanks for coming â itâs nice to be home â he told them  as he  Vogler  Wang and Perez waved their goodbyes.
If this is what it takes to sell light classical music and renew interest in neglected classics of American literature to a mass concert public  maybe  Murray  and friends are on to something. Long may their team flourish.

Question: Winston Peters  leader of the New Zealand First Party  speaks during a media conference in Wellington  New Zealand  September 27  2017. REUTERS/Charlotte Greenfield
 New Zealand First leader Winston Peters  told local media that knowing the facts “puts us in a better position to make judgements”.
 Peters  has said  he  would only make a decision on which party to back after the final tally and after the results become official on Oct. 12.
But some say  Peters  could be swayed to go to National given it would be a straightforward coalition between two parties.
 Peters  a veteran New Zealand politician who has now held the balance of power three times   has in past elections formed coalition governments with both the National Party and Labour.

Answer:
Winston Peters
