Example Input: 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.

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.

Example Input: One of the reasons  Jimmy Vesey  didnât sign with  his  hometown Bruins when the Harvard product was a college free agent in 2016 was because  he  wanted to get out of  his  comfort zone.  He  sure looks comfortable playing against them.
 Vesey  scored twice in a 29-second span in the first period in the Rangersâ 4-2 home win Wednesday night against Boston  the Blueshirtsâ fifth straight win as they continue to distance themselves from their rough start to the year.
For Buchnevichâs fellow sophomore Vesey  Wednesday represented some progress in that he remained a contributor until the final horn. In three of the previous five games   Vesey  had either had limited third-period ice time or been benched altogether for the third.

âMaybe he wasnât finishing on a lot  but  Jimmy  was working hard and  like you saw (Wednesday) early on  before he scored the goals  he made a couple real strong plays along the wall in our end that permitted us to get the puck out â Vigneault said. âSo thereâs more than just finishing.â
Example Output: Jimmy Vesey

A married father of three   Robateau  joined the force in 1994  city officials said.
âHe was one of my finest students â Rich Boggiano  a councilman and retired police detective who taught  Robateau  at the police academy  told NJ.com. âHe was a good person.â
