LONDON Jan 2 Digital currency bitcoin kicked
off the new year by jumping above $1,000 for the first time in
three years late on Sunday, having outperformed all
central-bank-issued currencies with a 125 percent climb in 2016.
Bitcoin - a web-based "cryptocurrency" that has no central
authority, relying instead on thousands of computers across the
world that validate transactions and add new bitcoins to the
system - jumped 2.5 percent to $1,022 on the Europe-based
Bitstamp exchange, its highest since December 2013.
