Bitcoin rises sharply amid global tensions over its uncertain future

Bitcoin rose sharply on Monday, climbing above $3,400 in a move traders ascribed to heavy buying on Japan and Hong Kong-based exchanges.

The original cryptocurrency jumped as much as 11 per cent on the Bitstamp platform and was headed for its biggest daily rise since Nov. 28.

Bitcoin has fallen around 80 per cent from its record high last December. In the last three months, it has fallen nearly 50 per cent.
