Bitcoin, the digital currency, lost over $160 in value on Wednesday, just hours after hitting a record high.
The currency hit a new high of $266 before falling to $105 and then bouncing back to $130. The fall is unlikely to put off speculators. Two months ago a Bitcoin was worth $20.
With Europe racked by economic uncertainty following the banking crisis in Cyprus, there have been fears that a "bubble" is being created with speculators piling into the four-year-old digital currency. But Bitcoin has crashed before only to bounce back. It hit a low of $7 in August 2011 after hitting a high of $32 two months earlier.
