Bitcoin dropped below $7,000 on Friday to trade more than $1,000 down from an all-time high hit on Wednesday, as some traders dumped it for a clone called Bitcoin Cash, sending its value up around a third.
Bitcoin has been on a tear in recent months, with a vertiginous sevenfold increase in value since the start of the year that has led to many warnings the bitcoin market - now worth well over $100 billion - has become a bubble that is about to burst, APA reports quoting Reuters.
It reached a record high of $7,888 around 1800 GMT on Wednesday after a software upgrade planned for next week that could have split the cryptocurrency in a so-called “fork” was suspended.
But it has quickly retreated from that peak, falling to as low as $6,718 around 1330 GMT on Friday. It later recovered a touch to trade around $6,880 by 1645 GMT, but that was still down almost 4 percent on the day.
