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.
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 on Friday. It later recovered to trade around $6,880, but that was still down almost 4 percent on the day.
As bitcoin tumbled, Bitcoin Cash, which was generated from another software split on Aug.1, surged, trading up as much as 35 percent on the day to around $850, according to industry website Coinmarketcap.
Investors that see bitcoin more as a currency than a store of value might be choosing to buy into Bitcoin Cash now that Segwit2x has been scrapped.
