The price of bitcoin fell to less than $13,080 on Friday morning, according to CoinDesk.com. That makes an 18-percent drop since its previous slide, and more than 30 percent since it reached the historic $20,000 mark last week.
The cryptocurrency has experienced its second major drop in just days. Rival bitcoin cash has also fallen, plunging to $2,536 per coin , following its rapid climb of more than 50 percent to almost $4,330 per token on December 20.

Bitcoin managed to recover some of its losses within several hours, trading around $14,000 as of 9:44 GMT.
Emil Oldenburg, the co-founder of Bitcoin.com – one of the world’s largest sites devoted to the cryptocurrency – recently called the cryptocurrency the “most risky investment you can make,” after he switched to bitcoin cash, which he considers to be the future.
“The old bitcoin network is as good as unusable,” said in an interview with Swedish tech site Breakit.
