Bitcoin has taken another step toward the financial mainstream, after a US regulator said it would let two traditional exchanges begin trading in Bitcoin-related financial contracts. CME Group and CBOE Global Markets exchanges will offer investors Bitcoin futures from later this month.
The move sent the crypto-currency's price up, continuing its volatile week.
Bitcoin hit a record above US$11,400 last Wednesday, but then lost 20% of its value in the following 24 hours.
The announcement from the Commodity Futures Trading Commission (CFTC) that it will allow the futures to be traded was seen as a watershed moment for the currency.
It means that investors will be able to buy and sell future contracts in Bitcoins - an agreement to buy the crypto-currency, for example, in three months time at a certain price.
CME Group said trading would be available on its CME Globex electronic trading platform from 18 December. To guard against volatility, CME and CBOE will put in place stricter than usual risk-management safeguards.
CME and CBOE have also agreed to enter into data-sharing agreements, particularly on the settlement process, so the CFTC can conduct its own surveillance on the new financial contracts.
Bitcoin's rapid rise from less than US$800 in December last year to more than US$11,000 this week on Coindesk has stoked fears that it is a pricing bubble that could leave recent investors worse-off.
JPMorgan Chase chief executive Jamie Dimon called Bitcoin a fraud at a conference in early September, while Goldman Sachs boss Lloyd Blankfein has questioned whether the crypto-currency is a currency at all, given its volatile pricing. It doesn't feel like a store of value, he has said.
