Bitcoin's inexorable rise towards $10,000 continued on Tuesday, looking at one point it could make the landmark level by the end of the day.
By some measures Bitcoin has already passed $10,000, including on the CEX cryptocurrency exchange, but the listing on Reuters showed the cryptocurrency was up 1.63% at $9,887.
Given recent volatility in the currency, however, it could conceivably reach five figures by the end of the day - or even fall back below $9,000.
Such has been the meteoric rise is has come under much analyst scrutiny.
Nicholas Gregory, chief executive of CommerceBlock, the cryptocurrency business enabler, said: "The current momentum is less technical than systemic."
