Bitcoin has jumped back to the $600 price range.

This is the highest price range that the popular digital currency has reached since the August hack of Hong Kong-based bitcoin exchange Bitfinex, in which an estimated $65 million worth of bitcoin was stolen. Since then, bitcoin’s price has been hovering at around $570

There are several factors that might have influenced bitcoin’s sharp spike in price. For one, the renewed interest in cryptocurrency could have been caused by Bitfinex’s announcement that it has found a way for its customers to convert their BFX tokens. It could also be because Russian authorities have finally admitted that a blanket ban on digital currency is “not worth implementing,” given that the technology is still evolving.

Another factor is the renewed fears of yuan devaluation among Chinese investors.
