The value of Bitcoin has hit a new high with each individual coin now worth more than $2,100 (£1,615).
The valuation caps a strong month for the virtual currency, with its value growing by more than 65% in a month.
The steady rise in value is believed to be linked to policy changes in Japan and China that have made it easier for speculators to trade in bitcoins.
Many other virtual currencies have also enjoyed a sustained rise in value over the last few weeks.
Bitcoin first broke the $1,000 (£768) barrier in November 2013 but its value has fluctuated wildly since then. For instance, in early 2014 one bitcoin was worth only $280 (£215).
And at the end of 2016, each one was changing hands for about $900 (£690).
