The unit broke the $1,100 barrier on the Bitcoin Price Index, an average of major exchanges, to continue a dizzying rise that made it the best performing currency of 2016.
It has fluctuated wildly since it was created in 2009 and lost three quarters of its value when it plummeted from its previous BPI high of $1,165.89 in 2013.
And news of a major bitcoin theft by hackers in August sent its price plunging by more than 20 percent.
But analysts say its volatility will ease as volumes grow and point to a strengthening US dollar and tightening currency and capital controls, as well as the rise of the digital economy, as major factors behind its appreciation.
In particular, the chaotic withdrawal of high value bills in India and restrictions on buying foreign currency in China as the yuan slides against the dollar have stoked demand, analysts say.
Exacerbating the rocketing demand is a tightening supply of fresh bitcoins.
The currency was always meant to be finite, and more than three quarters of the planned 21 million bitcoins have already been 'mined'.
Encrypted digital coins are created by supercomputers and then traded online or exchanged for goods and services.
