Abstract
This paper introduces a noncausal autoregressive process with Cauchy errors in application to the exchange rates of the Bitcoin electronic currency against the US Dollar. The dynamics of the daily Bitcoin/USD exchange rate series displays episodes of local trends, which can be modelled and interpreted as speculative bubbles. The bubbles may result from the speculative component in the on-line trading. The Bitcoin/USD exchange rates are modelled and predicted.

Notes
- 1.
Formerly magic: the gathering online exchange.
- 2.
The transactions on this market have been suspended as of February 25, 2014. The reason is yet to be revealed, but an attack by hackers has been declared.
- 3.
It represented 12Â Â % of the trades before it collapsed.
- 4.
The difference between the sample max and min.

- 7.
Alternatively, it can be represented by a model with a stochastic trend, assumed independent of the shocks that create the speculative bubble.
- 8.
The French platform Bitcoin-Central has been closed for 5Â months in 2013 due to hackers attack. Nevertheless the customers had still the possibility to withdraw their bitcoins.
