I think
The recent Sveriges Riksbank Prize in Economic Sciences or Nobel prize (as commonly known) was actually awarded to an economist (Fama) who claimed that markets are efficient and any prediction of it's movement is fruitless. Isn't the Bitcoin price random too?
Furthermore, we can even fit Robert Schiller's theory into it. There is clearly a long-term trend and crazy volatility. Also, Bitcoin tries modelling the ideal world scenario of no transaction fee as used when designing theory like CAPM.
With such similarities, why isn't research being done in the Bitcoins? There's so little to read. We pretty much end up with Satoshi's paper which is more cryptography and less economics.
I think that bitcoin and cryptocurrency have became on many economists' list especially in the recent years since everything has became digitalized, its that the bitcoin and the crypto don't represent a large portion of the the over all investments therefor they don't impact the economy in a major way just yet, but they are still providing a good alternative to the current financial system which is proven to be less reliable and surely will see the crypto rise in the future.
