Some economists have opined on BTC. 

Translation of the below paper:  good news and bad news about Bitcoin. 

Good news:  Bitcoin is here to stay, as you will always be able to use it in the black market. 

Bad news: governments will regulate it so it remains in the black market.

The Political Economy of Bitcoin
November 28, 2014
Abstract
The recent proliferation of bitcoin has been a boon for users but might pose problems for govern-
ments. Indeed, some governments have already taken steps to ban or discourage the use of bitcoin.
In a model with endogenous matching and random consumption preferences, we find multiple mon-
etary equilibria including one in which bitcoin coexists with regular currency. We then identify the
conditions under which government transactions policy might deter the use of bitcoin. We show that
such a policy becomes more difficult if some users strictly prefer bitcoin because they can avoid other
users holding currency in the matching process.
