Financial Times - FT Alphaville have been writing about Bitcoin for over two years.
http://ftalphaville.ft.com/tag/bitcoin/Isabella Kaminska, whose work I am otherwise a great fan of, does not seem to like Bitcoin much - pointing to its extreme Gini coefficient and other problems as indicative of its undesirability. She does write about it fairly regularly though.
The most interesting thing they've covered most recently is some thoughts on how Bitcoin and other crypto currencies are a possible solution to the Zero Lower Bound - and so in fact are assisting QE. It's a bit counterintuitive, but something Bitcoiners don't think about enough is that if Bitcoin and other cryptocurrencies become generally accepted as mediums of exchange, then they are actually inflationary, as they are private currencies being issued in addition to the fiat coming from the Central Bank.
I;d be happy to discuss this elsewhere -perhaps I will make a thread in Economics subforum.
