Must see Finextra Youtube video interview with Richard G. Brown, a CompSci expert who works for IBM, who is bullish on bitcoin but around 3:30 states it is not anonymous, and eventually Big Brother is going to use it to tax people under an 'asset register' scheme.
But Brown's bullish on bitcoin, even though bitcoin is not anonymous. At 9:00 he discusses how machines can trade bitcoin amongst themselves! @10:20 "On the blockchain, nobody knows that you're a fridge"!
@10:45 bitcoin will not be the only cryptocurrency. Litecoin is a 'psychological' play, and others.
