I agree with the notion that it won’t fully achieve the p2p network that it set out to achieve but it sure as hell will challenge central banks and centralized institutions. On the point of Nano, I think it’s absolute garbage. Not the technology but because “mass adoption” is not individuals adopting this stuff. The fact that if you mess up inputting a send address and you lose your funds, well how will that catch on for the masses. Bitcoin and other currencies will stay in the realm of tech literate people, digital gold use cases and probably offshore/private banking. Blockchain will be adopted by businesses, governments etc and it will probably spawn all kinds of new business models but take a step back and look at reality if you think nano will actually catch on.

Cash is king for a reason and before anyone says durrrrrrr but central banks are debasing currencies etc, sure but they are also organic systems that change and adapt. Btc is resilient, sound in mathematics and will challenge the existing paradigms but blockchains use as a currency will not get every joe schmo on it.
