would kill BTC as it would avoid the whole mining tax/drama which is like flying into the head wind.
Its sorta like figuring out flight, and BTC is about a 3rd generation Flyer. NXT is a prop plane ww1 but it has a tether attached to a crane, and the fuel supply is a bit suspect.
I agree with this. Primarily the issue of anonymization - if someone had a Bitcoin clone that was completely anonymous (perhaps integrated Tor, along with making it impossible to track the flow of money from one address to another via the blockchain) it would take over. Even more so if mining of that currency was most efficiently performed on a standard computer processor, which would avoid mining centralization.
