Although I disagree with BU, I don't think it is an attack on Bitcoin itself. Remember the basic concept of Bitcoin - it's controlled by nobody!
Well the concept of BU goes against that of bitcoin - at least in practise.
With BU, you rely on some giants with their own nodes in order to transact.
Originally there was no need to depend on ANYONE but BU says no, please rely on these giants to make transactions faster... or whatever it is they really are after.
The bilderbergs don't want an economy they can't influence.
