None of the major nations are going to support the Bitcoin. So I expect the global bitcoin hub to come somewhere in the smaller nations. It can come up in the semi-independent nations such as Jersey or the Cayman Islands, or it can be in the nominally independent nations such as Dominica and Grenada. Singapore is another attractive destination, but to be honest, it is a long shot.
Why not? London seems to be positive about bitcoin with even some politicians like George Osbourne encouraging it.
Bitcoin it about decentralizing, a central hub is the exact opposite.
Hub is just a silly buzzword journalists like to use. Means nothing really, but its natural that bitcoin adoption will start off in smaller places and businesses grow around it. Hopefully this happens all over the world rapidly not just one or two places.
