I only know 3-4 and of them only one or two would I call serious about the tech and ideas behind Bitcoin.
It is such amazing monetary technology yet so many people seem brainwashed into accepting the state fiat monetary monopoly that is imposed upon us.
Early on I would tell friends and family about this new technology but most just did not get it, some being quite hostile to the whole idea of being free of the banks and government.
Why do so many people accept being sheep/slaves?
