IMO only revolution or total banks crash could force average "normal" people to commonly use bitcoin. Without that it will be interesting thing for some geeks and blackmarketers.
Well yes but never say never.... problem is organization, banksters have major organization though control of the exhcnage system which results in everyone working for them.
Re bitcoin I will be helping by letting people exchange service through fixxi.net but more is needed, especially getting offline people to use accept Bitcoin as pay for their labour. For that to happen other people who create products and services must have started accepting bitcoin.
