I dont know if im advancing too fast, but in the future we will do all transactions online without the need anymore of the printed money, besides that i do believe we will have internet acess for free, companies will sell just computers and digital equipments.
Real Money will always be paper and digital for use on a network. There is much debate on the subject, just much talk seriously about bitcoin such as international currency very early and premature.
I think the true real money will always be in the form of paper money, and the money will be digital only as an option, although the future of digital money later will be more widely used, but I'm sure paper money will continue to survive
Paper money can be elimanate if system between stable, paper money is many the weakness like prone to false, paper money also difficult to control by government.
