A crash course in changing the world.
I believe that DIY Currency and Paypal have it correct with the methods of utilizing currency in the future. Tangible funds are seemingly becoming more and more burdensome and obsolete. People want access to money and not only as much as their wallet can hold. With electronic methods of delivering, sharing, or even coming up with currency, controlling ones funds will be more convenient but their are quite a few cons to have access to all ones money through a direct source. Nevertheless this is more efficient and will be what the people want.
