Before Bitcoin, money was defined by State sovereignty over a territory. From now on, any community can mint its own money in form of a cryptocurrency or digital token and start trading without any central supervising authority.
Bitcoins and digital tokens are like better, smarter cash. They are programmable money. Immediately liquid, indefinitely divisible, and instantly transferable, they can be programmed to meet the needs of particular assets, rights, goods, or services or of specific communities.
