Ahead of the launch of their own Bitcoin exchange, tech entrepreneurs Cameron and Tyler Winklevoss say the nascent cryptocurrency isn't primed for mass adoption just yet, but it will one day rule the financial world.
At 20, Wences Casares launched Argentina's first Internet service provider. Now 40, and with several successful startups under his belt, the serial entrepreneur is on a mission to bring financial security to underserved communities through Bitcoin.
Bitcoin is a decentralized digital currency that can be exchanged directly from peer to peer. Unlike modern fiat money, Bitcoin, which has often been called 'cash for the Internet,' is not printed like dollars or other fiat currency and it is not controlled, backed or distributed by any bank or central government authority. An estimated 11 million bitcoins are in circulation today, though only 21 million bitcoins can ever be created.
