WHAT'S SO GREAT ABOUT BITCOIN?

摘要

Bitcoin is popular because it's free from the control of banks or governments. "Anyone can send money to anyone else in the world with a transaction fee of less than a dollar," says Andreas Antonopoulos, who hosts the Let's Talk Bitcoin podcast. Anyone can - but not everyone does (see main article). Digital currencies like bitcoin exist solely as records stored on computers around the world. That might seem strange, but few traditional currencies are actually linked to physical commodities like gold any more. For example, most US dollars exist only as digital records held by banks.
