The Brutal Truth About Bitcoin

Even after the recent fall in their prices, the total market value of all cryptocurrencies now exceeds $1.5 trillion, a staggering amount for virtual objects that are nothing more than computer code.

Bitcoin was created as a way to conduct transactions without the intervention of a trusted third party, such as a central bank or financial institution.
