To say that the world of finance has only become murkier the more it has intertwined with technology is an understatement. The rise of digital money and cryptocurrencies like bitcoin has only made it all that much stranger, too. Where dollars — or pounds, rand, yen, euros, and so on —are issued by nations, cryptocurrencies exist online, out in the ether. They're not quite the same as cash — you can't hold them in your hand, for example, and few businesses accept bitcoin for payment, let alone dogecoin or ethereum or any of the various other cryptocurrencies.
It's all a bit difficult to grasp unless you have a lot of free time on your hands to really get in depth.
And, as it turns out, even those who think they know what they're doing with digital money can get pretty confused.
