Cryptocurrency, or digital currency, is an invention of the Internet. Basically, someone out there thought, “hey, what if we can create a system where money is not bound by geography, like the internet” and lo and behold, now we have over 3000 cryptocurrencies going around.
Not all cryptocurrencies are created equal. Some feature amazing underlying blockchain technology behind its creation. Some were created ‘just because’, or as a joke. Some were part of an elaborate pyramid scheme. Some are pretty useless to keep as they are perceived as worthless – any cryptocurrency is only as valuable as the value assigned to it by a mass audience.
