The cryptocurrency market has exploded this year.

Digital currencies, such as Bitcoin, are powered by distributed ledger technology and are not controlled by a centralized authority. Cryptocurrencies have been around for almost a decade but the rapid appreciation of bitcoin and other cryptocurrencies this year has peaked the interest of Wall Street and Main Street alike.

Bitcoin, for instance, recently surpassed $4,800. It’s up over 700% since 2016 and ether, the token powering the ethereum blockchain, is up 3,300% during the same time period.

At the same time, the number of so-called altcoins, or alternative cryptocurrencies, has ballooned. Powered in part by the rise of initial coin offerings, a way for companies to raise money by creating their own cryptocurrency, the number of altcoins now stands well above 1,000 with a combined marketcap of over $170 billion, according to data from Coinmarketcap.com.

We’ve come up with a list of the nine most bizarre altcoins from Coinmarketcap’s list. Here they are:

Dogecoin was created by Jackson Palmer, a group product manager at Adobe, and Billy Markus, a software engineer at IBM, "without much real thought," according to reporting by Motherboard.

As Palmer told Motherboard's Patrick McGuire, "one night after work, I sat down with a beer, I had too much time on my hands, and I bought Dogecoin.com."

Markus stepped in to help make Dogecoin an actual currency.

The name of the coin is an homage to the popular internet meme known as Doge, which became popular in 2013 and features the face of a dog with comic sans texts in the background. Today, the coin is one of the largest alternative cryptocurrencies on the market.
