If you couldn’t get behind Bitcoin, the peer-to-peer digital cryptocurrency that’s as volatile as your weird uncle when he’s 3 glasses of gin deep, perhaps Coinye West is more your style.

As 2013 came to an end, many reflected on last year’s biggest tech news — and Bitcoin was a serious contender. But the main question remains: why are people interested in Bitcoin?

Bitcoin watchers everywhere let out a guttural sigh of pity when they heard the story of James Howells earlier this month. Howells inadvertently threw away $7.5 million worth of Bitcoin when he tossed out an old hard drive containing 7,500 units of the online cryptocurrency. The Welshman had purchased them back in 2009, shortly after bitcoins were introduced, for less than $6. Now he's kicking himself while digging through a British landfill.

After a record run, Bitcoin prices have tumbled back to earth after the Chinese government announced a series of bans on the currency. Here is a chart and some background.

It was only a matter of time before the 2013 meme of the year tried to turn his success into financial gain. Enter Dogecoin: a Bitcoin-like cryptocurrency that seems to have started as a joke and is beginning to actually accumulate some value. As with most things meme, there's a community on Reddit called Dogemarket where users are trading Dogecoin for actual, real-world items — though as of today, a single Dogecoin is worth only $0.00023.

Bitcoin's value plummeted today, by 25% from a high of over 1100 US dollars per BTC to a low value of under 830.

Augustus Caesar, in 13 B.C., worried that retired soldiers might rise up against the empire. So he came up with a clever solution: after twenty years in a legion and five years in the military reserves, a soldier would earn, in a lump sum, a pension that worked out to about thirteen times a legionnaire’s annual salary. Pay the veterans off, the reasoning went, and they’ll be less inclined to overthrow you.
