Litecoin is a Bitcoin altcoin that was created in 2011 via a fork in the Bitcoin source code. This makes it one of the oldest cryptocurrencies in existence. Litecoin is a peer-to-peer digital currency that offers many of the same features as Bitcoin. Like Bitcoin, Litecoin is an open-source cryptocurrency that enables peer-to-peer payments without a central authority. Litecoin is also one of the biggest cryptocurrencies in terms of value, having hit a market capitalisation of $15 billion in November 2014.
