Litecoin

Litecoin is regarded as Bitcoin's leading rival at present, and it is designed for processing smaller transactions faster. It was founded in October 2011 as "a coin that is silver to Bitcoin’s gold,” according to founder Charles Lee. Unlike the heavy computer horsepower required for Bitcoin mining, Litecoins can be mined by a normal desktop computer. Litecoin’s maximum limit is 84 million – four times Bitcoin’s 21-million limit – and it has a transaction processing time of about 2.5 minutes, about one-fourth that of Bitcoin.
