Litecoin was designed by Charlie Lee to be the so-called “silver” to Bitcoin’s “gold” in the popular analogy that compares the digital currency to the precious metal. On Wikipedia, it states that Litecoin was invented, in part, to “process a block every 2.5 minutes, rather than Bitcoin’s 10 minutes, which its developers claim allows for faster transaction confirmations.”
Litecoin has gained in popularity over its history – it was launched on github on October 7, 2011 – with a steady increase in transaction volume over time. Moreover, it is traded on many different exchanges, including Bitfinex, BTC-e, OKCoin, BitBay, Kraken, Yacuna and Huobi, BTC China and OK Coin trade the digital currency.
