Litecoin is a cryptocurrency that was created as a lighter version of Bitcoin, with a faster block generation time and lower transaction fees. It was designed to be a more practical and efficient alternative to Bitcoin for everyday transactions. Litecoin is used in the same way as other cryptocurrencies, as a digital asset for purchasing goods and services or for investment purposes. Its main differentiating factor from other cryptocurrencies is its faster block generation time and lower fees, which make it more suited for smaller transactions.
