Bitcoin and Litecoin are essentially virtual digital currencies, but the creation of Litecoin is an improvement on Bitcoin. It is significantly different from Bitcoin. The Litecoin network produces blocks faster than Bitcoin and can provide faster Transaction speed. The amount of currency issued by Litecoin is more than four times that of Bitcoin.
However, the price and transaction volume of Bitcoin is much greater than that of Litecoin. Litecoin is just a copy of Bitcoin. Bitcoin has a greater market value, a longer history, and a stronger consensus. No one would choose to abandon Bitcoin and choose Litecoin.
