LTC is more cheaper and faster these days.
Is easier to mine.
It has introduced Segwit and other advanced technologies before BTC did.
Is not that reluctant to media noise as BTC is.
Is more (relatively) stabile than BTC.
I certainly agree that Litcoin (LTC) is quite faster than Bitcoin (BTC) in just a matter of minutes when these 2 cryptos are compared. Litecoin really has the edge over bitcoin which attracts traders or merchants.
But in a greater picture, these gold and silver in the cryptoworld has its own advantages and disadvantages respectively.
