*In before the shills and trolls
Main difference between litecoin and bitcoin is Litecoin will have 84 million coins and bitcoin will max out at 21 million coins.Litecoin uses scrypt where as bitcoin uses sha-256.It's important to also know that LItecoin devs also work on improving bitcoin.There's a reason Litecoin is the number 2 coin.
I suggest holding both bitcoin and litecoin.
