Litecoin

Wherever Bitcoin goes, little brother Litecoin follows.
I’m confident Litecoin will maintain market dominance due to inherit synergies (shared code) with Bitcoin, the network effect, and the compelling story of Litecoin being the silver to Bitcoin’s gold.
It’s generally agreed that Bitcoin alone cannot serve as a the global payment network. This makes an easy case for Litecoin to share the network load. Litecoin will be completely interchangeable with Bitcoin via atomic swaps on the Lightning Network.
