Atomic swaps, are trades between different chains. Recently the creator of Litecoin Charlie Lee recently did an atomic swap with someone else. It was a trade directly between Bitcoin And Litecoin with no exchange needed, He basically swapped 11 Litecoins for 0.1 of a Bitcoin without an exchange, This means there are almost no fees and you don't need an intermediary when trading different Coins. Also, I see Litecoin returning to its high of 90, maybe breaking the 100$ mark by the end of October.
