The idea, in short, would be that Bitcoin and Litecoin are the only two coins with Segwit implemented.
these are not actually the only two coins, there are a couple more altcoins (i think at least 5 others) but they are small ones with no significance.
This, solves the transaction malleability problem and allows them to implement Lightning Network,
from what i have understood SegWit does not "allow" LN, it makes it much easier and better.
and you know it is all about being the same code. LTC and BTC are almost like copies which makes importing code easier and they can work together much better.
wich will create an over blockchain layer that can abstract each coin specs, making possible transactions between BTC and LTC without needing to convert the coins.
in other words this awesome thing called "atomic swap"
Bottomline: this could bring big value to Litecoin, if implemented.
100% agree.
LTC is now on the long game. we can clearly see that after the rise the price never fell down hard. it just got corrected. and it is still above $40
