After BTC do the soft fork, LTC will be dead.
Can you tell me where did you get that news? Because for me LTC will not become dead even the price of ltc dump I believe they will increase again like before. I hope the price of ltc before the end of this year 0.1 bitcoin . And I hope ltc will become stronger and stronger next few months. LTC will not become dead. They will become more popular to the crypto world.
If Bitcoin gets segwit and lightning network, I don't see what use Litecoin still has? People will probably dump it for BTC. I own a little bit of LTC though, so I hope not.
Unless someone can tell us what makes LTC not obsolete, what it has that Bitcoin doesn't? (and then it's also the question: will the market agree)
