@alyssa85, it's a mix of hype (btc can't activate it, ltc can) plus the fact that segwit enables LN, plus new asic miners which are extremely efficient so the miners will benefit alot from these miners and higher prices. Plus the fact that most ltc is in chinese hands therefore they control most of the supply which means they can pump it alot, and the fact that they mine it is a double win. I think this is why @iamnotback thinks ltc may reach ATH, assuming segwit's activating.
Other projects with segwit don't matter because they are too small, no network effect, no brand recognition, etc. Did i miss anything ?
Speculation is future looking. If Litecoin gets LN and Bitcoin doesn't, then LN is the top contender for (private fractional reserve banking) scaling that will be acceptable to those who support only Satoshi's PoW.
Ethereum is next best contender for LN clone Raiden, but Ethereum is for a different crowd of speculators who believe in more uses for blockchain than just payments. Not for the conservative Bitcoin maximalists. I'll be trading some back into ETH (taking profits to recover original investment and let the rest ride) after the big move up in LTC, if I am correct about that. (Otherwise I'll be licking my wounds)
After that is bunch of dogshit coins that nobody (who knows technology of blockchains well) gives a hoot about except to pump and dump, except maybe Monero and Zcash but I'm waiting for a re-entry point in Monero below $15.
