Im confused why people would say using Myetherwallet to stock LTC,LOL. You can check out the official website of Litecoin (
https://litecoin.org/), where a variety of Litecoin downloads are available.
i guess that theyre just outrightly giving recommendation without even knowing what the coin is lol. for free alternative thats convenient enough it's jaxx i guess but i'd recommend hardware wallet instead many of them are supporting many varieties of altcoin including litecoin and not limited to ethereum blockchain
