He is actually wrong, there is something called Electrum-LTC attached to litecoin which you can confirm directly from coinmarketcap, although if you type electrum, you may not see such a thing as coin, only litecoin, but under litecoin, go on social, you will see where litecoin directly gave information about this project and the need for all users to mandatorily upgrade it.
I am not a fan of litecoin, and I dont hold any of their coin, but I had to do my little research before completely judging the OP, this market is too big for one to have every information about the market, so he is right, you can research it yourself directly under litecoin.
