The fees of Doge, LNC are minimal even Litecoin has hardcoded fees of 1sat/bye.
No-one will switch to litecoin, it has 4mb blocksize and blocks are validated every 2.5 minture.
The fact that LTC is cheap and faster because litecoin's mempool get only 1% transaction of its total block capacity per day. and their miners have come to an agreement of fees equilibrium.
If litecoin will receive it total block space capacity's transaction , it will also face issues like bitcoin is facing and fees will be driven by market value.

Thanks for your suggestion, i will try to get their fees also.
