First of all, Charlie Lee the creator of Litecoin appears to be a very intelligent (and modest) guy. Litecoin has a max supply of 84 million coins, 4 times more than bitcoin. Cheaper transaction fees, 4 times or more faster when transacting. If you go to a crypto atm, mostly you will find Bitcoin, Litecoin and Etherium. Which makes it easier to buy. Cnbc has listed bitcoin, litecoin and ether mainly over the last year= general public recognition. Bitcoin = store of value and litecoin = day to day, smaller transaction use cases.
