I do think one of the reasons why Litecoin only has price of $41,68 today (1,6% of BTC) is due to a logical fallacy.
As we all know from the start Litecoin has been dubbed the silver to Bitcoin’s gold, a supposedly worthy title because of the ‘similarities’ between the two.
However, gold and silver are not similar at all. They have distinct properties and different uses: Silver is also an industrial metal.
On average, silver exists at a 17:1 ratio versus gold in the Earth's crust, thus gold is much more scarce.
Technologically, Litecoin has block times of 2.5 minutes - four times faster than Bitcoin - that actually makes a huge difference in terms of practical utility.
LTC is also more energy-efficient, where BTC is estimated to consume that same amount of energy as Denmark by 2020.
Litecoin does not have any scaling issues at present.
Usually, there is a correlation between scarcity and price.
With potentially 84 million LTCs rather than 21 million BTCs, Bitcoin is 4 time more scarce than Litecoin.
One could argue that the price of Bitcoin should be 4 times the price of Litecoin.
Gold and silver are the World of Atoms, whereas BTC and LTC are the World of Bits. Certainly, BTC vs. LTC is not scarce in a gold vs. silver sense.
