Market capitalizations of certain coins have little meaning in illiquid markets. e.g. a coin is formed with 1 billion coins pre-mined. One coin is sold for 10 USD. Now it has a capitalization of $10 billion. We are seeing the illiquidity in bitcoin cash - if there is no market demand then the valuations need to be viewed in this context.
Also comparing Litecoin to the market cap of a company while interesting , it is more of a currency like Bitcoin that should be compared to overall money supplies, e.g. M1 etc.
