Arithmetic on today's supply, not a forecast. It assumes nothing about whether Litecoin could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Litecoin has 77,321,839 LTC in circulation at $54.2200 each, which is $4.19B. Holding that supply still and putting Bitcoin Cash's $4.51B in its place gives $58.3697 per LTC.
The two are close in size, so the answer is a 1.08x move. Litecoin and Bitcoin Cash are within a factor of two of each other by market capitalisation.
Supply is held still, and in practice it moves: coins are minted, burned and unlocked, and every one of those changes the price a given market capitalisation implies. The figure also says nothing about whether the money exists to buy LTC at that level, which is the part that actually decides a price.
$58.3697 per LTC. That is Bitcoin Cash's current market capitalisation of $4.51B divided across the 77,321,839 LTC in circulation.
1.08x. Litecoin trades at $54.2200 today and Bitcoin Cash's market cap is $4.51B against Litecoin's $4.19B.
No. It is one division: Bitcoin Cash's market capitalisation spread over the supply of LTC that exists today. It assumes nothing about whether Litecoin could attract that much money, and it holds the supply still when in practice supply changes.
It sets it. Market cap is price times circulating supply, so the same $4.51B of market cap spread over more coins gives a lower price per coin. This uses the 77,321,839 LTC in circulation now.
