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 77,121,117 LTC in circulation at $54.1600 each, which is $4.18B. Holding that supply still and putting Polkadot's $1.71B in its place gives $22.2065 per LTC.
Litecoin is already worth more than Polkadot. Moving to the smaller cap would take LTC down to $22.2065, which is 0.410x of what it trades at now.
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.
$22.2065 per LTC. That is Polkadot's current market capitalisation of $1.71B divided across the 77,121,117 LTC in circulation.
0.410x. Litecoin trades at $54.1600 today and Polkadot's market cap is $1.71B against Litecoin's $4.18B.
No. It is one division: Polkadot'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 $1.71B of market cap spread over more coins gives a lower price per coin. This uses the 77,121,117 LTC in circulation now.
