Arithmetic on today's supply, not a forecast. It assumes nothing about whether Polkadot could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Polkadot has 1,700,506,167 DOT in circulation at $1.0190 each, which is $1.73B. Holding that supply still and putting Cardano's $7.61B in its place gives $4.4756 per DOT.
A 4.39x move is modest, and a coin this far down the table reaching the one above it is the ordinary shape of a cycle, not an outlier.
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 DOT at that level, which is the part that actually decides a price.
$4.4756 per DOT. That is Cardano's current market capitalisation of $7.61B divided across the 1,700,506,167 DOT in circulation.
4.39x. Polkadot trades at $1.0190 today and Cardano's market cap is $7.61B against Polkadot's $1.73B.
No. It is one division: Cardano's market capitalisation spread over the supply of DOT that exists today. It assumes nothing about whether Polkadot 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 $7.61B of market cap spread over more coins gives a lower price per coin. This uses the 1,700,506,167 DOT in circulation now.
