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 1,692,279,772 DOT in circulation at $1.0120 each, which is $1.71B. Holding that supply still and putting Sui's $2.96B in its place gives $1.7501 per DOT.
The two are close in size, so the answer is a 1.73x move. Polkadot and Sui 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 DOT at that level, which is the part that actually decides a price.
$1.7501 per DOT. That is Sui's current market capitalisation of $2.96B divided across the 1,692,279,772 DOT in circulation.
1.73x. Polkadot trades at $1.0120 today and Sui's market cap is $2.96B against Polkadot's $1.71B.
No. It is one division: Sui'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 $2.96B of market cap spread over more coins gives a lower price per coin. This uses the 1,692,279,772 DOT in circulation now.
