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 Hedera's $3.3B in its place gives $1.9433 per DOT.
The two are close in size, so the answer is a 1.91x move. Polkadot and Hedera 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.
$1.9433 per DOT. That is Hedera's current market capitalisation of $3.3B divided across the 1,700,506,167 DOT in circulation.
1.91x. Polkadot trades at $1.0190 today and Hedera's market cap is $3.3B against Polkadot's $1.73B.
No. It is one division: Hedera'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 $3.3B of market cap spread over more coins gives a lower price per coin. This uses the 1,700,506,167 DOT in circulation now.
