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 Bitcoin's $1.55T in its place gives $916.1572 per DOT.
This is the huge end of the comparison. Polkadot would need $1.55T more than it carries today, and at that size it would be one of the largest assets in the world, crypto or otherwise.
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.
$916.1572 per DOT. That is Bitcoin's current market capitalisation of $1.55T divided across the 1,692,279,772 DOT in circulation.
905x. Polkadot trades at $1.0120 today and Bitcoin's market cap is $1.55T against Polkadot's $1.71B.
No. It is one division: Bitcoin'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 $1.55T of market cap spread over more coins gives a lower price per coin. This uses the 1,692,279,772 DOT in circulation now.
