Arithmetic on today's supply, not a forecast. It assumes nothing about whether Shiba Inu could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Shiba Inu has 588,828,612,922,199 SHIB in circulation at $0.00000526 each, which is $3.1B. Holding that supply still and putting Polkadot's $1.71B in its place gives $0.000002908465 per SHIB.
Shiba Inu is already worth more than Polkadot. Moving to the smaller cap would take SHIB down to $0.000002908465, which is 0.553x 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 SHIB at that level, which is the part that actually decides a price.
$0.000002908465 per SHIB. That is Polkadot's current market capitalisation of $1.71B divided across the 588,828,612,922,199 SHIB in circulation.
0.553x. Shiba Inu trades at $0.00000526 today and Polkadot's market cap is $1.71B against Shiba Inu's $3.1B.
No. It is one division: Polkadot's market capitalisation spread over the supply of SHIB that exists today. It assumes nothing about whether Shiba Inu 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 588,828,612,922,199 SHIB in circulation now.
