Arithmetic on today's supply, not a forecast. It assumes nothing about whether Dogecoin could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Dogecoin has 171,357,000,922 DOGE in circulation at $0.08482 each, which is $14.53B. Holding that supply still and putting XRP's $85.78B in its place gives $0.50056385 per DOGE.
A 5.90x 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 DOGE at that level, which is the part that actually decides a price.
$0.50056385 per DOGE. That is XRP's current market capitalisation of $85.78B divided across the 171,357,000,922 DOGE in circulation.
5.90x. Dogecoin trades at $0.08482 today and XRP's market cap is $85.78B against Dogecoin's $14.53B.
No. It is one division: XRP's market capitalisation spread over the supply of DOGE that exists today. It assumes nothing about whether Dogecoin 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 $85.78B of market cap spread over more coins gives a lower price per coin. This uses the 171,357,000,922 DOGE in circulation now.
