Arithmetic on today's supply, not a forecast. It assumes nothing about whether Canton could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Canton has 39,597,663,086 CC in circulation at $0.09806 each, which is $3.88B. Holding that supply still and putting XRP's $85.99B in its place gives $2.1717 per CC.
Canton would have to take on $82.11B of new money to get there. A 22.1x move is large: it happens, and it usually needs the whole market to grow instead of one coin to take share from another.
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 CC at that level, which is the part that actually decides a price.
$2.1717 per CC. That is XRP's current market capitalisation of $85.99B divided across the 39,597,663,086 CC in circulation.
22.1x. Canton trades at $0.09806 today and XRP's market cap is $85.99B against Canton's $3.88B.
No. It is one division: XRP's market capitalisation spread over the supply of CC that exists today. It assumes nothing about whether Canton 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 $85.99B of market cap spread over more coins gives a lower price per coin. This uses the 39,597,663,086 CC in circulation now.
