Arithmetic on today's supply, not a forecast. It assumes nothing about whether Bitcoin Cash could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Bitcoin Cash has 20,259,525 BCH in circulation at $281.1000 each, which is $5.69B. Holding that supply still and putting OKB's $2.31B in its place gives $114.2437 per BCH.
Bitcoin Cash is already worth more than OKB. Moving to the smaller cap would take BCH down to $114.2437, which is 0.406x 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 BCH at that level, which is the part that actually decides a price.
$114.2437 per BCH. That is OKB's current market capitalisation of $2.31B divided across the 20,259,525 BCH in circulation.
0.406x. Bitcoin Cash trades at $281.1000 today and OKB's market cap is $2.31B against Bitcoin Cash's $5.69B.
No. It is one division: OKB's market capitalisation spread over the supply of BCH that exists today. It assumes nothing about whether Bitcoin Cash 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 $2.31B of market cap spread over more coins gives a lower price per coin. This uses the 20,259,525 BCH in circulation now.
