Arithmetic on today's supply, not a forecast. It assumes nothing about whether Stellar could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Stellar has 35,383,844,588 XLM in circulation at $0.1675 each, which is $5.93B. Holding that supply still and putting OKB's $2.31B in its place gives $0.06541186 per XLM.
Stellar is already worth more than OKB. Moving to the smaller cap would take XLM down to $0.06541186, which is 0.391x 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 XLM at that level, which is the part that actually decides a price.
$0.06541186 per XLM. That is OKB's current market capitalisation of $2.31B divided across the 35,383,844,588 XLM in circulation.
0.391x. Stellar trades at $0.1675 today and OKB's market cap is $2.31B against Stellar's $5.93B.
No. It is one division: OKB's market capitalisation spread over the supply of XLM that exists today. It assumes nothing about whether Stellar 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 35,383,844,588 XLM in circulation now.
