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 35,134,151,599 XLM in circulation at $0.1779 each, which is $6.25B. Holding that supply still and putting NEAR Protocol's $3B in its place gives $0.08552696 per XLM.
Stellar is already worth more than NEAR Protocol. Moving to the smaller cap would take XLM down to $0.08552696, which is 0.481x 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.
$0.08552696 per XLM. That is NEAR Protocol's current market capitalisation of $3B divided across the 35,134,151,599 XLM in circulation.
0.481x. Stellar trades at $0.1779 today and NEAR Protocol's market cap is $3B against Stellar's $6.25B.
No. It is one division: NEAR Protocol'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 $3B of market cap spread over more coins gives a lower price per coin. This uses the 35,134,151,599 XLM in circulation now.
