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 34,956,700,398 XLM in circulation at $0.1802 each, which is $6.3B. Holding that supply still and putting Rain's $11.19B in its place gives $0.32005565 per XLM.
The two are close in size, so the answer is a 1.78x move. Stellar and Rain are within a factor of two of each other by market capitalisation.
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.
$0.32005565 per XLM. That is Rain's current market capitalisation of $11.19B divided across the 34,956,700,398 XLM in circulation.
1.78x. Stellar trades at $0.1802 today and Rain's market cap is $11.19B against Stellar's $6.3B.
No. It is one division: Rain'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 $11.19B of market cap spread over more coins gives a lower price per coin. This uses the 34,956,700,398 XLM in circulation now.
