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 35,205,862,542 XLM in circulation at $0.1676 each, which is $5.9B. Holding that supply still and putting Zcash's $21.05B in its place gives $0.59793845 per XLM.
A 3.57x move is modest, and a coin this far down the table reaching the one above it is the ordinary shape of a cycle, not an outlier.
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.
$0.59793845 per XLM. That is Zcash's current market capitalisation of $21.05B divided across the 35,205,862,542 XLM in circulation.
3.57x. Stellar trades at $0.1676 today and Zcash's market cap is $21.05B against Stellar's $5.9B.
No. It is one division: Zcash'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 $21.05B of market cap spread over more coins gives a lower price per coin. This uses the 35,205,862,542 XLM in circulation now.
