Arithmetic on today's supply, not a forecast. It assumes nothing about whether Zcash could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Zcash has 16,991,492 ZEC in circulation at $1,238.60 each, which is $21.05B. Holding that supply still and putting Shiba Inu's $2.86B in its place gives $168.1168 per ZEC.
Zcash is already worth more than Shiba Inu. Moving to the smaller cap would take ZEC down to $168.1168, which is 0.136x 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 ZEC at that level, which is the part that actually decides a price.
$168.1168 per ZEC. That is Shiba Inu's current market capitalisation of $2.86B divided across the 16,991,492 ZEC in circulation.
0.136x. Zcash trades at $1,238.60 today and Shiba Inu's market cap is $2.86B against Zcash's $21.05B.
No. It is one division: Shiba Inu's market capitalisation spread over the supply of ZEC that exists today. It assumes nothing about whether Zcash 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 $2.86B of market cap spread over more coins gives a lower price per coin. This uses the 16,991,492 ZEC in circulation now.
