Arithmetic on today's supply, not a forecast. It assumes nothing about whether Aster could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Aster has 2,697,539,091 ASTER in circulation at $0.694 each, which is $1.87B. Holding that supply still and putting Zcash's $19.26B in its place gives $7.1400 per ASTER.
Aster would have to take on $17.39B of new money to get there. A 10.3x move is large: it happens, and it usually needs the whole market to grow instead of one coin to take share from another.
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 ASTER at that level, which is the part that actually decides a price.
$7.1400 per ASTER. That is Zcash's current market capitalisation of $19.26B divided across the 2,697,539,091 ASTER in circulation.
10.3x. Aster trades at $0.694 today and Zcash's market cap is $19.26B against Aster's $1.87B.
No. It is one division: Zcash's market capitalisation spread over the supply of ASTER that exists today. It assumes nothing about whether Aster 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 $19.26B of market cap spread over more coins gives a lower price per coin. This uses the 2,697,539,091 ASTER in circulation now.
