Arithmetic on today's supply, not a forecast. It assumes nothing about whether Bitway could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Bitway has 2,789,881,122 BTW in circulation at $0.5537 each, which is $1.54B. Holding that supply still and putting Zcash's $19.39B in its place gives $6.9489 per BTW.
Bitway would have to take on $17.84B of new money to get there. A 12.5x 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 BTW at that level, which is the part that actually decides a price.
$6.9489 per BTW. That is Zcash's current market capitalisation of $19.39B divided across the 2,789,881,122 BTW in circulation.
12.5x. Bitway trades at $0.5537 today and Zcash's market cap is $19.39B against Bitway's $1.54B.
No. It is one division: Zcash's market capitalisation spread over the supply of BTW that exists today. It assumes nothing about whether Bitway 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 $19.39B of market cap spread over more coins gives a lower price per coin. This uses the 2,789,881,122 BTW in circulation now.
