Arithmetic on today's supply, not a forecast. It assumes nothing about whether Bitcoin Cash could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Bitcoin Cash has 20,041,297 BCH in circulation at $226.1000 each, which is $4.53B. Holding that supply still and putting Internet Computer's $1.5B in its place gives $74.9935 per BCH.
Bitcoin Cash is already worth more than Internet Computer. Moving to the smaller cap would take BCH down to $74.9935, which is 0.332x 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 BCH at that level, which is the part that actually decides a price.
$74.9935 per BCH. That is Internet Computer's current market capitalisation of $1.5B divided across the 20,041,297 BCH in circulation.
0.332x. Bitcoin Cash trades at $226.1000 today and Internet Computer's market cap is $1.5B against Bitcoin Cash's $4.53B.
No. It is one division: Internet Computer's market capitalisation spread over the supply of BCH that exists today. It assumes nothing about whether Bitcoin Cash 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 $1.5B of market cap spread over more coins gives a lower price per coin. This uses the 20,041,297 BCH in circulation now.
