Arithmetic on today's supply, not a forecast. It assumes nothing about whether Uniswap could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Uniswap has 623,724,532 UNI in circulation at $6.3950 each, which is $3.99B. Holding that supply still and putting Hedera's $3.31B in its place gives $5.3137 per UNI.
Uniswap is already worth more than Hedera. Moving to the smaller cap would take UNI down to $5.3137, which is 0.831x 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 UNI at that level, which is the part that actually decides a price.
$5.3137 per UNI. That is Hedera's current market capitalisation of $3.31B divided across the 623,724,532 UNI in circulation.
0.831x. Uniswap trades at $6.3950 today and Hedera's market cap is $3.31B against Uniswap's $3.99B.
No. It is one division: Hedera's market capitalisation spread over the supply of UNI that exists today. It assumes nothing about whether Uniswap 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 $3.31B of market cap spread over more coins gives a lower price per coin. This uses the 623,724,532 UNI in circulation now.
