Arithmetic on today's supply, not a forecast. It assumes nothing about whether Hedera could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Hedera has 43,711,736,138 HBAR in circulation at $0.0756 each, which is $3.3B. Holding that supply still and putting XRP's $85.54B in its place gives $1.9569 per HBAR.
Hedera would have to take on $82.23B of new money to get there. A 25.9x 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 HBAR at that level, which is the part that actually decides a price.
$1.9569 per HBAR. That is XRP's current market capitalisation of $85.54B divided across the 43,711,736,138 HBAR in circulation.
25.9x. Hedera trades at $0.0756 today and XRP's market cap is $85.54B against Hedera's $3.3B.
No. It is one division: XRP's market capitalisation spread over the supply of HBAR that exists today. It assumes nothing about whether Hedera 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 $85.54B of market cap spread over more coins gives a lower price per coin. This uses the 43,711,736,138 HBAR in circulation now.
