Arithmetic on today's supply, not a forecast. It assumes nothing about whether Polkadot could attract that much money.
A coin's market capitalisation is its price multiplied by the number of coins in circulation. Polkadot has 1,692,279,772 DOT in circulation at $1.0120 each, which is $1.71B. Holding that supply still and putting Gram (prev. Toncoin)'s $3.81B in its place gives $2.2515 per DOT.
A 2.22x move is modest, and a coin this far down the table reaching the one above it is the ordinary shape of a cycle, not an outlier.
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 DOT at that level, which is the part that actually decides a price.
$2.2515 per DOT. That is Gram (prev. Toncoin)'s current market capitalisation of $3.81B divided across the 1,692,279,772 DOT in circulation.
2.22x. Polkadot trades at $1.0120 today and Gram (prev. Toncoin)'s market cap is $3.81B against Polkadot's $1.71B.
No. It is one division: Gram (prev. Toncoin)'s market capitalisation spread over the supply of DOT that exists today. It assumes nothing about whether Polkadot 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 $3.81B of market cap spread over more coins gives a lower price per coin. This uses the 1,692,279,772 DOT in circulation now.
