At the time of writing, the token traded at $6.23, which translates to a market capitalisation of $5.63 billion. This market capitalisation is just about enough for Dot to displace the Link token from its current position.
Coinmarketcap officially ranks the token at number 2172. The market capitalisation of a token or coin is determined by multiplying the price of a token with the circulating supply. Information on the Coinmarketcap website suggests "the organisation has not sufficiently verified the circulating supply and resulting market cap yet."
