Popular Crypto exchange Binance has recently launched a ‘Bluebird Index’, a cryptocurrency index that tracks the performance of its own native token, $BNB, Dogecoin ($DOGE), and a little-known cryptocurrency called Mask Network ($MASK). This index is calculated using a formula incorporating the “weighted averages of the constituent tokens’ real-time prices on the Binance Spot market.” Following this launch, several users claim Binance is hinting at the coins that will be a part of a future Twitter integration into Web3.
