Cardano's Ada token was then made available for trading on the 1st October at Bittrex exchange." Looking at the Worldcoinindex chart, Cardano was at $0.03 on November 25, and was above $0.42 in the last 24 hours. Now at $0.3916 with a "market capitalization" of $12.18 billion (Worldcoinindex) or $10.01 billion (Coinmarketcap). Roughly equal with IOTA for the 6th highest 'value' coin, behind only Bitcoin, Ethereum, BitcoinCash, Ripple and Litecoin. Quite incredible since it appears the coin has been in existence for less than 3 months. .
