The community named it to be a much better version of ETH.
ADA is slowly building its momentum to be the best digital cash available summing up the scalability, high security, low transaction fees, interoperability and especially considering the backlash of ETH with current gas fees.
Also the creator strongly believes that cryptocurrency absolutely have to communicate one with another and most likely this will happen in the next 3-5 years and there are rumors of Cardano/Litecoin connection bridge.
Can we see a market cap bigger than Ehereums? At the actual price rates this means it should be around $12 per ADA.
Will it happen?
For now, the bigger market cap is Cardano (ADA), BNB is already below it, although in general, this BNB is very popular compared to Cardano (ADA), maybe in the future Cardano (ADA) will also step over ETH Rank two, this is difficult but Cardano's market cap is good.
