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?
You know one truth is, comparing two big projects or two outstanding projects is always tough, tough in the sense that both team knows what they want and are already working towards a long term goal.
Now coming to the discussion at hand, Ethereum is one coin that many coins are challenging often and on, and yet it keeps surprising them with its growth. To make is more explanatory, during the bull run Ethereum gas fee was nothing to write home about and many projects were migrating, one would have thought that would be the end, but look at the growth so far.
ADA on the other hand shows its team are always silently and diligently working hence the reason people are comparing the two coins.
But however, Ethereum have no competitor in my own opinion, because many projects are in one way or the other taking a leaf from it, which means it is the best, many projects are still launching on it, there are also many layer 2 tech; thus there will be no bigger market cap than that of Ethereum with the exemption of Bitcoin.
