As the subject goes, can we expect the newly developed Altcoin that can go beyond Bitcoin?
Better in terms of what? If in terms of transaction speed, yes, and we already have faster altcoins. If in terms of fees, yes, and we already have altcoins offering much lower fees. If in terms of anonymity, yes, and we have much more private altcoins. So in terms of scalability, privacy, and other features we have much better altcoins. But the face of crypto is Bitcoin. Bitcoin is the god of crypto. Bitcoin is trusted, used, accepted, owned, coveted, etc more than all the altcoins combined.
What more can we ask for? This is ultimately complete and a strong currency for now, and even fiat cash couldn't overtake what legacy did bitcoin brought to us. Making bitcoin as God of crypto, can't be aligned to that but maybe I believed it was a father of crypto. If somebody can generate something that's more advantage beyond bitcoin's feature, I bet it's too difficult for him unless he is investing the entire saving he had and he should be one of the whales to establish an own cryptocurrency business.
Bitcoin is not ultimately complete as what you've said. It is not the strongest currency because it is in fact more used not as a currency but as an asset or a store of value. Bitcoin needs to develop further for it to become a strong currency. But fundamentally, Bitcoin is already great and we are going to become a better currency someday.
