The only alt coins I see as superior possibly are where the base idea for utility and efficiency on that blockchain could exceed Bitcoin maybe, all this talk of alt coins is like swear words to a large part of the forum who think only BTC can ultimately succeed as it is the most secure and so superior blockchain. However innovation is what Im looking for, I still think proof of stake could outperform for the common people where as the largest operators in crypto dont need this but I think it favors the smallest elements and so stays true to the original basis for BTC which it bits not billions
people aren't saying bitcoin is the only thing that
can succeed, they are saying that others aren't trying to succeed. instead when you look at altcoins you can clearly see that their goal is to get the biggest pump and dumps and make the most amount of money from it.
the reason why everyone hates ETH so much is because of its numerous issues. for starters it is centralized and mutable. two fundamental characteristics of a successful project simply doesn't exist in this altcoin. the only innovation that it had was the idea of smart contracts that are more advanced that what bitcoin (the currency) allows. but that idea was executed very poorly on a buggy platform. and that's just the tip of the iceberg.
as for PoS that you mentioned here, it is a very poor algorithm for a cryptocurrency. it has lots of attack vectors and adds certain weaknesses to a cryptocurrency that it automatically guarantees its lack of security.
