shitcoins like ethereum can't solve their own limited functionality and the backdoors they have let alone attempt at bigger more serious stuff that bitcoin is dealing with 
Ethereum is not a shit coin per say. Its more like Ethereum blockchain is the playground for shitcoins. That said, Ethereum is a very convenient utility coin that can host all kinds of coin projects. Can't blame Eth if the projects turn out it be shit in the end. Ethereum has served its purpose.
