I would not be thinking that far for ethereum yet. I want to see ethereum 2.0 first and how the community will react to it.
competitors only in words. Ethereum has a very strong team and other projects (at the moment) can not bypass Ethereum in terms of marketing and development, as funding will not be enough.
Do not be so sure about that. Have you actually studied the other blockchains competing with eth? Or did you just look at their respective prices?
