I don't think so. Nothing is going to have any impact on ethereum price anymore. It is too big to oppose for new coins in market. Tezos might be bit older but its going to be new player anyways.. So 0 chance.
I believe the same thing. I don't understand why would any project for that matter will have a big impact positive or negative on a much older and already entrenched cryptocurrency like Ethereum. It is actually the other way around...Tezos can be affected by Ethereum or Bitcoin for that matter. Anyway, good luck to Tezos am hoping it can reach the potential that should have materialized a long time ago if not for the infighting that happened within the project. This was one of the ICOs which I invested on last year and which I have already forgotten to care.
