Yes i agree with you i find the technology of ethereum better than that from bitcoin and i believe a lot of people already know that ethereum is the true rival of bitcoin as some people prefer ethereum over bitcoin.
Things are not so simple people apply this kind of thought as if changing currencies was as easy as changing your TV, bitcoin is better than the US dollar and yet the US dollar is still the number one currency so not everything is about which currency is the best, most of the time it is about the currency that is used by the most people.
