For me, I don't think that Ethereum can beat Bitcoin as the Number One in the crypto market, it's because Bitcoin is getting more and more bigger each day because there are more investors coming every time and Ethereum still has a lot to improve in their blockchain and their security features.
I believe ethereum can grow in the future, maybe even parallel with bitcoin. This is because the ethereum community gets bigger with the various projects that use it, so the more demand. However, to be parallel to bitcoin, ethereum takes a long time because bitcoin is also very strong.
