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 personally feel that Ethereum will soon cover bitcoins' craze in the market in the coming years as it has some great potential comparing to bitcoin. I agree with the fact that the bitcoin is the first cryptocurrency introduced in the crypto market with good security norms and features. But i still remember that Ethereum is the major blockchain payment gateway in managing the other cryptocurrency and it has good potential and long way to go. I agree that Ethereum still has to improve a lot in their blockchain and security features and once we see the improvement and growth we will definitely see Ethereum beating the bitcoin.
