In 2021, also before then, you would hear it loud that Ethereum will beat Bitcoin one day, yes in their dreams. 
People who compare Ethereum with Bitcoin are ignorant. We cannot compare Ethereum with Bitcoin. Bitcoin is the best ever and will be in the future. Bitcoin's market cap is $1.90T while Ethereum's is $328B. From here we should understand that Ethereum has yet to break the all-time high value record, so why do we compare Ethereum with Bitcoin. Ethereum can be called the best among altcoins, Ethereum can be considered trusted and reliable among altcoins but should never be compared to Bitcoin.
