You compare incomparable! Bitcoin and Ethereum are completely different assets. Bitcoin is the father of all cryptocurrencies and it leads them. Just look through the markets history! When BTC pumps, alts start their growth also. When BTC dumps, all alts also dump. These processes are permanent.
True, it is clear that the two will not be comparable in comparison, because the first to be born will still be the King of crypto coins, namely Bitcoin, and those born after that are Alternative tokens that often have an influence when Pump and Dump on Bitcoin.
Ethereum will not beat bitcoin, not now and in the future. As long as people still use bitcoin as their main investment, they will not choose ethereum to be their investment, but maybe they will ethereum to make money like bitcoin. We can not force people who say ethereum could beat bitcoin because maybe they will have their opinion that we do not know and they do not want to say to us. Bitcoin will be the best asset of 2021, and many people will save more bitcoin before the price jump higher.
