Ethereum have conquered this year it had its peak last year and so with bitcoin but the problem is bitcoin returned to its almost original value while eth has maintained its value.
I believe that each of these projects has its pros and cons. On the ERC-20 platform, almost all new projects come out, but Bitcoin has a more developed infrastructure, many ordinary people do not know that apart from bitcoin, there are other crypto-currencies. In the future, I personally would have given preference to ETH!
